Just out @ Bulletin of Geosciences Early Ordovician black corals from China Author(s) Baliński A, Sun Y Abstract: Despite the importance of black corals in modern coral faunas and marine ecosystems, they were unknown in the fossil record until the recent discovery of abundant phosphatised remains in the Lower Ordovician Fenxiang Formation in the Three Gorges area (Hubei Province) of South China. The poor fossil record of black corals could

Just out @ Palaeontologia Electronica RNames, a stratigraphical database designed for the statistical analysis of fossil occurrences – the Ordovician diversification as a case study Author(s) Björn Kröger and Kari Lintulaakso Abstract: Names (rnames.luomus.fi/) is an open access relational database linking stratigraphic units with each other that are considered to be time-equivalent or time overlapping. RNames is also a tool to correlate among stratigraphic units. The structure of the database

This conodont fauna is composed of Ansella sp., Belodina

Just out @ PeerJ Title:  Halkieriid-like animals in the Late Ordovician? Author(s) Dawid Mazurek Abstract: The recent description of the Tremadocian halkieriid-like stem aculiferan, Calvapilosa kroegeri, could shed new light on some enigmatic Ordovician fossils known only by their disarticulated plates. Specifically, Conchopeltis alternata could be interpreted as a plate of sclerite-bearing stem aculiferan. Comparison is based on a similarity of conchs and reinterpretation of Conchopeltis tentacles as sclerites. This

Trilobite's eggs (or Thomas and Markus's 'Eureka!' moment)

In the previous three weeks, trilobites (those beloved paleozoic arthropods) have taken the paleontological front stage, yet once more. The discovery of what is believed to be the first record of trilobite eggs and with it, the suggestion of a possible mechanism of reproduction, was then brought to the general public and sparked considerable enthusiasm and commotion. Well, sadly, the parody by Glendon Mellow (see image below) was just that:
