Adasauruses, or ada lizards (in Mongolian mythology), were sickle-shaped terrestrial lizards who existed in Asia. They lived in the Nemegt Formation in Mongolia and ate other smaller or similar-sized herbivores. They were small dinosaurs who were the size of a big chicken. They most probably hunted in groups. They were bird-like dinosaurs who had feathers on their body. They had a very long tail that seemed elegant. They had a small skull and small hands. However, the hands had a small feather-like structure on them. They were in the family Dromaeosauridae and in dinosaur clade Saurischia, Theropoda and Dromaeosaurinae. They were fast runners and had hollow bones for helping in attaining that speed.

This is just the introduction part. Ahead in the article, there are multiple interesting and funny Adasaurus facts waiting for you to make you amazed.

What type of dinosaur was an Adasaurus?

They belonged to the dinosaur clade Theropoda and Saurischia. They were in the family Dromaeosauridae and subfamily Velociraptorinae. They also belonged to the dinosaur clade Eudromaeosauria. Their genus name is Adasaurus and their scientific name is Adasaurus mongoliensis. Mongoliensis because their fossil remains were found in Mongolia.

In which geological period did the Adasaurus roam the earth?

The Mongolian dinosaur, Adasaurus mongoliensis roamed the Earth during the Late Cretaceous period of the Mesozoic era around 70 million years ago. Their partial specimens were excavated from Mongolia that means they lived in the continent of Asia.

When did the Adasaurus become extinct?

The Mongolian dinosaur, Adasaurus, was present on Earth during the Late Cretaceous period. It is assumed that the extinction of Adasaurus happened during the end of the late cretaceous period. They roamed the Earth around 70 million years ago.

Where did an Adasaurus live?

The Mongolian lizard species, Adasaurus, were terrestrial hunters. They were small in size if compared to a fully grown human, and were most probably pack hunters. They would have lived in forests and other parts of Mongolia.

So it can be assumed that these Mongolian dinosaurs also had an average lifespan of around 15 years. They were present on Earth from 66-70 million years ago.

How did they reproduce?

These dinosaurs from the subfamily Velociraptorinae, Dromaeosaurinae were reptiles obviously. And reptiles lay eggs in order to give birth.

Adasaurus Fun Facts

What did an Adasaurus look like?

Both the holotype and paratype specimens of Adasaurus is incomplete

Adasaurus were sickle-shaped lizard species that were closely related to birds. They were carnivorous animals from the subfamily Velociraptorinae and Dromaeosaurinae. For an overview of their features, Adasaurus were small meat-eating reptiles who had a bird-like appearance. They had feathers on their bodies. Their forelimbs seemed like small wings equipped with sharp claws. They had a small skull with a beak and a long tail. Their hindlimbs were strong. According to the fossil (specimen) studies, it was seen that they were closely related to velociraptors. Now to describe their features, the Adasaurus dinosaur fossil was devoid of a complete skull. The skull was partial and the interior region was absent. Both the holotype and paratype specimens were incomplete. They had strong hindlimbs that could carry their whole body, they were bipedal and could run at a good speed. They had a really long tail that had long feathers on it. Actually, these tails supported their sickle-shaped bodies and helped in balancing them. They had sharp claws for catching and suppressing their prey. On their hand, there were small feathers attached that seemed like small wings. It was just for showing as they couldn't fly. Some portions that were missing (incomplete) from their skeleton or fossil are the sternal plate, eight cervical vertebrae, 11 partial dorsal vertebrae, the sacrum, seven caudal vertebrae, partial hindlimbs, and some other parts also. The length of the skeleton was around 7.9 ft (2.4 m) and from the specimen, their body weight was assumed around 80 lbs (36.3 kg). They were not that tall.
