A new titanosaur from Kenya, footprints on Tyrants Aisle, and teaching evolution through paleoart

Dinosaur of the day Coloradisaurus, a Triassic sauropodomorph known from a nearly complete skull that was found in Argentina.

Interview with Taissa Rodrigues, from the Universidade Federal do Espirito Santo in Brazil. She presented a poster at SVP about teaching evolution using paleoart. She also led a session on women in paleontology and had a student present a poster on a pterosaur. Follow her on twitter @paleotaissa

Presentations from the first day of SVP:

New dating shows Lythronax argestes is older than previously thought, no longer coinciding with a global sea-level dropThere are tons of new sauropod fossil fields in southwest Queensland, Australia, near EromangaProbable ornithopod, ceratopsid, deinonychosaur, and tyrannosaur tracks were found on a 200ft cliff in AlaskaIn Alberta, Tyrants Aisle has over 120 tracks likely belonging to Edmontosaurus, a troodontid, Tyrannosaurus, and another theropodCT scans of track slabs shows how dinosaur feet moved through soft sedimentsLaser-stimulated fluorescence (LSF) is being used to gather evidence of the first aerodynamically significant wingsA new track site shows a couple sauropods walking together when a larger sauropod skids to avoid squashing a smaller individual.New sauropod finds in Hateg island Transylvania, Romania may be a fourth genus, but isn’t complete enough to get a new nameDinosaurs and crocodiles have hard eggshells that evolved independentlyA new titanosaur was found in NW KenyaLow melanosome (color pigment producer) diversity may be linked to low metabolismCompacted coarse cancellous bone (CCCB) that is common in burrowing animals was found in the hind limbs of a new Oryctodromeus relativeExceptional fossils don’t necessarily translate to good cellular and molecular preservationNew opalized femur fragments from an ornithopod in lightening ridge show that young were born in the areaMelanosomes are not enough to determine color. Structure, chemistry, and diet also have a big impactCalcium isotopes from Morocco and Niger support Spinosaurus as a fish-eaterMore neornithischian finds from south of Melbourne may end with one or two synonymized taxa in the near futureNew research shows ovarian follicles in an enantiornithineA sauropod footprint was found in a new sauropod bone, adding to the idea of trampling sauropodsA dinosaur stampede like trackway was found near Quilpie, QLD, AustraliaCoprolites can preserve some soft tissue features and other information about temperatures and habitatsThe name Kamuysaurus is meant to mean that it is the god of Japanese dinosaurs based on its incredibly complete skeletonDeep learning can process CT scans and save time on analyzing imagesEquisetum, or horse tails, were probably the most nutritious food for young and adult sauropodsBirds use their necks in a variety of ways, but they tend to have a lot of traits in common
