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

Just out @ Palaeontology Brachiopods: origin and early history Author(s) David A. T. Harper, Leonid E. Popov, Lars E. Holmer Abstract: Despite many major advances in recent years, three key challenges remain in bringing clarity to the early history of the phylum: (1) identifying the origin, morphology and life modes of the first brachiopods; (2) understanding the relationships of the major groups to each other and higher sister taxa; and (3)

Yan, Rolf G. Beutel, and Alexander G. Ponomarenko Abstract: †Ademosynidae is a controversial extinct family of Coleoptera, first discovered in Australian Upper-Triassic deposits. The last known representative is known from the Early Jurassic of Kirghizstan. Type material from the collection of Moscow Paleontological Institute

Just out @ Palaeontology Endo- and epilithic faunal succession in a Pliocene–Pleistocene cave on Rhodes, Greece: record of a transgression Author(s) Margret Steinthorsdottir, Eckart Håkansson Abstract: A fossil cave and associated sediments and fossil fauna located on the Greek island of Rhodes in the eastern Aegean Sea is reported here, and the depositional history discussed. The sediments were deposited during the late Pliocene, in the interstitial space between basement boulders of

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

They consist of thousands of aggregated caddisfly larval cases that are generally vertically oriented and parallel to each other. These cases are similar in size, 12–14 mm
