Mary Higby Schweitzer

Mary Higby Schweitzer is a paleontologist at North Carolina State University known for leading the groups which discovered the remains of blood cells in dinosaur fossils and later discovered soft tissue remains in the Tyrannosaurus rex specimen MOR 1125, as well as evidence that the specimen was a pregnant female when she died. More recently, Schweitzer's work has shown molecular similarities in Tyrannosaurus remains and chickens, providing further evidence of the bird-dinosaur connection.
