Carnegie Museum of Natural History paleontologist Chris Beard says by studying the evolution of prehistoric animals, today's medical students can understand the origins of some common medical problems.

"This is, as far as we know, the oldest evidence of cancer in the fossil record," he tells DBIS of a softball-sized tumor in a 150-million-year-old dinosaur bone.

Paleontologists learned this is a special kind of cancer called osteosarcoma that, in humans, can develop during a teenage growth spurt.

Beard says these are examples that med students are unlikely to forget. "I think that it'll make them better physicians just in the sense of being able to diagnose a potential osteosarcoma at an early stage," he says. "They'll be more ready to look out for it, just knowing and being exposed to this dramatic example in the past." ...Mysteries from the past, unraveled by research and delicate work in the present.
