On the News @ Los Angeles Magazine Title:  La Brea Tar Pits Museum Bracing for a Flood of Fossils This Summer Matthew Segal Excerpt: “The La Brea Tar Pits know no mercy. The world’s most productive urban paleontological dig, they’ve yielded a stockpile of fossils that spill over from the main galleries of the La Brea Tar Pits Museum and into the lab and the cabinets and lockers that line

Julia Sankey and Jacob Biewer (California State University) just released “The Giant Spike-Toothed Salmon and Other Extinct Wildlife of Central California”, a new book on the giant, spike toothed salmon and massive tortoises in California. Written for a general audience, with excellent illustrations, the book is readly available through Amazon. It portrays the California of 5 million years ago and the very weird animals inhabiting it. Go back in time and learn about

Just out @ Geology A Laurentian record of the earliest fossil eukaryotes Author(s) Zachary R. Adam, Mark L. Skidmore, David W. Mogk and Nicholas J. Butterfield Abstract: The oldest evidence of eukaryotes in the fossil record comes from a recurrent assemblage of morphologically differentiated late Paleoproterozoic to early Mesoproterozoic microfossils. Although widely distributed, the principal constituents of this Tappania–Dictyosphaera–Valeria assemblage have not hitherto been recognized on Laurentia. We have recovered all three taxa from

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

Just out @ Journal of Vertebrate Paleontology Additions to the Lancian mammalian fauna from southwest North Dakota Author(s) Clint A. Boyd, Jeff J. 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

Just out @ Journal of Vertebrate Paleontology The Gobiosuchidae in the early evolution of Crocodyliformes Author(s) Ángela D. Buscalioni Abstract: The anatomy and phylogenetic relationships of the Las Hoyas gobiosuchid (upper Barremian, La Huérguina Formation, Cuenca, Spain) are discussed on the basis of two fully articulated specimens. Phylogenetic analysis supports the monophyly of Gobiosuchidae, defined by the Las Hoyas taxon, Cassissuchus sanziuami, gen. et sp. nov., as the sister taxon of the

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

On the News @ Smithsonian.com Title:  Scientists Are Putting Tens of Thousands of Sea Fossils Online Erin Blakemore Excerpt: “Some 100 million years ago, much of what is now North America was underwater. The body of water scientists call the Western Interior Seaway covered a swath of land that stretched over the entire Midwest. But its secrets have been preserved in countless fossils—and now, over 100,000 of these fossils are being digitized.
