  • Sequence of Post-Moult Exoskeleton Hardening Preserved in a Trilobite Mass Moult Assemblage from the Lower Ordovician Fezouata Konservat-Lagerstätte, Morocco
    Editors' choice Sequence of post-moult exoskeleton hardening preserved in a trilobite mass moult assemblage from the Lower Ordovician Fezouata Konservat-Lagerstätte, Morocco HARRIET B. DRAGE, THIJS R.A. VANDENBROUCKE, PETER VAN ROY, and ALLISON C. DALEY Drage, H.B., Vandenbroucke, T.R.A., Van Roy, P., and Daley, A.C. 2019. Sequence of post-moult exoskeleton hardening preserved in a trilobite mass moult assemblage from the Lower Ordovician Fezouata Konservat-Lagerstätte, Morocco. Acta Palaeontologica Polonica 64 (2): 261–273. Euarthropods have a tough exoskeleton that provides crucial protection from predation and parasitism. However, this is restrictive to growth and must be periodically moulted. The moulting sequence is well-known from extant arthropods, consisting of: (i) the long inter-moult stage, in which no changes occur to the hardened exoskeleton; (ii) the pre-moult stage where the old exoskeleton is detached and the new one secreted; (iii) exuviation, when the old exoskeleton is moulted; and (iv) the post-moult stage during which the new exoskeleton starts as soft, thin, and partially compressed and gradually hardens to the robust exoskeleton of the inter-moult stage. Trilobite fossils typically consist of inter-moult carcasses or moulted exuviae, but specimens preserving the post-moult stage are rare. Here we describe nine specimens assigned to Symphysurus ebbestadi representing the first group of contemporaneous fossils collected that preserve all key stages of the moulting process in one taxon, including the post-moult stage. They were collected from a single lens in the Tremadocian part of the Fezouata Shale Formation, Morocco. Based on cephalic displacement and comparison to other trilobite moults, one specimen appears to represent a moulted exoskeleton.

    Trilobites of the Hagastrand Member (Tøyen Formation, lowermost Arenig) from the Oslo Region, Norway. Part Il: Remaining non-asaphid groups OLE A. HOEL Hoel, O. A.: Trilobites of the Hagastrand Member (Tøyen Formation, lowermost Arenig) from the Oslo Region, Norway. Part Il: remaining non-asaphid groups. Norsk Geologisk Tidsskrift, Vol. 79, pp. 259-280. Oslo 1999. ISSN 0029-196X. This is Part Il of a two-part description of the trilobite fauna of the Hagastrand Member (Tøyen Formation) in the Oslo, Eiker­ Sandsvær, Modum and Mjøsa areas. In this part, the non-asaphid trilobites are described, while the asaphid species have been described previously. The history and status of the Tremadoc-Arenig Boundary problem is also reviewed, and I have found no reason to insert a Hunnebergian Series between the Tremadoc and the Arenig series, as has been suggested by some workers. Descriptions of the localities yielding this special trilobite fauna are provided. Most of the 22 trilobite species found in the Hagastrand Member also occur in Sweden. The 12 non-asaphid trilobites described herein belong to the families Metagnostidae, Shumardiidae, Remopleurididae, Nileidae, Cyclopygidae, Raphiophoridae, Alsataspididae and Pliomeridae. One new species is described; Robergiella tjemviki n. sp. Ole A. Hoel, Paleontologisk Museum, Sars gate l, N-0562 Oslo, Norway. Introduction contemporaneous platform deposits in Sweden are domi­ nated by a condensed limestone succession. In Norway, the The Tremadoc-Arenig Boundary interval is a crucial point Tøyen Formation is divided into two members: the lower in the evolution of several invertebrate groups, especially among the graptolites and the trilobites. In the graptolites, this change consisted most significantly in the loss of bithekae and a strong increase in diversity.

Why did the UV-A-induced photoluminescent blue–green glow in trilobite eyes and exoskeletons not cause problems for trilobites? PeerJ 3:e1492 https://doi.org/10.7717/peerj.1492 Why the UV-A-induced photoluminescent blue-green glow in trilobite eyes and exoskeletons did not cause problems for trilobites? Brigitte Schoenemann, Euan N.K. Clarkson, Gábor Hórváth The calcitic lenses in the eyes of Palaeozoic trilobites are unique in the animal kingdom, although the use of calcite would have conveyed great advantages for vision in aquatic systems. Calcite lenses are transparent, and due to their high refractive index they would facilitate the focusing of light. In some respects, however, calcite lenses bear evident disadvantages. Birefringence would cause double images at different depths, but this is not a problem for trilobites since the difference in the paths of the ordinary and extraordinary rays is less than the diameter of the receptor cells. Another point, not discussed hitherto, is that calcite fluoresces when illuminated with UV-A. Here we show experimentally that calcite lenses fluoresce, and we discuss why fluorescence does not diminish the optical quality of these lenses and the image formed by them. In the environments in which the trilobites lived, UV-A would not have been a relevant factor, and thus fluorescence would not have disturbed or confused their visual system.

  • Enrollment and Coaptations in Some Species of the Ordovician Trilobite Genus Placoparia
    Enrollment and coaptations in some sp eeies of the Ordovician trilobite genus Placoparia JEAN-LOUIS HENRY AND EUAN N.K. CLARKSON Henry, J.-L. & Clarkson, E.N.K. 1974 12 15: Enrollment and coaptations in some species of the Ordovician trilobite genus Placoparia. Fossils and Strata, No. 4, pp. 87-95. PIs. 1-3. Oslo ISSN 0300-949l. ISBN 82-00-04963-9. The species Pl. (Placoparia) cambriensis, Pl. (Coplacoparia ) tournemini and Pl. (Coplacoparia ) borni, described by Hammann (1971) from the Spanish Ordovician, are found in Brittany in formations attributed to the Llanvirn and the LIandeilo. The lateral borders of the librigenae of Pl. (Coplacoparia) tournemini and Pl. (Coplacoparia ) borni bear depressions into which the distal ends of the thoracic pleurae and the tips of the first pair of pygidial ribs come and fit during enrollment. These depressions, or coaptative structures sensu Cuenot (1919), are also to be observed in Pl. (Placoparia) zippei and Pl. (Hawleia) grandis, from the Ordovician of Bohemia. However, in the species tournemini and borni, additional depressions appear on the anterior cephalic border, and the coaptations evolve towards an increasing complexity. From Pl. (Placoparia) cambriensis, an ancestrai form with a wide geographic distribution, two distinct populations se em to have individu· alised by a process of allopatric speciation; one of these, probably neotenous, is represented by Pl. (Coplacoparia ) tournemini (Massif Armoricain and Iberian Peninsula), the other by Pl. (Placoparia ) zippei (Bohemia). Geo­ graphic isolation may be indirectly responsible for the appearance of new coaptative devices. jean-Louis Henry, Laboratoire de Paleontologie et de Stratigraphie, Institut de Geologie de l'Universite, B.P.

  • A Probable Case of Heterochrony in the Solutan
    A probable case of heterochrony in the solutan Dendrocystites Barrande, 1887 (Echinodermata: Blastozoa) from the Upper Ordovician of the Prague Basin (Czech Republic) and a revision of the family Dendrocystitidae Bassler, 1938 FLEUR NOAILLES, BERTRAND LEFEBVRE & LIBOR KAIÈKA The morphology of the Late Ordovician solutan Dendrocystites is reevaluated based on more than 300 specimens from the Letná and Zahořany formations (Prague Basin, Czech Republic). This genus is reported for the first time from the Bohdalec Formation, and its presence is confirmed in the Vinice Formation. The morphology of all specimens of the stratigraphically older species D. barrandei (Sandbian) is identical to that of small to medium-size individuals of D. sedgwicki (Katian). Distinctive characters of D. sedgwicki occur only in the largest specimens, and are all size-related (more asymmetrical thecal outlines, stronger ornamentation, rosetting pattern of thecal plates, proliferation of platelets in the proxistele). Consequently, the transition from D. barrandei to D. sedgwicki is interpreted as the result of heterochronic processes, with the largest individuals of D. sedgwicki displaying hyperadult morphologies (hyper- morphosis). Dendrocystites is locally abundant in both the Letná and Zahořany formations, but extremely rare in the deeper deposits of the Vinice and Bohdalec formations. This pattern coincides closely with first order fluctuations of the sea-level in the Prague Basin. The life orientation and implied feeding strategy of Dendrocystites and other solutans are both critically discussed. Several independent lines of evidence suggest that solutans were more likely detritus-feeders. Finally, it is proposed that two morphologically distinct patterns of dististele organization were elaborated independently from the polyplated, undifferentiated stalk-like appendage of Coleicarpus (plesiomorphic condition).

    2nd International Trilobite Conference (Brock University, St. Catharines, Ontario, August 22-24, 1997) ABSTRACTS. Characters and Parsimony. Jonathan M. Adrain, Department of Palaeontology, The Natural History Museum, London SW7 5BD, United King- dom; Gregory D. Edgecombe, Centre for Evolutionary Research, Australian Museum, 6 College Street, Sydney South, New South Wales 2000, Australia Character analysis is the single most important element of any phylogenetic study. Characters are simply criteria for comparing homologous organismic parts between taxa. Homology of organismic parts in any phylogenetic study is an a priori assumption, founded upon topological similarity through some or all stages of ontogeny. Once homolo- gies have been suggested, characters are invented by specifying bases of comparison of organismic parts from taxon to taxon within the study group. Ideally, all variation in a single homology occurring within the study group should be accounted for. Comparisons are between attributes of homologous parts, (e.g., simple presence, size of some- thing, number of something), and these attributes are referred to as character states. Study taxa are assigned member- ship in one (or more, in the case of polymorphisms) character-state for each character in the analysis. A single char- acter now implies discrete groupings of taxa, but this in itself does not constitute a phylogeny. In order to suggest or convey phylogenetic information, the historical status of each character-state, and of the the group of taxa it sug- gests, must be evaluated. That is, in the case of any two states belonging to the same character, we need to discover whether one state is primitive (broadly speaking, ancestral) or derived (representative of an evolutionary innovation) relative to the other.

  • The Middle Ordovician of the Oslo Region, Norway, 31. the Upper Caradoc Trilobites and Brachiopods from Vestbråten, Ringerike
    The Middle Ordovician of the Oslo Region, Norway, 31. The upper Caradoc trilobites and brachiopods from Vestbråten, Ringerike ALAN W. OWEN & DAVID A. T. HARPER Owen, A· W. & Harper, D.A. T.: The Middle Ordovician of the Oslo Region, Norway, 31. The upper Caradoc trilobites and brachiopods from Vestbråten, Ringerike. Norsk Geologisk Tidsskrift, Vol. 62, pp. 95-120, Oslo 1982. ISSN 0029-196X. The Norderhov Formation (new term) at Vestbråten, Ringerike, contains a diverse shelly fauna including 11 species of trilobites and 14 of brachiopods. These are described and indicate an approximate age of Woolstonian to early Actonian for the strata here. A. W. Owen & D.A. T. Harper, Department of Geo/ogy, The University, Dundee DDI 4HN, Scot/and. The Ordovician succession in Ringerike is poorly tended in conjunction with other workers to cov­ exposed and localities yielding large diverse shel­ er the Ordovician of the entire Oslo Region. The ly faunas are rare. An exception is Vestbråten present authors are mapping the Ringerike suc­ (NM65555960), some 11 km south-south-west of cession in the light of the revised terminology Hønefoss. Although the present surface outcrop and here name the unit containing the rocks at is very restricted, the collections in the Paleonto­ Vestbråten, the Norderhov Formation. The for­ logisk Museum, Oslo from here comprise one of mation comprises a few tens of metres of green­ the !argest samples from a single locality in the grey calcareous shales with subsidiary limestone Ordovician of the whole Oslo Region. The richly nodules and its stratotype is designated as being fossiliferous shales and limestone lenses at Vest­ at Norderhov (NM71106655).
