[Jens]

Hallo,

ich habe damit begonnen Literatur über die Trilobiten von Marokko rauszusuchen. Hauptsource ist die tolle Arbeit von Jell & Adrian 2002, die alle verfügbaren Trilobitengattungen aufgelistet haben. Daraus habe ich die Gattungen ermittelt, die erstmals aus Marokko beschrieben wurden. Das sind bis 2002 immerhin 53 Gattungen. Allerdings umfaßt die Literaturliste bisher fast nur die Arbeiten in denen neue Gattungen aufgestellt wurden. Andere vielleicht wichtige Arbeiten, in denen neue Arten beschrieben wurden, aber keine Gattungen fallen so erstmal durch Suchraster. Es gibt viel viel mehr Trilos in Marokko, aber Koneprusia, Ceratarges und co. wurden halt zu erst in Europa gefunden und beschrieben.
Ich denke aber, daß die Literatur den Einstieg in die marokkanische Trilobitentaxonomie ermöglichen sollte.

Grüsse,
Jens

Dank eines Feedbacks von Mirco Alberti wissen wir uebrigens nun, dass die gefaleschten marokkanischen Homalonotiden zur Gattung Scabrella gehoeren und nicht Burmeisterella, wie anfaenglich ohne naeheres Insiderwissen vermutet.

Infos zu Scabrella findet man unter (oder wird man finden):

Thankz to Mirco:

Müller, P. (im Druck): im 3. Eifel-Trilobiten Band (Martin Basse) wird er die verschiedenen Homalonoten des rheinischen Devons beschreiben.

Ws. in 2005 wird auch noch eine weitere Arbeit von Peter Müller erscheinen, die sich speziell mit der Gattung Scabrella (sowohl der rheinischen, der iberischen, als auch der marokkanischen Arten) befassen wird. Peter hat dazu etliche private und wissenschaftliche Sammlungen durchforstet, sowie selbst in Marokko gesammelt und dabei etliches Material zusammengetragen um eine möglichst umfassende Beschreibung der Gattung liefern zu können.

Gruesse,

Abstract
Middle Ordovician formations of the Anti-Atlas ranges of southern Morocco provided a diverse record of trilobites, molluscs, echinoderms, brachiopods, graptolites and micro- and ichnofossils from about 180 fossil localities. These were mainly found during the national geological mapping to the 1:200.000 scale, and most of them remained unreferenced until now. The lithostratigraphic position of all fossil localities is briefly studied showing, in some cases, noteworthy discrepances with previous works. Besides this stratigraphical reappraisal, a review of the fossil record for each formation and locality is done, together with a taxonomical update. From a chronostratigraphical point of view, the whole sucession constituted by the Tachilla Formation and First Bani Group formations are here referred to the Mediterranean regional scale. The Oretanian-Dobrotivian and Dobrotivian-Berounian boundaries are located respectively in the Bou-Zeroual Formation and at the top of the Izegguirene Formation. The transition between the lower and upper Oretanian is provisionally established in the upper third of the Tachilla Formation, and those between the lower and upper Dobrotivian at the base or in the lower part of the Ouine-Inirne Formation. A general correlation with the global standard and British regional scales is also suggested for the Middle Ordovician of the Moroccan Anti-Atlas. The basal limit of the Upper Ordovician series probably lies within the lower part of the Izegguirene Formation. Paleobiogeographical data confirm the interest of this area as an important diversification center for many Mediterranean faunas that underwent remarkable dispersal in northern Gondwanan shelves.

Abstract
The faunal analysis of the Upper Fezouata Shales Formation (Arenig, central Anti-Atlas, Morocco) shows five distinct associations, one of graptolites and four of trilobites, and an environment is proposed for each one. The results obtained from the sedimentary facies confirm this interpretation and allow the environment of the trilobite biofacies and transport phenomena on a storm-dominated marine platform to be defined.

ABSTRACT: Similarities in biotic successions support a unified, composite chronostratigraphy for the Lower-Middle Cambrian of the Iberian and Moroccan margins of West Gondwana. The Cordubian Series (emended from an Iberian stage-level unit) comprises the sub-trilobitic Lower Cambrian of West Gondwana. This series represents ca. half of the Cambrian (ca. 25 m.y.), has a base defined at the lowest occurrence of diagnostic Cambrian ichnogenera in central Spain, and is comparable to the Placentian Series of Avalon. The overlying trilobite-bearing Lower Cambrian (ca. 9 m.y. duration), or Atlasian Series (new), of West Gondwana consists of two stages originally defined in highly fossiliferous (trilobites and archaeocyaths) Moroccan sections where they have great potential for precise U-Pb geochronology. The penultimate Lower Cambrian stage, the Issendalenian, with the near-joint lowest occurrence of trilobites and archaeocyaths, is approximately comparable with the sparsely fossiliferous, Iberian "Ovetian Stage" (designation abandoned). The "Ovetian" as currently revised is invalid because it is an objective homonym of Sdzuy’s original "Ovetian." The "Ovetian" is not a practically applicable unit as its basal stratotype horizon lacks any identified fossils, and its trilobites are so rare that it cannot serve as a standard for interregional correlation. By contrast, the Banian Stage as defined in Morocco is suitable as the terminal Lower Cambrian stage of West Gondwana. It is based on very fossiliferous successions that allow recognition of three successive trilobite zones and is similar in concept to the Iberian "Marianian Stage" (designation abandoned). The "Marianian" lacks a designated lower boundary stratotype locality, lacks a biostratigraphically defined base at a stratotype, and is so sparsely fossiliferous that no biostratigraphic zonation exists. Long-term problems involving regional definition of the West Gondwanan Lower–Middle Cambrian boundary are resolved. The lowest occurrence of paradoxidid trilobites, the classic index for the base of the Middle Cambrian, is diachronous in West Gondwana and other regions, with the group showing a delayed appearance in Iberia, Sweden, and Bohemia, by comparison with Morocco. Taxonomic revision of Iberian trilobites and new documentation of their ranges in Morocco show that the Iberian terminal "Lower Cambrian" "Bilbilian Stage" (designation abandoned) correlates with the Moroccan upper Banian and lower and middle "Tissafinian" Stages and with the Siberian upper Toyonian (traditionally assigned to the Lower Cambrian in Siberia) and lower Amgan (assigned to the Middle Cambrian in Siberia) Stages. The "Bilbilian" thus includes Middle Cambrian strata in a traditional international concept. Faunas from the base of the Iberian "lowest" Middle Cambrian "Leonian Stage" (designation abandoned) correlate largely into the second trilobite zone of the "Tissafinian" and are now understood to appear above an intra-Middle Cambrian faunal break. This faunal break is still poorly understood and may be an artifact of collection failure immediately above the sparsely fossiliferous, problematical "Valdemiedes event" interval. The base of this "Middle Cambrian", now termed Celtiberian Series (new designation), in West Gondwana is best defined by the base of the lower Middle Cambrian Agdzian Stage (new designation). The Agdzian includes the "Tissafinian" and overlying lower "Toushamian Stage" (designations abandoned) of Morocco, and has its top defined by the base of the middle Middle Cambrian Caesaraugustian Stage, as defined in Spain at the lowest occurrence of Badulesia tenera. The Languedocian, originally defined at the lowest occurrence of Solenopleuropsis (Manublesia) thorali in the southern Montagne Noire of France comprises the third, and terminal stage of the Celtiberian Series. We suggest that the designations "Lower Cambrian" and "Middle Cambrian" be regarded as descriptive and non-chronostratigraphic terms in discussions of the Cambrian. New taxa or taxonomic combinations include Myopsolenites altus (Linán & Gozalo, 1986), M. boutiouiti sp. nov., M. kielciensis (Bednarczyk, 1970), and Hamatolenus (Hamatolenus) vincenti sp. nov.

Im Yahoo-Forum wurde (durch jhcook) vor geraumer Zeit eine Seite verlinkt, auf der Trilobiten aus der älteren Literatur über Marokko vorgestellt werden.

Der Link für das Gattungsverzeichnis ist folgender:

http://www.paleontolyon.org/trilo01/recherches_autres.php?autres=genre

Schwerpunkt liegt auf kambrischen Trilos, aber es sind auch ordovizische und devonische mit dabei.

Es ist auch eine gute Idee sich die Arten nach Autoren geordnet anzusehen. Da nicht alles in der Kurzfassung enthalten ist. So sind aus einer Arbeit 88 Exemplare (Typusmaterial, Syn- und Holotypen) von Thoral, 1946 mit abgebildet. Hierbei handelt es sich aber um französisches Material.

ABSTRACT

A review of all known species of the scutelluine trilobite Paralejurus corroborates its distinction from contemporaneous representatives of the subfamily. The overall morphology together with observed habitat conditions favor the view of its having had a semiendobenthic life habit analogous to that of many earlier illaenids. Particular features that are shared with the Silurian Rhaxeros, such as the pronounced convexity of the exoskeleton and the wide axis, are considered as homeomorphies related to a burrowing lifestyle rather than the expression of phyletic relationships. The data set based on conodont biostratigraphy reveals earliest occurrences of Paralejurus in the Pragian and the disappearance of last representatives at the base of the Middle Devonian. In the lower Early Devonian Paralejurus was restricted to the North Gondwana margin and related microplates. Later and in consequence of geodynamic plate movements that led to the reduction of oceanic barriers, the Paralejurus dormitzeri group succeeded in spreading to the epicontinental margin of Laurussia in Late Emsian times. New material from Southern Morocco, including Paralejurus spatuliformis n. sp. and Paralejurus tenuistriatus n. sp., and the first representative of the genus from Spain, Paralejurus carlsi n. sp., are described. Paralejurus dormitzeri rehamnanus Alberti, 1970 is considered an independent species emphasized by the discovery of complete exoskeletons.

Abstract:
Fossiliferous Tremadocian (lowermost Ordovician) schists with interbedded pyroclastics have been discovered in the central Bani and Taouz (Tafilelt) regions, Morocco, separated by a distance of some 150 kilometers in the central Anti-Atlas range. Seven fossil zones (graptolites and trilobites) are distinguished in the central Bani region, where the Tremadocian is over 300 meters thick.

Abstract:
New stratigraphic subdivisions in the Ordovician series are based mainly on tectonic (epirogenic movement) and paleontological criteria, thanks to the discovery of graptolites and trilobites. Several sedimentation basins have been brought to light, related to epirogenic movements of a notably positive nature which have affected both branches of the Anti-Atlas. The broad lines of geological and tectonic history have been sketched and rough comparisons have been made with neighbouring regions (Sahara, Mediterranean basin and Normandy).

Abstract:
The faunal analysis of the Upper Fezouata Shales Formation (Arenig, central Anti-Atlas, Morocco) shows five distinct associations, one of graptolites and four of trilobites, and an environment is proposed for each one. The results obtained from the sedimentary facies confirm this interpretation and allow the environment of the trilobite biofacies and transport phenomena on a storm-dominated marine platform to be defined.

Abstract:
From consideration of earliest Olenellina and Redlichiina versus later members of those groups it is argued from ontogenetic, outgroup and stratigraphic data that the detached (natant) hypostomal condition is primitive and the attached (conterminent) condition derived. Several early redlichioid genera are demonstrated to resemble earlier olenelloid genera more closely than they do other redlichioids, begging the question "did facial sutures evolve more than once among trilobites?" At least five separate lineages, from different very early Olenellina (Fallotaspidoidea), are identified, in each of which dorsal facial sutures appeared independently. These involve transition between the following pairs of genera or very closely related forms: Profallotaspis and Bigotina in Siberia; Archaeaspis and Uktaspis in Siberia; Eofallotaspis and Lemdadella in Morocco; Repinaella and Elganellus in Siberia; Choubertella and Yunnanocephalus in Morocco and China. Thus the Redlichiina, as constituted in the 1997 Treatise, is considered polyphyletic. Some preliminary speculations on evolutionary pathways between major groups in the Early Cambrian are outlined.

Abstract:
Although known for more than a century, the Early Cambrian trilobite faunas of the Brigus Formation of the Avalon Terrane, Newfoundland, remain poorly documented. The formation comprises two depositional sequences that correspond to the St. Mary's and overlying Jigging Cove Members. The base of the St. Mary's Member is a diachronous unconformity with the sub-trilobitic Lower Cambrian and older rocks as low as those of the upper Precambrian Avalonian orogen. All previously described trilobites occur in the St. Mary's Member, which is composed of dominantly red and purple siliciclastic mudstones and minor nodular to bedded carbonates that were deposited from near storm-wave base to peritidal settings. Trilobites are the dominant faunal elements of subtidal carbonates, with minor small shelly fossils and a near-absence of mollusks. The ellipsocephaloid Strenuella occurs in almost all collections, as does the eodiscoid Hebediscus. Other common components of the St. Mary's fauna include Callavia, Acanthomicmacca and Serrodiscus. Onlap of the St. Mary's Member and the appearance of its eodiscoids is roughly correlated with eustatic rise recorded on other continents (e.g., Sinsk event in Siberia, upper Issafen Formation in Morocco). The trilobite assemblage of the St. Mary's Member, generally assigned to the Callavia broeggeri Zone, is largely replaced at the sequence boundary with the terminal Lower Cambrian Jigging Cove Member (lower dysaerobic green and higher, oxygenated purple and red siliciclastic mudstones with nodular carbonates. The Jigging Cove has a sparse fauna of undescribed ellipsocephaloids. Although the St Mary's Member records shallow subtidal conditions over most of southeast Newfoundland, peritidal carbonates occur in it near the southern tip of the Burin Peninsula. Here, assemblages are dominated by condensed hyolith and small shelly fossil packstones, but trilobites are very rare. This suggests that the initial Cambrian diversification of trilobites in Avalonia was concentrated in offshore, rather than nearshore environments.

Abstract:
Eodiscoid trilobites are important for correlations of upper lower Cambrian and lower middle Cambrian strata. Five species of eodiscoids are known from the middle Cambrian of Scandinavia: Eodiscus scanicus (Linnarsson, 1883), E. borealis Westergard, 1946, E. punctatus (Salter, 1864), Dawsonia oelandica (Westergard, 1936), and Opsidiscus bilobatus (Westergard, 1946). Dawsonia oelandica is redescribed and reconstructions of the dorsal surface are presented. The study is based on specimens collected by Anton H. Westergard from two localities on the island of Oland, supplemented with new material from Jamtland, central Sweden. The Oland specimens (four cephala and one pygidium) are preserved in a greenish grey, arenaceous shale, and were collected from the Mossberga drill core and a locality near Morbylanga. The Jamtland material is from a single block of a dark grey limestone collected by Tomas Weidner at Mon, south of Ostersund. The Jamtland material includes five well preserved cephala and two nearly complete pygidia, providing additional information on the species. All the available material is from the Ptychagnostus praecurrens Zone (formerly the Eccaparadoxides pinus Zone) of the lower middle Cambrian, which approximately correlates with the Eccaparadoxides benetti Zone of western Avalonia, the "Paradoxides" harknessi Zone of eastern Avalonia, and the Kymataspis arenosa Zone of Morocco. The external exoskeletal surface of D. oelandica is distinctly granulose, particularly on the cheeks, the anterior border, the posterior part of the occipital spine, and on the pleural fields of the pygidium. The stoutly-based occipital spine is about as long as the cephalon, and rises at approximately 45 degrees from the horizontal. The third and fourth pygidial axial rings probably had prominent, vertically directed spines. The material also shows the presence of a spine on the posterior thoracic axial ring. The intraspecific variability, the ontogeny, and the possession of probable sensory organs are discussed.

Special Papers in Palaeontology (October 2003), 70 73-102


Abstract:
Correlation of continental Cambrian sequences is accomplished by the recognition of cosmopolitan oceanic agnostid, eodiscid and oryctocephalid taxa on their shelf edges. In this account, species of Peronopsis, Condylopyge, Acidiscus, Bathydiscus, Cephalopyge, Kiskinella and Ovatoryctocara are highlighted amongst these taxa, of which O. granulata Tchernysheva, 1962, occurring in Siberia and south-eastern Newfoundland (within paradoxidid sequences) and with Arthricocephalus chauveaui Bergeron, 1899 in Greenland (below the extinction of Olenellus) and South China (below Bathynotus and the extinction of Redlichia), affords a correlation to indicate a temporal overlapping of the ranges of Olenellus, Redlichia, and early paradoxidid species of Acadoparadoxides and Eccaparadoxides. Such a correlation indicates different bases of the "Middle Cambrian" in the various faunal realms and that the base of O. granulata sequences may be considered a suitable marker level as a global stage boundary. In support of the correlation, new details of the south-eastern Newfoundland sequence and its trilobites are given, together with the descriptions of the new taxa, Bathydiscus taconicus and Protolenus (Hupeolenus) mckillopi, in addition to Newfoundland specimens of O. granulata. The occurrence of Oryctocephalus indicus (Reed, 1910) [= reticulatus Lermontova, 1940] in the Siberian Kounamkites Zone further supports the correlations in Table 1.

Non-traditional concepts (such as carbon isotope signatures), microplankton (such as acritarchs), and most invertebrate fossils (e.g., brachiopods) may act as auxiliary tools for intercontinental correlation of regional calibration but are unable to provide the base for fine-scaled global correlation at present. As a result, the selection of a Global Stratigraphic Section and Point will have to root on trilobites which appear to be the only reliable index fossils to define such a GSSP. Five possible levels of correlation within the traditional Lower-Middle Cambrian boundary interval have been discussed: (1) the FAD of Oryctocephalus indicus; (2) the FAD of Ovatorydocara granulata and/or Kiskinella cristata; (3) the FAD of Arthricocephalus chauveaui; (4) the base of the Acidiscus-Cephalopyge assemblage "zone"; and (5) the base of the STH "band". The potentials of these levels are analyzed in this study. All of them suffer from certain deficiencies such as limited insight into the stratigraphic ranges of key species; problems of confident identification of the index species; or absence of key faunal elements on certain Cambrian continents; that make them invalid for high-precision correlation on a global scale. However, the combination of (1) through (4) promises an intercontinental correlation that can be used as a global framework, which will be sufficiently accurate to serve normal correlation purposes.

Hat zwar nur um die Ecke was mit Marokko zu tun, klingt aber interessant. Ich wußte gar nicht, daß in Massachusetts auch Paradoxiden und Proteleniden vorkommen. Von Neufundland kennt man ja die tollen Funde (s. Levi-Setti). Der an Laurentia angedockte Avalonia-Krustensplitter ist wohl doch größer (als ich in Erinnerung hatte).
Spannend sind die engen Beziehen zu Gondwana (Marokko und Spanien) bei den Ellipsocephaloidea , zB. der Hamatolenus (möglicherweise sogar auf Artniveau).

Abstract:
The Cambrian fauna of Massachusetts, characterized by Paradoxides (Hydrocephalus) harlani, is poorly preserved. Better-preserved specimens, occurring within the stratigraphic range of this trilobite in southeastern Newfoundland and Morocco, provide a better understanding of such taxa to widen the scope of correlation. The paradoxidid-bearing Braintree Formation has revealed three trilobite species to add to those recently recorded. They represent Ellipsocephaloidea not previously recognized in this Massachusetts sequence, namely Protoleninae by Hamatolenus (H.) aff. H. (H.) marocanus and H. (Myopsolenus) aff. H. (M.) magnus and Ellipsocephalidae by Holocephalina aff. H. levis, thus strengthening faunal relationships with midshelf Cambrian sequences in Morocco and Spain. Reinterpretations of Agnostida, based on Newfoundland material associated with P. (Hydrocephalus) harlani, indicate that Condylopyge eli and Kiskinella cf. K. cristata signify a stratigraphic position for part of the Massachusetts sequence a little above the first appearance of Ovatoryctocara granulata. Appearance of this latter species is under review as the basal boundary of a global Cambrian stage, and is below the sequence break within the Chamberlain's Brook Formation in Newfoundland marked by the Easter Cove Blister Bed. The problem of differentiating species with numerous variable growth stages is highlighted in the ontogenies and stratigraphic ranges of P. (H.) harlani and P. (Plutonides) haywardi and emphasizes the importance of cephalic morphology in paradoxidid classification. Details of the holotypes of Agraulos quadrangularis and Braintreella rogersi and Czech topotypes of Agraulos ceticephalus supplement generic and specific characters poorly understood, especially those involving proportional differences between tectonically/taphonomically flattened examples and undistorted high-relief specimens.

Although Middle Cambrian trilobites of the Braintree Member in eastern Massachusetts were among the first published on in North America, re-examination of this fauna has led to wholesale taxonomic and biostratigraphic re-evaluation. This low diversity fauna now includes at least seven species, with the first report of agnostoids (three poorly preserved taxa) and the ellipsocephalid Kingaspis avalonensis new species. Paradoxides (Acadoparadoxides) harlani Green emend., a senior synonym of P. (A.) haywardi Raymond, allows correlation into the lowest Middle Cambrian elsewhere in Avalon. However, all the polymeroid species are endemic, and this precludes a highly resolved correlation into other Cambrian paleocontinents. A breakdown of provincial barriers in the late Early Cambrian as western Gondwana passed from equatorial to the higher south latitudes of Avalon led to faunal exchanges between these continents. Paradoxides (Acadoparadoxides) and Kingaspis of the Braintree fauna are shared with western Gondwana, while Braintreella and "Agraulos" quadrangularis are closest to genera known from the Spanish, Moroccan, and Perunican (Bohemian) margins of Gondwana.
