酷東西

趣味知識

Suskityrannus had the earliest known arctometatarsalian foot among its group, meaning its foot bones were pinched together for running fast.2 1

The fossils were discovered in 1998 by a geologist named Robert Denton and a teenage museum volunteer named Sterling Nesbitt.1

Suskityrannus lived during a time when sea levels were high and much of North America was underwater.2

Its name means 'coyote tyrant' in the Zuni language, because it was a small, clever predator like a coyote.1

The two known skeletons belong to young individuals that were still growing, but adults were still much smaller than later tyrannosaurs like T. rex.1

Suskityrannus filled a big gap in the fossil record, showing how small early tyrannosaurs evolved into giant ones.2

你們都在問

關於 Suskityrannus 最常被問的問題

?How big was Suskityrannus?

Suskityrannus was a small dinosaur. Its skull was only 25 to 32 centimetres (9.8 to 12.6 inches) long, and the known specimens were still growing, so adults were much smaller than later tyrannosaurs like T. rex.1

?What did Suskityrannus eat?

Suskityrannus was a predator, so it likely ate small animals like lizards, early mammals, and maybe baby dinosaurs. Its sharp teeth and fast legs helped it hunt.1 2

?When did Suskityrannus live?

Suskityrannus lived about 92 million years ago during the Turonian stage of the Late Cretaceous period.1 2

?Where was Suskityrannus found?

Suskityrannus fossils were found in the Moreno Hill Formation of the Zuni Basin in western New Mexico, USA.1

?Was Suskityrannus a dinosaur?

Yes, Suskityrannus was a dinosaur. It was a small tyrannosauroid theropod, which is a group of meat-eating dinosaurs that includes T. rex.1

?How fast could Suskityrannus run?

Suskityrannus had long legs and an arctometatarsalian foot, which means its foot bones were pinched together for speed. Scientists think it was a fast runner, but no exact speed is known.1 2
