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
