description Avimimus portentosus Overview

Avimimus portentosus is a species of theropod dinosaur from the Late Cretaceous period, approximately 70 million years ago, discovered in Mongolia. Described by Russian paleontologist Sergei Kurzanov in 1981, this dinosaur was notable for its bird-like characteristics, including a toothless beak and evidence suggesting the presence of feathers. With a body length of about 1.5 meters, Avimimus had long legs indicating it was a fast runner, and its skeletal features provide important evidence for the dinosaur-bird connection.

help Avimimus portentosus FAQ

What was Avimimus portentosus?

Avimimus portentosus was a birdlike theropod dinosaur from the Late Cretaceous of Mongolia, roughly 70 million years ago. It had long hind limbs and other features that inspired its reputation as a bird mimic.

Who described Avimimus portentosus?

Russian paleontologist Sergei Kurzanov described the species in 1981. The original discovery came from Mongolia's Late Cretaceous fossil record.

Why is Avimimus called a bird mimic?

The name Avimimus refers to its birdlike anatomy, including its lightweight body and long legs. It was still a non-avian theropod dinosaur, so birdlike features do not make it a modern bird.

Was Avimimus portentosus a meat-eater?

Its exact diet is less certain than its broad theropod classification, but its beak-like jaws and birdlike anatomy have led to discussion of varied feeding habits. It should not automatically be treated as a large predator, because Avimimus was a lightly built animal from the Late Cretaceous.
