Brevicaudosaurus

Naam beteken: “short-tailed lizard”1

Het geëet: VleisSeereptieleMiddel-Trias tot Laat TriasTegnies nie 'n dinosourus nie

Brevicaudosaurus was a small marine reptile that lived in the sea during the Triassic Period. It had a very short, flat tail and a broad, flat body, so it probably swam slowly and hunted near the seafloor.1

Prettige feit: hierdie seereptiel het geswem terwyl dinosourusse op land geloop het. Almal noem hulle dino's, maar hulle was 'n ander tak van die reptiele.

Prettige feite

Brevicaudosaurus means 'short-tailed lizard' because its tail was unusually short and flattened compared to other marine reptiles like it.1

A baby Brevicaudosaurus was only about one-third the length of an adult, and its teeth were small and smooth instead of fang-like.1 2

Adult Brevicaudosaurus had fang-shaped teeth in the front of the upper jaw, which helped them grab big prey.1 2

Scientists think Brevicaudosaurus lived on the seafloor and ate animals that lived there, because its flat body and short tail made it a slow swimmer.1

The first Brevicaudosaurus fossil was described in 2020, and a baby skeleton was found later in 2025.1 2

Brevicaudosaurus lived about 240 million years ago, during the Middle Triassic, in the ocean that covered what is now southern China.1 3

Wetenskaplike naam: Brevicaudosaurus
Benoem deur: Shang et al. 20203
Groep: Seereptiele
Familie / klade: Nothosauridae3
Klassifikasie: Sauropterygia3
Ouderdom van die rotse: 241 tot 227 miljoen jaar (Ladinian / Carnian)3

Ontdekking: Brevicaudosaurus was named in 2020 by scientists Shang, Wu, and Li based on a fossil found in Fuyuan, Yunnan Province, China.1 3
Steeds omstrede: Scientists are not sure exactly where Brevicaudosaurus fits on the family tree of marine reptiles. Some studies place it close to nothosaurs, while others put it outside that group.1
