Novel report of an osteogenic tumor in a late Jurassic Mamenchisaurid from Thailand
Here we describe a pathology in an ulna of a Late Jurassic mamenchisaurid from Thailand. We use anatomical descriptions, CT scanning, and bone histology to identify the pathology as an osteogenic tumor. Abstract Here we report on an osseous abnormality and multiple fractures in an ulna of a subadult basal Eusauropod (Mamenchisauridae) from the Late ...

Abstract Ornithopoda is one of the three main ornithischian dinosaur clades in which secondary quadrupedality is represented. However, when it evolved from obligate bipedality remains controversial. Indeed, the ability to alternate between the two habits was inferred in some ornithopods based on ichnological observations and a mosaic of bipedal and ...

Abstract Thescelosaurines are a group of early diverging, ornithischian dinosaurs notable for their conservative bauplans and mosaic of primitive features. Although abundant within the latest Cretaceous ecosystems of North America, their record is poor to absent in earlier assemblages, leaving a large gap in our understanding of their evolution ...

Illustration of the endocranial doming, which can provide a proxy for the brain‐to‐endocranial cavity index, using the endocast of an adult of the iguanodont dinosaur Proa valdearinnoensis as an example. Abstract Although the brain fills nearly the entire cranial cavity in birds, it can occupy a small portion of it in crocodilians.
