Here’s what came out this week in dinosaur news:
- More details from this years SVP conference (referenced abstracts can be found in the PDF from the meeting) source
- 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
