Review of Pathologies on MOR 693: An Allosaurus from the Late Jurassic of Wyoming and Implications for Understanding Allosaur Immune Systems.
PaleoRxiv (preprint)
https://paleorxiv.org/f3rh6/Palaeopathology is important as it provides remarkable insights into the lifestyles of dinosaurs and other prehistoric animals. The Late Jurassic Allosaurus known as Big Al (MOR 693) from Big Horn County, Wyoming preserves at least 19 injuries. About 2% of all bones showed abnormalities, including osteomyelitis on the right foot, on the first phalanx of the third toe, which may have contributed to the animal's death. There would likely have been many more pathologies that did not make it into the paleontological record due do the lack of soft-tissue preservation. Analysis of MOR 693âs immune response to bone infections and comparing it to other theropods, we can confidently say that dinosaurs possessed an immune system that isolated and localized infections like extant Aves.
