Caption: An artist's rendering of a T. rex suffering from a trichomonosis-like disease, a parasitic infection caused by a protozoan, a single-celled organism that infects the mouth and throat and may have caused the animal to starve to death, according to a study conducted by an international team of researchers led by Ewan Wolff of UW-Madison's School of Veterinary Medicine. The renderings show the infection and how it relates to the lesions found on the mandible of 'Peck's Rex' (Museum of the Rockies).
