Yamaceratops - Episode 205

Dinosaur of the day Yamaceratops, a ceratopsian whose frill is heavily pitted, possibly for jaw muscle attachments.

Interview with Ali Nabavizadeh, Assistant Professor of anatomy at Cooper Medical School of Rowan University. He studies the jaw musculature of herbivorous dinosaurs. Follow him on Twitter @Vert_Anatomist and check out his blog Anatomist's Guide.

In dinosaur news this week:

• A large sauropod from the Late Cretaceous has been found in the Gobi Desert and it’s about 30-40% complete
• In Argentina 70 million year old dinosaur eggs were found possibly including embryos, skin, and teeth
• The “Tufts-Love” T. rex skull at the Burke Museum has found 100% of the skull and jaw bones by bone count including several that are rarely preserved
• Junchang Lü, one of the most prominent paleontologists in China, recently passed away at the beginning of October at the age of 53
• Chilesaurus diegosuarezi, the first Jurassic dinosaur found in Chile, is going on exhibit at the Regional Museum of Aysen, in Coyhaique, Chile, next year
• An Allosaurus will be posed with a nest at the Smithsonian National Museum of Natural History since it may have looked after its young
• Jurassic World is selling Indoraptor masks, just in time for Halloween
• A study of 150 Ceolophysis—mostly from the same bonebed—show that early triassic dinosaurs had femora that changed significantly as they aged
• The data used to support the Ornithoscelida hypothesis had many errors, which casts some doubt on the conclusion that Ornithoscelida should replace the traditional Saurischia and Ornithischia groups
• A study of a baby Massospondylus and it’s forelimb strength shows that Massospondylus was bipedal for its entire life
• A simulation of Mussaurus (the earliest Jurassic sauropodomorph) showed its center of mass shifted as it grew, meaning that it was quadrupedal as a baby and bipedal as an adult
• Researchers used a program called niche mapper to model microclimates of Plateosaurus & Coelophysis, showing which environments they would prefer based on plumage and metabolic rates
• Reconstructions of dinosaur feeding musculature shows that they chewed in a way different than any animal alive today
• A study of emu and ostrich bones found many similarities with dinosaurs and suggests using bone microstructure to identify maturity
• Sauropodomorph inner ears vary significantly across groups: Diplodocoids have relatively smaller inner ear, while Giraffatitan has the largest known inner-ear
• By studying alligator and turkey arms we might be able to show which theropods could supinate their hands as they drew them to their body
• A study of dinosaur bearing sites from Dinosaur Park Formation in Alberta & Saskatchewan and the similar aged Judith River sites in Montana shows which locations were the most similar
• A new model of dinosaur diversity in the latest cretaceous shows that they were not in decline, but instead maybe slowing down or leveling off
