[Proceedings of the 5th Symposium on Mesozoic and Cenozoic Decapod Crustaceans, Krakow, Poland, 2013: A tribute to Pál Mihály Müller / R.H.B. Fraaije, M. Hyžný, J.W.M. Jagt, M. Krobicki &amp; B.W.M. van Bakel (eds.)]: Neozanthopsis americana (Decapoda, Brachyura, Carpilioidea) from the Middle Eocene Cane River Formation of Louisiana, USA, and associated teleost otoliths

A large collection of Neozanthopsis americana (Rathbun, 1928) from the Middle Eocene (Lutetian) Cane River Formation in Louisiana, USA, represents the first opportunity to describe the species in detail. Detailed analysis of associated teleost otoliths and other vertebrate remains documents a palaeoenvironmental setting characterised by a soft-sediment, inner-shelf setting with normal salinity under tropical or subtropical conditions. Anatomical and morphometric analysis of 21 of the better-preserved crabs demonstrates that gender discrimination cannot be made from dorsal carapace characteristics and that the sample represents post-juvenile individuals. Exocuticle and endocuticle are preserved on some specimens and document the presence of erect...

The present record of two species of brachyurous decapod crustaceans, Costacopluma grayi Feldmann &amp; Portell, 2007 and Stevea martini sp. nov., from the lower Paleocene Pine Barren Member (Clayton Formation) in south-central Alabama, constitutes an extension of the range of the former and the sole occurrence of the latter. Previously, C. grayi was described from the middle Eocene Tallahatta Formation in Alabama. Stevea martini sp. nov. constitutes only the second species of the genus and the sole fossil occurrence known to date.

A new family of brachyuran (Crustacea: Decapoda: Goneplacoidea) from the Eocene of Java, Indonesia
Provedor de dados: 16
Autores: Schweitzer, C.E.; Feldmann, R.M.; Bonadio, C.
A new family, Martinocarcinidae, must accommodate the monotypic genus Martinocarcinus Böhm, 1922. The genus displays a unique combination of dorsal, sternal and abdominal characters justifying placement in a new family. The Martinocarcinidae joins several other now extinct Eocene families that flourished at that time, supporting the long-held view that the Eocene was a time of radiation within the Brachyura.

A new classification of the Xanthoidea sensu lato (Crustacea: Decapoda: Brachyura) based on phylogenetic analysis and traditional systematics and evaluation of all fossil Xanthoidea sensu lato
Provedor de dados: 16
Autores: Karasawa, H.; Schweitzer, C.E.
A phylogenetic analysis was conducted including representatives from all recognized extant and extinct families of the Xanthoidea sensu lato, resulting in one new family, Hypothalassiidae. Four xanthoid families are elevated to superfamily status, resulting in Carpilioidea, Pilumnoidoidea, Eriphioidea, Progeryonoidea, and Goneplacoidea, and numerous subfamilies are elevated to family status. The Mathildellidae is moved from the Goneplacidae to the Portunoidea. Diagnoses for all superfamilies and families discussed herein are provided, embracing characters typically used by biologists as well as readily fossilized features of the dorsal carapace, sternum, abdomen, and chelipeds. All genera known from the fossil record at one time referred to the Xanthidae...
