Tamarro

名字的意思： “small and elusive fantastic creature from Catalan folklore, and 'unexpected' in Latin”1

吃：肉迅猛龍類白堊紀晚期

Tamarro was a small, fast-growing dinosaur that lived on an ancient island in what is now Spain. It was a troodontid, a group of bird-like, meat-eating dinosaurs. Scientists only know it from a single foot bone, but that bone has a unique hole not seen in any other troodontid.1

酷東西

趣味知識

Tamarro lived at the very end of the Cretaceous period, within 200,000 years of the asteroid that wiped out the dinosaurs.1

Its foot bone shows that Tamarro was a fast grower, reaching nearly adult size quickly, like many island animals.1

Tamarro is the first troodontid dinosaur ever found in Europe.1

The only known fossil of Tamarro is a single right second metatarsal, a bone from the foot.1

This foot bone has a special hole (a foramen) that is not found in any other troodontid, which helped scientists identify it as a new species.1

Tamarro lived on the Ibero-Armorican island, a large island that included parts of modern Spain, Portugal, and France.1

Scientists think Tamarro may have migrated from Asia to Europe, either by land bridges or by island hopping.1

關於 Tamarro 最常被問的問題

?What did Tamarro eat?

Tamarro was a meat-eating dinosaur, a troodontid, so it likely ate small animals. Scientists know this from its group, not from its single foot bone.3 1

?How big was Tamarro?

Tamarro was a small, mid-sized troodontid, but its exact size is unknown because only a foot bone has been found. It was a fast grower, reaching nearly adult size quickly.1 3

?When did Tamarro live?

Tamarro lived at the very end of the Cretaceous period, within 200,000 years of the asteroid that killed the dinosaurs. That was about 66 million years ago.1 3

?Where was Tamarro found?

Tamarro was found in Spain, on the Ibero-Armorican island that included parts of modern Spain, Portugal, and France. The fossil came from the Talarn Formation.3 1
