At the starting period of dinosaurs, huge reptiles controlled the world. They lived on Earth as well as on water. However, it was believed that they did not communicate that much with each other.
Recently, UT researchers unearthed a tooth which was present in the thigh of one of these ancient animals. This discovery puts a question mark on all the previous scientific speculations.
Stephine Drumheller, who is an earth and planetary professor along with her colleagues, analyzed 220 million year old bit mark in the thigh bones of an old reptile. The examination revealed that two predators among which one was smaller and the other was larger fought and killed each other.
The tooth was hidden two inches deep in a wound that was present inside the bone of that animal. This depth of tooth signifies that the animal got injured badly during that battle but somehow survived.
The panel joined with computed tomographic data with a 3D printer in order to examine the tooth without causing any damage to the bone of that animal. Later on, the team closely studied the printed copies of that tooth.
In this extensive study, the team discovered a tissue covered with multiple bite marks. These bite marks demonstrated that the rauisuchid was assaulted more than one time. Numerous evidences of crushing and tearing of flesh were observed.
However, the end result of the study showed that there used to be some kind of interaction between the dinosaurs of water and dinosaurs of land. The study revealed that all the earlier speculations were wrong about the interaction of the two species.
