Just out @ BMC Evolutionary Biology Further study of Late Devonian seed plant Cosmosperma polyloba: its reconstruction and evolutionary significance Author(s) Le Liu, Deming Wang, Meicen Meng and Jinzhuang Xue Abstract: Background The earliest seed plants in the Late Devonian (Famennian) are abundant and well known. However, most of them lack information regarding the frond system and reconstruction. Cosmosperma polyloba represents the first Devonian ovule in China and East Asia, and its cupules, isolated synangiate pollen organs and pinnules have been studied

On the News @ ABC News Title:  Ancient marine fossils preserved under a busy Canberra bridge Penny Travers Excerpt: “Thousands of people drive over a small bridge on Canberra’s Fairbairn Avenue every day, unaware that beneath it lay ancient marine fossils. The mudstone rock outcrop on Woolshed Creek contains brachiopods, trilobites, pelecypods, corals and bryozoan fossils from the Silurian geological period. The site was discovered by the father of Australian

Shi, Tae-Yoon S. Park, Jae-Ryong Oh, Horng-Sheng Mii, and Mirinae Lee Abstract: X-ray microtomography (XMT) has become a popular tool for detailed investigations of a diverse range of fossils. However, XMT has not always guaranteed a

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 @ Palaeoworld Restudy of the Early Devonian rugose coral Xystriphylloides from South China Author(s) Chang-Min Yu Abstract: Early Devonian rugose coral Xystriphylloides in South China is restudied from the perspective of its taxonomic definition, biostratigraphy, paleoecology, and implication for the Yujiang Event. The diagnostic characters of the genus are clarified and its taxonomic position is also revised. In particular the septa of Xystriphylloides are shown to be fibrous rather than trabeculate. Xystriphylloides distinctus Yu n. sp. is

Just out @ Revue de Micropaléontologie Taphonomic and palaeovegetational studies in lower Permian (Asselian-Sakmarian) deposits of Chintalapudi Area, Godavari Graben, South India Author(s) Shreya Mishra, Neerja Jha, Sukhbir Singh Gahalain Abstract: Palynomorphs from lower Permian (Asselian-Sakmarian) deposits from Chintalapudi area of Godavari Graben were used to infer palaeovegetation and palaeoenvironments through palynofacies reconstruction and taphonomic studies. The recovered palynofloral assemblage is dominated by Cordaites with subordinate conifers and glossopterids forming the floral canopy. Fillicopsids, equisetopsids,
