  • 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.

    The Palaeontological Association 63rd Annual Meeting 15th–21st December 2019 University of Valencia, Spain PROGRAMME ABSTRACTS AGM papers Palaeontological Association 6 ANNUAL MEETING ANNUAL MEETING Palaeontological Association 1 The Palaeontological Association 63rd Annual Meeting 15th–21st December 2019 University of Valencia The programme and abstracts for the 63rd Annual Meeting of the Palaeontological Association are provided after the following information and summary of the meeting. An easy-to-navigate pocket guide to the Meeting is also available to delegates. Venue The Annual Meeting will take place in the faculties of Philosophy and Philology on the Blasco Ibañez Campus of the University of Valencia. The Symposium will take place in the Salon Actos Manuel Sanchis Guarner in the Faculty of Philology. The main meeting will take place in this and a nearby lecture theatre (Salon Actos, Faculty of Philosophy). There is a Metro stop just a few metres from the campus that connects with the centre of the city in 5-10 minutes (Line 3-Facultats). Alternatively, the campus is a 20-25 minute walk from the ‘old town’. Registration Registration will be possible before and during the Symposium at the entrance to the Salon Actos in the Faculty of Philosophy. During the main meeting the registration desk will continue to be available in the Faculty of Philosophy. Oral Presentations All speakers (apart from the symposium speakers) have been allocated 15 minutes. It is therefore expected that you prepare to speak for no more than 12 minutes to allow time for questions and switching between presenters. We have a number of parallel sessions in nearby lecture theatres so timing will be especially important.

    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.

    Introduction to the Trilobites: Morphology, Ecology, Macroevolution and More By Michelle M. Casey1, Perry Kennard2, and Bruce S. Lieberman1, 3 1Biodiversity Institute, University of Kansas, Lawrence, KS, 66045, 2Earth Science Teacher, Southwest Middle School, USD497, and 3Department of Ecology and Evolutionary Biology, University of Kansas, Lawrence, KS 66045 Middle level laboratory exercise for Earth or General Science; supported provided by National Science Foundation (NSF) grants DEB-1256993 and EF-1206757. Learning Goals and Pedagogy This lab is designed for middle level General Science or Earth Science classes. The learning goals for this lab are the following: 1) to familiarize students with the anatomy and terminology relating to trilobites; 2) to give students experience identifying morphologic structures on real fossil specimens 3) to highlight major events or trends in the evolutionary history and ecology of the Trilobita; and 4) to expose students to the study of macroevolution in the fossil record using trilobites as a case study. Introduction to the Trilobites The Trilobites are an extinct subphylum of the Arthropoda (the most diverse phylum on earth with nearly a million species described). Arthropoda also contains all fossil and living crustaceans, spiders, and insects as well as several other extinct groups. The trilobites were an extremely important and diverse type of marine invertebrates that lived during the Paleozoic Era. They only lived in the oceans but occurred in all types of marine environments, and ranged in size from less than a centimeter to almost a meter across. They were once one of the most successful of all animal groups and in certain fossil deposits, especially in the Cambrian, Ordovician, and Devonian periods, they are extremely abundant.

Shales of the Šárka Formation exposed in the excavation on Červený vrch Hill at Praha-Vokovice contain a common but monotonous assem- blage of phyllocarids associated with other extremely rare arthropods. Almost all trilobite remains (genera Ectillaenus Salter, 1867, Placoparia Hawle et Corda, 1847 and Asaphidae indet.) occur in a single horizon of siliceous nodules of stratigraphically uncertain position, while the surprising occurrence of possible naraoid trilobite (Pseudonaraoia hammanni gen. n., sp. n.) comes from dark grey shales. The general character of the arthropod assemblage char- acterized by an expressive dominance of planktonic and/or epi-planktonic elements (phyllocarids) indicates a specific life environment (most probably due to poor oxygenation). This association corresponds to the assemblage preceding the Euorthisina-Placoparia Community sensu Havlíček and Vaněk (1990) in the lower portion of the Šárka Formation.

    Introduction to the Trilobites: Morphology, Macroevolution and More By Michelle M. Casey1 and Bruce S. Lieberman1,2, 1Biodiversity Institute and 2Department of Ecology and Evolutionary Biology, University of Kansas, Lawrence, KS 66045 Undergraduate laboratory exercise for sophomore/junior level paleontology course Learning Goals and Pedagogy This lab is intended for an upper level paleontology course containing sophomores and juniors who have already taken historical geology or its equivalent; however it may be suitable for introductory biology or geology students familiar with geological time, phylogenies, and trace fossils. This lab will be particularly helpful to those institutions that lack a large teaching collection by providing color photographs of museum specimens. Students may find previous exposure to phylogenetic methods and terminology helpful in completing this laboratory exercise. The learning goals for this lab are the following: 1) to familiarize students with the anatomy and terminology relating to trilobites; 2) to give students experience identifying morphologic structures on real fossil specimens, not just diagrammatic representations; 3) to highlight major events or trends in the evolutionary history and ecology of Trilobita; and 4) to expose students to the study of macroevolution in the fossil record using trilobites as a case study. Introduction to the Trilobites The Trilobites are an extinct subphylum of the Arthropoda (the most diverse phylum on earth with nearly a million species described). Arthropoda also contains all fossil and living crustaceans, spiders, and insects as well as several other solely extinct groups. The trilobites were an extremely important and diverse type of marine invertebrates that lived during the Paleozoic Era. They were exclusively marine but occurred in all types of marine environments, and ranged in size from less than a centimeter to almost a meter.

Estos han sido descritos con detalle en diversos estudios (HAMMANN, 1971, 1974), donde se comprobó el interés bioestratigráfico que presentan las es- pecies del género Placoparia HAWLE y CORDA, 1847. A conclusiones similares llegaron las investigaciones llevadas a cabo en sucesiones comparables de la Zona Centroibérica portuguesa y el Macizo Armo- ricano francés (HENRY y CLARK5ON, 1975; ROMANO, 1976; HENRY, 1980).
