Walkeria

Dzina limatanthauza: “for Alick Walker”1
Madainoso oyambaKumapeto kwa Triasiki

Walkeria was an early reptile that lived in India during the Late Triassic, about 228 million years ago. It was a small, two-legged animal that scientists once thought was a dinosaur, but now they are not so sure.1

1

Walkeria was first named in 1987 by paleontologist Sankar Chatterjee, but the name was already used for a tiny sea animal, so it was changed to Alwalkeria in 1994.1

2

The fossils of Walkeria are a mix of bones from different animals, like a puzzle. The skull might belong to a crocodile-like reptile, while the leg bones could be from a dinosaur.1

3

Walkeria lived in a place that was once an ancient lake or river in what is now India.1

4

Some scientists think the thigh bone of Walkeria looks like that of a lagerpetid, a group of small, agile reptiles that were close relatives of pterosaurs.1

5

Because its fossils are so mixed up, scientists are not sure if Walkeria was a dinosaur, a crocodile relative, or something else entirely.1

Sankar Chatterjee named Walkeria in 1987 based on a partial skull, vertebrae, and leg bones found in the Maleri Formation of India. The name was later changed to Alwalkeria because 'Walkeria' was already taken.1
Akukambiranabe
Scientists still debate whether Walkeria was a dinosaur, a crocodile-like reptile, or a lagerpetid, because its fossils are a mix of different animals.1
