It lived through a time once the area was covered in forests and braided rivers, and would have had to watch out to the existence of Sarcosuchus, an enormous relative of contemporary crocodiles.

The decrease jaw was L-formed and divided in the subcylindrical transverse ramus, which contained the teeth, along with the back again ramus, which was more lightweight and was the location for a lot of the muscle mass attachments. It had been distinctive in that the tooth row expanded to the sides through the plane of the main ramus in the decrease jaw.

This framework was among the primary dinosaur skulls to be digitally reconstructed employing CT scans, providing unparalleled insights into its feeding mechanics.
We thoroughly brushed the sand from the one hundred ten million-yr-old bones and dug channels in between the foremost parts of the skeleton. Shortly We are going to protect Every single area in plaster so which the skeleton is often transported outside of the sphere and again to your laboratory.
