Was Sue the T Rex pregnant?
The results confirmed those from the 2005 study, that the T. rex had medullary bone and was likely pregnant when she died, Schweitzer said. “This analysis allows us to determine the gender of this fossil, and gives us a window into the evolution of egg laying in modern birds,” Schweitzer said in a statement.

Why was the extinction of the dinosaurs bad for the Earth?
That was really bad for the planet. The dust blocked sunlight, making the planet very cold and dark. Then, over time, the gases trapped heat, causing the Earth to get even hotter than it was before the asteroid hit. This change was deadly for most dinosaurs, and they became extinct. But birds survived.
Why did dinosaurs grow as big as they did?
As it turns out, the oxygen levels at the time of the dinosaurs were actually very similar to those of today, and lower than they were during the Carboniferous period (about 300 million years ago), when giant bugs took to the skies thanks to an abundance of atmospheric oxygen. How Did Dinosaurs Grow So Large?
How big was the biggest dinosaur in the world?
The same thing would have been true of the largest dinosaurs, within the sauropod family, which could reach weights up 45 tons. However, dinosaurs did not have the same respiratory system that mammals do.
