Mary Higby Schweitzer is an American paleontologist at North Carolina State University, who led the groups that discovered the remains of blood cells in dinosaur fossils and later discovered soft tissue remains in the Tyrannosaurus rex specimen MOR 1125, [1] [2] as well as evidence that the specimen was a pregnant female when she died.
In 2016, it was finally confirmed by Mary Higby Schweitzer and Lindsay Zanno et al that the soft tissue was medullary bone tissue, like that in modern birds when they are readying to lay eggs. This confirmed the identity of the Tyrannosaurus MOR 1125 as a female.
