趣味知識

Dineobellator had special features on its arm bones that gave it a stronger grip than other raptors, helping it hold onto struggling prey.2 1

Its tail bones allowed it to move its tail more flexibly near the base, which may have helped it turn quickly while chasing prey.2 1

Dineobellator lived alongside many other dinosaurs, including T. rex, and scientists think it filled a different hunting role than the giant predator.2 1

It is the first well-known raptor from the very end of the Cretaceous in the southern United States.2 1

Dineobellator belongs to a group of raptors called Velociraptorinae, which includes the famous Velociraptor.2 3

Its fossils were found in rocks that are about 66.5 million years old, very close to the time when all non-bird dinosaurs went extinct.2 1

關於 Dineobellator 最常被問的問題

?How big was Dineobellator?

About 1.1 metres (3.5 feet) tall at the hip and 1.8 to 2.1 metres (6 to 7 feet) long, similar in size to a large raptor like Deinonychus.4 5

?Did Dineobellator have feathers?

Yes. Quill knobs on its arm bones show that it had feathers, just like other dromaeosaurids such as Velociraptor.4 5

?What did Dineobellator eat?

It was a predator that likely ate small animals like birds and lizards, and may have used its strong grip to catch larger prey. It lived alongside fish, turtles and mammals that could have been its prey.4 5

?When did Dineobellator live?

It lived about 66.5 million years ago, near the very end of the Cretaceous Period, just before all non-bird dinosaurs went extinct.1 5

?Was Dineobellator bigger than Velociraptor?

It was similar in size to Velociraptor, but some studies suggest it was about as big as Deinonychus, which is larger than Velociraptor.5

?Did Dineobellator live with T. rex?

Yes. Dineobellator lived in the same time and place as Tyrannosaurus rex, but it filled a different hunting role as a smaller, agile predator.1 5
