Novel report of an osteogenic tumor in a late Jurassic Mamenchisaurid from Thailand

Journal of Anatomy, EarlyView.
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 ...

Biol Rev Camb Philos Soc
ABSTRACT The long‐term effects of present‐day climate change on pollination are unquantified. However, distinguishing climatic drivers of ancient changes in pollination could provide valuable insights into biotic responses to near‐future climate states.
