Scientists have struggled through the years to find a fossil of a pregnant Tyrannosaurus Rex and to distinguish between males and females. However, they may have finally found their answer.
According to CNN, scientists have determined that a certain T-Rex fossil found in Montana was female. “The researchers from North Carolina State University and the North Carolina Museum of Natural Sciences found a medullary bone in a T-Rex femur.”
The medullary bone is pretty much bone marrow that is only found in female birds before or during their egg-laying period.
It will now be easier for scientists to determine the differences between male and female theropodous dinosaurs. I guess we’ll all be learning more about the T-Rex in the future.
