1

Bicentenaria was named to celebrate 200 years of Argentina's first independent government.1

2

Its fossils were found in a small area with bones from at least three different individuals.2

3

Scientists think Bicentenaria may have lived in groups because many skeletons were buried together.2

4

It lived alongside huge predators like Giganotosaurus, but was much smaller and more lightly built.2

5

Bicentenaria had special teeth with serrations only at the base of the crown.2

6

It is one of the earliest known coelurosaurs from the southern continents.2
