Just out @ Cretaceous Research Microbial–caddisfly bioherms in the Early Cretaceous Yixian Formation in the Yixian Basin, Western Liaoning, China Author(s) Enpu Gong, Jiang Xu, Tiehui Wang, Yue Liang, Fei Gao Abstract: Microbial–caddisfly bioherms have recently been discovered in the Early Cretaceous Yixian Formation in Western Liaoning, China. 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

The Aitamir Formation represents a graded siliciclastic shelf system and the turrilitid faunas comprise

Just out @ Proceedings of the Geologists’ Association A revision of some British Lower Bajocian stephanoceratid ammonites Author(s) Robert B. Chandler, Volker Dietze, John Whicher Abstract: Members of the ammonite family Stephanoceratidae from the Middle Jurassic, Lower Bajocian, Laeviuscula to Humphriesianum zones of South West England are revised. These comprise faunas resulting from periodic migrations and possibly hybridization. The taxonomic positions of TelocerasMascke, 1907, Kumatostephanus Buckman, 1922, Gibbistephanus Buckman, 1928 and Pseudoteloceras Pavia and Fernández-López, 2016 are considered in the

On the News @ Montana State University Title:  MSU research resets timeline for evolution of complex life forms in North America Skip Anderson Excerpt: “A Montana State University doctoral graduate discovered fossilized microorganisms in western Montana that predate by 200 million years fossils previously believed to be the oldest complex life forms in North America. Zach Adam’s research of the fossilized remains of a eukaryote called Tappania shows that Earth’s first complex life

On the News @ The Guardian Title:  What if dinosaurs were still alive? You asked Google – here’s the answer Brian Switek Excerpt: “Dinosaurs dominated terrestrial life on this planet for over 130m years. If it hadn’t been for a wayward asteroid, the reign of Tyrannosaurus rex and its ilk could have lasted for at least another 66m. In fact, let’s presume for a moment that the cosmic boulder that ended

Walker, Ya Yang, Michael J. Moore, Jessica Mikenas, Alfonso Timoneda, Samuel F. Brockington and Stephen A. Smith Abstract: PREMISE OF STUDY: The carnivorous members of the large, hyperdiverse Caryophyllales (e.g., Venus flytrap, sundews, and Nepenthes pitcher plants) represent perhaps the oldest and most diverse lineage of carnivorous plants. However, despite numerous studies seeking to elucidate their evolutionary

Just out @ Historical Biology Origin and relationships of the Ictidosauria to non-mammalian cynodonts and mammals Author(s) José F. Bonaparte & A. W. Crompton Abstract: Ictidosaurian genera are allocated to two families, Tritheledontidae and Therioherpetidae. This paper provides a diagnosis for Ictidosauria. The previously named family Brasilodontidae is shown to be a junior synonym of a family, Therioherpetidae. It is concluded that Ictidosauria originated from Late Permian procynosuchid non-mammalian cynodonts rather than from

Person & Becky Barnes Abstract: Gaining a detailed understanding of the geographic and temporal variations between Lancian mammalian faunas within the Western Interior Basin requires specimens to be associated with precise stratigraphic data, but only a few mammal-producing localities are documented in such detail from the Hell Creek Formation of southwestern
