Tanycolagreus

名字的意思： “long-limbed hunter”1

吃：肉肉食恐龍侏羅紀晚期到白堊紀早期

Tanycolagreus was a fast, meat-eating dinosaur that lived in North America during the Late Jurassic. It had long legs and arms, which helped it chase down small prey like lizards and early mammals. Scientists think it was about as long as a small car!1

酷東西

趣味知識

Tanycolagreus had longer arms and legs than its close relative Coelurus, which is why its name means 'long-limbed hunter'.1

The first fossil of Tanycolagreus was found in 1995 at the Bone Cabin Quarry West in Wyoming, but it was not named until 2005.1

The holotype skeleton includes parts of the skull, backbone, arms, legs, and tail, but the skull is less complete than the rest of the body.1

A premaxilla (front upper jaw bone) from the Cleveland-Lloyd Quarry in Utah belonged to a larger Tanycolagreus, possibly up to 4 meters long.1

Tanycolagreus lived in the Morrison Formation, the same rock layer that produced famous dinosaurs like Stegosaurus and Apatosaurus.1

Scientists are not sure if Tanycolagreus was an early tyrannosauroid or a more primitive coelurosaur, because different studies place it in different groups.1

關於 Tanycolagreus 最常被問的問題

?How big was Tanycolagreus?

About 3.3 meters (11 feet) long, roughly the size of a small car. One larger fossil suggests it could reach 4 meters (13 feet) long.1

?What did Tanycolagreus eat?

It was a meat-eater. It likely hunted small prey like lizards and early mammals, and may have preyed on small dinosaurs like Nanosaurus.1 2

?When did Tanycolagreus live?

It lived during the Late Jurassic period, about 150 million years ago, in what is now North America.1 2

?Was Tanycolagreus a dinosaur?

Yes, it was a theropod dinosaur, a group of meat-eating dinosaurs that walked on two legs.2

?Where was Tanycolagreus found?

Fossils were found in Wyoming, Utah, and Colorado, in the Morrison Formation. The first skeleton was found in 1995 at Bone Cabin Quarry West in Wyoming.1

?Why is it called Tanycolagreus?

Its name means 'long-limbed hunter' because its arms and legs were longer than those of its close relative Coelurus.1
