名字的意思： “small rhea, after the Tupi-Guarani words for 'running bird' and 'small'”1 2

吃：肉最早的恐龍三疊紀晚期

Nhandumirim was a tiny, fast-running dinosaur that lived in Brazil over 230 million years ago. It was one of the earliest dinosaurs ever, and scientists think it may be a very early relative of the meat-eating theropods like T. rex!2 4

酷東西

趣味知識

Nhandumirim means 'small rhea' in the Tupi-Guarani language, because it was a speedy little dinosaur like a rhea bird.2 1

Its fossils were found in a small area, only about 50 centimeters wide, and were semi-articulated, meaning many bones were still in their original positions.2

The tail bones of Nhandumirim have a sharp keel along the bottom, a feature that helps scientists tell it apart from other early dinosaurs.2

Nhandumirim lived in a floodplain environment, alongside other ancient animals like the rhynchosaur Hyperodapedon and the early dinosaur Saturnalia.1

This dinosaur is about 233 million years old, making it one of the oldest known dinosaurs from the Triassic Period.2 4

Scientists think Nhandumirim could run fast on its long, slender legs, just like the bird it was named after.2

?What did Nhandumirim eat?

Scientists are not sure, but because it is an early sauropodomorph, it was probably a plant-eater. Some studies suggest it might have been a meat-eater like early theropods.3

?When did Nhandumirim live?

It lived about 233 million years ago during the Late Triassic Period, in what is now Brazil.3

學名: Nhandumirim
命名者: Marsola et al. 20194
類群: 最早的恐龍
科 / 演化支: Saurischia4
岩石的年代: 227 到 206 百萬年 (Norian)4
岩層: Caturrita4
國家: 巴西4
化石紀錄: The Paleobiology Database 收錄 1 筆4
發現: Nhandumirim was named in 2019 by a team of scientists including J. C. A. Marsola, based on a partial skeleton found at the Waldsanga site in Brazil. The fossils were first collected from the red mudstones of the Santa Maria Formation.4 2
仍有爭議: Scientists are not sure if Nhandumirim is a true theropod or just a very close relative, because it has some features that are similar to both theropods and other early dinosaurs.2
