| Bite marks on face reveal Tyrannosaurus "the price of love" |
When animals fight each other for spouse, territory and status, the most impressive scene in nature occurs
.
Now, scientists have evidence that dinosaurs like Tyrannosaurus do the same, and bit their opponents in the process
The researchers analyzed 528 theropod skull fossils, 122 of which had deep bite marks and healing injuries
.
Researchers recently reported in Paleontology that these traces appeared on approximately 60% of adult animals, but did not appear on any young animals
The researchers also examined the skulls of small dinosaurs, which are the origin of all birds today
.
They have no bite marks, which suggests that, like their offspring birds, these animals may no longer fight fiercely for mates, but start courting with their shiny feathers
