Just out @ PalZ Goniatites sphaericus (Sowerby, 1814), the archetype of Palaeozoic ammonoids: a case of decreasing phenotypic variation through ontogeny Author(s) Dieter Korn Abstract: The Late Viséan (Early Carboniferous) ammonoid species Goniatites sphaericus (Sowerby, 1814) is revised with the use of the type material. With respect to conch morphology, suture line and particularly shell ornament, it is regarded as a senior synonym of the species Goniatites fimbriatus (Foord and Crick, 1897) and must therefore be re-established as

Scientists from the Museum of Comparative Zoology at Harvard University are on the hunt for some special fossils that haven’t been located anywhere else in the world, other than Scotland. Dr. Stephanie Pierce, curator of vertebrate paleontology, brought a team of three

Just out @ Journal of Vertebrate Paleontology A Pennsylvanian ‘supershark’ from Texas Author(s) John G. Maisey, Allison W. Bronson, Robert R. Williams & Mark Mckinzie Abstract: The occipital regions of the braincases of two gigantic ctenacanthiform sharks are described from the Finis Shale (Virgilian, Upper Pennsylvanian, ca. 300 Ma) of Texas. Their original braincase lengths are estimated to have been 42.8–68.2 and 33.9–64.8 cm, based on comparison with smaller, more complete ctenacanthiform specimens (e.g., Tamiobatis). In complete

Just out @ PalZ Palaxius salataensis Brönnimann, Cros and Zaninetti, 1972, the oldest crustacean microcoprolite from the early Carboniferous of Guangxi, South China Author(s) Baba Senowbari-Daryan, Amro Gad El Rab, Katrin Heindel, Eberhard Gischler, Jörn Peckmann Abstract: Palaxius salataensis Brönnimann, Cros and Zaninetti, 1972 is described from early Carboniferous stromatolite mounds of a fore-reef slope setting from Laibin, Guangxi, South China. This is the oldest occurrence of internally structured crustacean coprolites. The geographic distribution and stratigraphic range of the ichnospecies as well as paleoecological implications

Just out @ Earth-Science Reviews Ecological changes in Pennsylvanian (Asturian and early Cantabrian) coal floras inferred from lycophyte microspore abundances Author(s) B.A. Thomasa, T.K. Dimitrova Abstract: The distribution and relative amounts of six genera of lycophyte microspores, Lycospora, Densosporites, Crassispora, Cirratriradites, Endosporites and Cadiospora, are compared in the Pennsylvanian coals from the Dobrudzha and Forest of Dean coalfields, clastic sediments from the Glace Bay borehole in the Cape Breton Coalfield, and

Just out @ Proceedings of the Geologists’ Association Testing hypotheses of element loss and instability in the apparatus composition of complex conodonts: articulated skeletons of Hindeodus Author(s) Christopher J. Cleal Abstract: England has an exceptional range of Westphalian—Stephanian (late Bashkirian—Moscovian) fossil floras spanning some 10 million years. They represent vegetation growing in part of a swamp that covered large areas of tropical Euramerica and which was responsible for the removal of

Just out @ Palaeobiodiversity and Palaeoenvironments Distinguishing Pennsylvanian-age lowland, extra-basinal and upland vegetation Author(s) Barry A. Thomas, Christopher J. Cleal Abstract: The palaeobotanical record associated with the coal-bearing sequences of Euramerica has historically been taken to epitomise Pennsylvanian (late Carboniferous) vegetation. However, both the macrofloral and the palynological record reveals a much more complex picture of low-latitude vegetational habitats of this age. Many of these other vegetation types have been traditionally
