    The T-rex, which was found in Montana and dates back 68 million years, retained medullary bone revealing the individual was pregnant. Medullary bone is only present in female birds — which are related to dinosaurs — just before and during egg-laying. It is this type of bone that could retain preserved DNA.
    This discovery will shed light on the evolution of egg-laying as well as on gender differences in the dinosaur.
