Our museum is part of the University's fund-drive: pardon the NPR-style interruption, but consider donating if you want to support public science. Wonderful donors are matching gifts, so it's a great chance to help us keep connecting the public with natural history. go.unl.edu/unsmglowbigred

Ever wonder how you can tell a dinosaur’s age? In a new study establishing Nanotyrannus as a species, researchers cross-sectioned slices of its hyoid to gauge maturity and understand how quickly it grew. Read more about the brand new discovery here: nhm.org/new-nanotyra...

#FossilFriday visiting some old friends! This was the first turtle shell I collected, it is a pelomedusoid from the early #Oligocene Juana Diaz Fm. in southwestern #PuertoRico. Pelomedusoids are found in shallow marine deposits across the #GreaterAntilles until the Pliocene. #CaribbeanPaleobiology

Hi! We need lice for our diversity and adaptation project. Specifically, we need lice from zebras, camelids (camels, llamas, alpacas, vicuñas, guanacos) & aardvarks. If you or someone you know might have lice, I'm happy to discuss our inclusive collaboration plans! sites.google.com/nhm.org/anop...

NEWLY PUBLISHED » Dr. Jorge Velez-Juarbe (Associate Curator, Marine Mammals) discovers that sebicids, ancient land-dwelling crocodile-like beasts, reigned over the West Indies as apex predators after vanishing from South America: bit.ly/AncientCrocs

A fossil tooth and two vertebrae unearthed in the Dominican Republic have paleontologists rethinking sebecids, giant croclike terrestrial predators, and their story in the Caribbean. Story: www.floridamuseum.ufl.edu/science/gian... Study: doi.org/10.1098/rspb...

Our new paper, published today in @royalsociety.org Proceedings B, documents the presence of #sebecids in the #GreaterAntilles from the early #Oligocene through the early #Pliocene. Sebecids were apex-predator crocodylomorphs adapted to life on land. #CaribbeanPaleobiology 1/11

Oh groovy, our paper on the hindlimb biomechanics of the Triassic dinosauriform Lagosuchus is out! A quick thread for now. We uCT-scanned most of the existing skeletal material for this important outgroup to Dinosauria. We sorted through the elements and chose the best ones to make a 3D model from.
