Alvarezsaurus
Alvarezsaurus was a tiny, fast-running dinosaur that lived in Argentina about 86 to 83 million years ago. It had a long tail and probably used its sharp claws to dig for insects. Scientists think it was one of the earliest members of a weird group of dinosaurs with strong, short arms.13

Alvarezsaurus was named after Don Gregorio Alvarez, an Argentine historian, not after a dinosaur scientist.1
Its third toe bone (metatarsal III) was the longest, and its fourth toe bone was unusually long too.1
Unlike many of its later relatives, Alvarezsaurus did not have its ankle bones (astragalus and calcaneum) fused together.1
The shoulder blade of Alvarezsaurus was curved and smaller than that of later alvarezsaurids like Mononykus.1
Its tail vertebrae had sharp undersides and triangular side projections, a feature shared with other alvarezsaurids.1
Alvarezsaurus is considered a basal (early) member of the alvarezsaurid family, which includes dinosaurs with strong, short arms and big claws.1

?How big was Alvarezsaurus?
Alvarezsaurus was small, about 1 to 1.4 metres (3.3 to 4.6 feet) long and weighed around 3 kilograms (6.6 pounds).1
?What did Alvarezsaurus eat?
It may have eaten insects. Its sharp claws and strong arms suggest it dug into termite or ant nests, though scientists are not completely sure.12
?Could Alvarezsaurus run fast?
Yes, its leg structure suggests it was a fast runner. It had long legs and a long tail for balance.12
?Did Alvarezsaurus have feathers?
No direct feather fossils are known for Alvarezsaurus, but a close relative, Shuvuuia, had downy, feather-like coverings, so it likely had feathers too.2
?When did Alvarezsaurus live?
It lived during the Late Cretaceous, about 86 to 83 million years ago, in what is now Argentina.1
?Was Alvarezsaurus a dinosaur?
Yes, Alvarezsaurus was a small theropod dinosaur, part of the alvarezsaurid family.1
