Although the vertebrates received considerable attention, the Atlantic Geoscience Society pterygotids at the Natural History Museum, London are described here for the first time. The first pterygotid specimens collected in 1881 by the Geological ISSN Survey of Canada were later identified by Clarke and Ruedemann in 1912 as Pterygotus atlanticus, although they suggested it might be a variant of 0843-5561 (print) Pterygotus anglicus Agassiz. An almost complete pterygotid recovered in 1994 1718-7885 (digital) from the Campbellton Formation at a new locality in Atholville, less than two kilometres west of Campbellton, has been identified as P. anglicus Agassiz.

Pterygotid taxonomy and synonymy is briefly discussed with the genera Pterygotus, Acutiramus and Jaekelopterus shown to be potential synonyms. The use of cheliceral denticulation patterns as a generic-level character is discouraged in light of variations within genera and its unsuitability as a major characteristic in the other eurypterid families.

  • Early Devonian Eurypterids with Bohemian Affinities from Catalonia (NE Spain)
    Final draft post-refereeing from Batalleria, 7, 9-21, Barcelona (1997), ISSN: 0214-7831. Early Devonian eurypterids with Bohemian affinities from Catalonia (NE Spain) Ivo Chlupáč1, Enrique Ferrer2, José Magrans3, Ramón Mañé4, Javier Sanz5 1Institute of Geology and Palaeontology, Charles University, Albertov 6, 128 43 Prague 2, Czech Republic 2 Carrer Lluís Solé Sabarís 31-B, 08850 Gavà, Spain 3 Paseig Amadeo Vives 12, 08840 Viladecans, Spain 4 Carrer Maó, 19, 4B. 08022 Barcelona, Spain 5 Facultade de Ciencias da Educación, Universidade da Coruña, Paseo de Ronda 47, 15011 A Coruña, Spain KEY WORDS - Arthropoda, Eurypterida, Pterygotidae, Lower Devonian (Lochkovian), NE Spain ABSTRACT - The sequence of early Lower Devonian (Lochkovian) strata with dominant anchimetamorphic shales of the Olorda Formation yielded numerous remains of eurypterids. These belong to the Family Pterygotidae and are represented by dominant species of Acutiramus (closely related or identical with the Bohemian species Acutiramus bohemicus and A. perneri), and rare finds of Pterygotus cf. barrandei. The eurypterids are typical components of a purely marine assemblage of the offshore, probably open shelf environment of Benthic Assemblage 4 to 5. The clearly expressed Bohemian affinity points to open migration routes along the northern Gondwana shelves between Bohemia and Catalonia during the early Devonian, particularly Lochkovian time. RESUMEN - Las pizarras de la Formación Olorda del Devónico Inferior (Lochkoviense) contienen numerosos restos de euriptéridos. Dichos fósiles pertenecen a la Familia Pterygotidae y corresponden en su mayor parte a especies de Acutiramus, mientras son más escasos los hallazgos de Pterygotus cf. barrandei. Los restos de Acutiramus son identificados como próximos o idénticos a las especies de Bohemia, Acutiramus bohemicus and A.

    1 A summary list of fossil spiders and their relatives compiled by Jason A. Dunlop (Berlin), David Penney (Manchester) & Denise Jekel (Berlin) with additional contributions from Lyall I. Anderson, Simon J. Braddy, James C. Lamsdell, Paul A. Selden & O. Erik Tetlie Suggested citation: Dunlop, J. A., Penney, D. & Jekel, D. 2013. A summary list of fossil spiders and their relatives. In Platnick, N. I. (ed.) The world spider catalog, version 13.5 American Museum of Natural History, online at http://research.amnh.org/entomology/spiders/catalog/index.html Last updated: 12.12.2012 INTRODUCTION Fossil spiders have not been fully cataloged since Bonnet’s Bibliographia Araneorum and are not included in the current Catalog. Since Bonnet’s time there has been considerable progress in our understanding of the fossil record of spiders – and other arachnids – and numerous new taxa have been described. For an overview see Dunlop & Penney (2012). Spiders remain the single largest fossil group, but our aim here is to offer a summary list of all fossil Chelicerata in their current systematic position; as a first step towards the eventual goal of combining fossil and Recent data within a single arachnological resource. To integrate our data as smoothly as possible with standards used for living spiders, our list for Araneae follows the names and sequence of families adopted in the Platnick Catalog. For this reason some of the family groups proposed in Wunderlich’s (2004, 2008, 2012) monographs of amber and copal spiders are not reflected here, and we encourage the reader to consult these studies for details and alternative opinions.

They were more like the cousins of modern scorpions. An exceptional part of the sea scorpion evolutionary story is how they fit into the narrative of Paleozoic gigantism.

Before extinction knocked dinosaurs off their pillar, before the "Great Dying" extinction wiped out 95% of all organisms—we had the Paleozoic Era. During this age in Earth's history, between 541 million and 252 million years ago, arthropods (animals with exoskeletons such as insects, crustaceans, scorpions, and horseshoe crabs) were exploring the extremes of size, from tiny to huge. In fact, some Paleozoic arthropods represent the largest animals on Earth at the time.

  • Angustidontus, a Late Devonian Pelagic Predatory Crustacean W
    Transactions of the Royal Society of Edinburgh: Earth Sciences, 97, 75–96, 2006 Angustidontus, a Late Devonian pelagic predatory crustacean W. D. Ian Rolfe and Jerzy Dzik ABSTRACT: Restoration of the morphology of Angustidontus seriatus Cooper, 1936 based on complete specimens from the Famennian of Nevada and Poland, supports its affinity to the coeval alleged decapod Palaeopalaemon and suggests eocarid (possibly also peracarid) affinities. Predatory adaptation of the thoracopods and the relatively short pereion make this crustacean only super- ficially resemble the archaeostomatopod hoplocarids, because the large grasping appendages of Angustidontus represent the first, rather than second, maxillipeds and acted in the opposite direction: downward. Another similar adaptation of the antennae in the Vise´an Palaemysis suggests a widespread adaptation to predation among early eumalacostracans. The large sample collected from the Woodruff Formation of Nevada permits biometric characterisation of the grasping maxillipeds of Angustidontus, showing that their highly variable morphology should not be used to define species. All previously described species are therefore here synonymised with A. seriatus.Differences in gnathobases of mandibles found in articulated specimens in Nevada, and associated with isolated maxillipeds and articulated specimens possibly representing another unnamed species in Poland, suggest that such mandibles may eventually prove to be taxonomically more significant.

  • The Early Devonian Eurypterid Grossopterus Overathi (Gross, 1933) from Overath, Germany
    Mitt. Mus. Nat.kd. Berl., Geowiss. Reihe 5 (2002) 93-104 10.11.2002 The Early Devonian eurypterid Grossopterus overathi (Gross, 1933) from Overath, Germany Jason A. Dunlopl, Simon J. Braddy2 & Erik Tetlie2 With 6 figures Abstract The holotype and only known specimen of the eurypterid (Chelicerata: Eurypterida) Grossopterus overathi (Gross, 1933) from the Early Devonian (Siegennian) of Overath, north-west Germany is redescribed. Based on comparisons with other eurypterid taxa we interpret G. overathi as having a well-preserved type B genital appendage, which exhibits two apomorphic character states: (1) a furca fused into a single, spatulate plate and (2) marginal serrations near the distal end of the appendage. Grossop- terus is assigned to the family Hughmilleriidae, but its carapace resembles that of the larger Slimoniu acuminatu (Salter, 1856) (Slimoniidae). A provisional phylogenetic analysis resolves Grossopterus as the sister group of (Slimonia + Pterygotoidea). The large pterygotids, in particular, have been suggested as significant predators on early vertebrates and hypotheses about eurypterid-fish co-evolution are reviewed, in particular Romer’s proposal that dermal annour in fish evolved in response to eurypterid predation. Key words: Devonian, north-west Germany, Overath, Eurypterida, Grossopterus, Genital appendage, fish, co-evolution. Zusammenfassung Der Holotyp - das einzig bekannte Exemplar - des Eurypteriden (Chelicerata: Eurypterida) Grossopterus overathi (Gross, 1933) aus dem friihen Devon (Siegennian) von Overath im nordwestlichen Deutschland wird wieder beschrieben. Basierend auf Vergleichen mit anderen Eurypteriden-Taxa interpretieren wir G. overathi als Trager eines Typ B-Anhanges, wobei zwei apomorphe Merkmalszustande vorliegen: (1) die Furca ist zu einer einzigen, spatelformigen Platte verschmolzen, und (2) der Seitenrand nahe des distalen Endes des Genitalanhanges ist gezahnt.
