Good ribbance: U of T researcher finds dino rib bones reveal remnants of 195-million-year-old protein
“These dinosaur proteins are more than 100 million years older than anything previously discovered,” says Professor Robert Reisz, a specialist in vertebrate paleontology in the department of biology at U of T Mississauga. “These proteins are the building blocks of animal soft tissues, and it’s exciting to understand how they have been preserved.”
