趣味知識

Ngexisaurus is an informal name for a dinosaur that has not been fully described by scientists yet.1

The type species is called Ngexisaurus dapukaensis, named by Zhao Xijin in 1983.1 2

Ngexisaurus lived during the Middle Jurassic, about 174 to 161 million years ago.2

Some scientists think Ngexisaurus might be a type of megalosaurid, a group of large meat-eating dinosaurs.1

Ngexisaurus is known only from fossils found in the Dapuka Group in Tibet, China.1 2
