Paleontology Research Group from North Carolina Museum of Natural Sciences, USA have found a mother T-Rex with its baby-eggs in its belly! Their further femur testing has confirmed that the existence of medullary bone in its fossil. Whichbone could only exist in a Female T-Rex that was about lay eggs or were laying eggs.
The pregnant T-Rex was found in Montana. Talking about oldest mother, it is dated 68 million years old. Professor Lindsay Zanno of North Carolina State University, told that medullary bone only exists when a dinosaur or a bird was to lay eggs soon. Unlike Crocodiles, the closest being to dinosaur, who suffer from calcium deficiency from their bones while laying eggs. It was Mary Schweitzer of their team who firstsuspected this from the fossil. chemical analysis confirmed the trace of KeratanSulfate that is only found in medullary tissues.
There is a big possibility for the medullary bone to have preserved some DNA in there.This could be a huge breakthrough in understanding the egg laying evolution of modern birds and more about the biological nature of dinosaurs. huge corporation might even fund it and build Jurassic Park!
