Timimus

名字的意思： “Tim's mimic”1

吃：肉暴龍類白堊紀早期到白堊紀晚期

Timimus was a small, fast-running dinosaur that lived in ancient polar forests in Australia. It had long legs and sharp teeth, and it hunted smaller animals. Scientists used to think it was an ostrich mimic, but now they think it might be an early relative of T. rex!1 5

酷東西

趣味知識

Timimus lived about 106 million years ago, during the Early Cretaceous, in a polar region that had cold, dark winters.1

Its thighbone (femur) is 44 cm long, and scientists think the adult animal was about 2.5 to 4.3 metres long.1

The name Timimus honors both the discoverers' son Timothy Rich and paleontologist Tim Flannery.1

A study of its bone microstructure suggests Timimus may have hibernated during the cold, dark winter months.1

The holotype specimen is a single left thighbone (femur) from an adult, found in 1991 at Dinosaur Cove in Victoria, Australia.1 2

Scientists are not sure exactly what kind of dinosaur Timimus was. It was first thought to be an ornithomimosaur (ostrich mimic), but now many think it might be a tyrannosauroid, an early relative of Tyrannosaurus rex.1 5

關於 Timimus 最常被問的問題

?How big was Timimus?

Timimus was about 2.5 to 4.3 metres long and weighed around 200 kg. It stood about 1.2 metres tall at the hips.1 4

?Did Timimus have feathers?

Scientists think Timimus may have had a partial covering of feathers or proto-feathers, especially since it lived in a cold polar climate. However, no direct fossil evidence of feathers has been found.4

?Could Timimus hibernate?

Yes, a study of its bone microstructure suggests Timimus may have hibernated during the cold, dark winter months. Its bones show a stop-start growth pattern, unlike some other dinosaurs from the same area.1 4

迷思破解王

迷思： Timimus was an ostrich-like dinosaur that ran very fast and ate plants.

真相： Timimus was originally thought to be an ornithomimosaur (ostrich mimic), but newer studies suggest it was a carnivorous theropod, possibly a tyrannosauroid. It was a meat-eater, not a plant-eater.1

發現: Timimus was named in 1993/1994 by Dr. Thomas Rich and his wife Patricia Vickers-Rich. The fossils were found in 1991 at Dinosaur Cove East in Victoria, Australia. The species name hermani honors volunteer John Herman.1 2
仍有爭議: Scientists still debate whether Timimus is a tyrannosauroid, a dromaeosaurid, or a different kind of coelurosaur. Some even consider it a nomen dubium (doubtful name) because the fossils are so incomplete.1
