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.
The specific name honours Mary Higby Schweitzer, one of the founders of the application of molecular biology in paleontology. [1] The holotype, IVPP V25371, was found in a layer of the lower-middle Xiagou Formation. It consists of a partial skeleton lacking the skull, compressed on a single plate. It conserves the rear half of the body.
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.
Concurrently, a line of work led by Mary Higby Schweitzer, Jack Horner, and colleagues reported various occurrences of preserved soft tissues and proteins within dinosaur bone fossils. Various mineralized structures that likely represented red blood cells and collagen fibres had been found by Schweitzer and others in tyrannosaurid bones as ...

In the March 2005 issue of Science, Dr. Mary Higby Schweitzer and her team announced the discovery of flexible material resembling actual soft tissue inside a 68-million-year-old Tyrannosaurus rex leg bone of specimen MOR 1125 from the Hell Creek Formation in Montana.
What other pictures of parts of the T Rex to upload. I have the front arms/claws, the feet, the backbone and tail, and more (bigger) pictures of the skull. Any bigger pictures of the skull will show the armature which is holding up the fossil bones. Any requests? As you can see, the Field Museum has the holiday decorations up.
