Dinosaurs also fight each other, scientists find evidence in the largest triceratops fossil in history

We all know that Triceratops defended territory, fought and defended with three huge horns on top of their heads, and now scientists have found evidence of Triceratops fighting each other through fossil traces.

Triceratops is a plant-eating dinosaur with a total length of about 7 to 10 meters and a weight of 6 to 12 tons. It can be said to be a representative dinosaur of the late Cretaceous period. As the name suggests, Triceratops has three huge horns, which are located in the Above the eye sockets of the eyes and the bridge of the nose, many studies over the years have shown that Triceratops fought with the horns on the top of the head, and now Italian scientists have more direct evidence.

D’Annunzio University of Chieti-Pescara, Italy (D’Annunzio University of Chieti – Pescara) inspected the largest Triceratops fossil in history “Big John Big John)” and found a large hole on the right side of Big John’s neck, presumably injured by a similar species.

The Big John fossil is 66 million years old and is 8 meters high. The skull is 2.62 meters long and 2 meters wide. The two longest horns are about 1.1 meters long and over 30 cm wide, enough to withstand 16 tons of pressure. It was bought by an anonymous American collector on October 21 last year at Drouot, an auction center for art and antiques in Paris.

A team from the University of Chiedi-Pescara, Italy, found bone growth and signs of inflammation at the edge of the wound, showing that John was severely injured during his lifetime, and the wound was partially healed before his death, but why was John injured? The team speculated that it was another Triceratops, because no matter the size of the wound or the shape of the lesions, all the signs were completely consistent with the “horns” of the Triceratops, representing that Big John was fighting another Triceratops, and the opponent’s long horns stabbed the giant. John’s neck.

It’s just that the team doesn’t know whether the other Triceratops is “he” or “she”, and why they fight each other. After all, both male and female Triceratops may have horns. Unlike moose, only males can grow antlers. Male moose can grow antlers. To mate with a female, you also need to compete fiercely with other males. Scholar Ruggero D’Anastasio points out that other cases need to be studied to understand Triceratops’ behavior, but as far as he knows, other dinosaurs don’t fight each other.
