Dinosaur of the day Montanoceratops, a primitive ceratopsian with an unusually deep tail thanks to its vertebral spines. Interview with Ashley & Lee Hall, both from the Cleveland Museum of Natural History. Ashley is the Adult Programs Coordinator and Lee is a Preparator and Lab Manager. But more importantly, like us, their wedding heavily featured dinosaurs. In dinosaur news this week: T. rex could turn more quickly than similar dinosaurs New histology on the tyrannosaurs Jane & Petey show that Nanotyrannus is probably a juvenile T. rex Simulated jaw mechanics showed the bite force and bone penetration of several tyrannosaurs The juvenile T. rex Found N.E. Montana includes partial hands, feet, vertebrae, ribs, a partial skull, and teeth Therizinosaurs have an unusual combination of basal arm musculature and more avian style leg musculature Dinosaurs’ unique single ovary appears to have evolved after Oviraptor but before Troodontidae We don't know if large bodied dromaeosaurs (velociraptor and larger) had tail fans The new "Mtuka titanosaur" was found in Africa An analysis of fossil fragments in Mygatt-Moore showed about half of the bones had marks on them Maiasaura humeri bone microstructure changed as they aged, supporting a shift from bipedal to quadrupedal Pachycephalosaurus has theropod-like teeth in the front and other similarities to Dracorex An analysis of the pachycephalosaur Sphaerotholus showed that all 3 species should be considered valid Early dinosaurs had thin semi rigid eggs, but in the early to mid Jurassic their eggs got thicker—possibly as a solution to dehydration and predation By studying dozens of crocodilian, turtle, and bird nests, researchers found that the arrangement is preserved well as it is buried Professional fossil preparator tips include: wear gloves, use tools only after getting training, and test other methods in advance to avoid unwanted destruction High quality photogrammetry and 3D printing can be achieved using cheaper equipment It is important to standardize and clean up the large amounts of historical fossil data so that it is easy to search and understand This episode is brought to you in part by TRX Dinosaurs, which makes beautiful and realistic dinosaur sculptures, puppets, and animatronics.
