Insight from Jonathan Geisler, Ph.D., interim dean of research at the College of Osteopathic Medicine, is featured in a magazine article about a mystery surrounding the origins of the giant extinct mammal Andrewsarchus. The skull of the creature, which appeared much like a wolf with hoof-like feet, is on display at New York City鈥檚 American Museum of Natural History. However, the limited and worn condition of the fossil complicates comparisons with other animals, as Geisler, an expert on the evolutionary history of mammals,聽notes. He shares that the skull鈥檚 damaged and altered features鈥攊ncluding worn teeth and missing inner ear bones鈥攎ake it hard to match anatomical traits with known relatives, leaving its evolutionary placement uncertain. He also suggests that similarities between Andrewsarchus and other hoofed mammals might reflect convergent evolution rather than close ancestry, highlighting how challenging it is to interpret the beast鈥檚 true nature with so little material.
