Fun Orkoraptor Facts For Kids
Gallery
A genus of medium-sized theropod dinosaur, the Orkoraptor (Orkoraptor burkei) belonged to the Late Cretaceous period that lasted from 100.5-66 million years ago. By looking at the anatomical features, authors like Novas, Ezcurra, and Lecuona stated that it was a maniraptoran coelurosaur. However, several studies placed the Orkoraptor burkei species in the Megaraptora clade.
The term 'orkoraptor; was derived from an Aoniken word 'Orr-korr' which was generally used to refer to the La Leona River. The local meaning of Orkoraptor is 'toothed river thief'. The species Orkoraptor burkei was named in honor of Coleman Burke, a paleontologist who played a significant role in the expedition that collected the original fossil.
The average weight and length of this Cretaceous species is thought to be around 1,102-3,087 lb (500-1,400 kg) and 20-27.5 ft (6-8.4 m).
In 2001, a fossil was excavated that consisted of broken parts of the skull, a right postorbital, a right quadratojugal, eight isolated teeth, a right coronoid, two proximal caudal vertebrae, eight broken ribs, three incomplete chevrons, and a partial tibia.
Initially, due to the upturned anterior process of the postorbital, as well as specialized teeth, the species was believed to be a coelurosaur.
These were carnivorous dinosaurs that used to prey on lizards, fishes, insects, and small mammals. The first fossil of the species was collected from the Pari Aike Formation in Argentina.
The Pari Aike Formation is now considered to be either the middle section of the Mata Amarilla Formation or an alternative name for the Cerro Fortaleza Formation. It can be said that these large Cretaceous dinosaurs must have inhabited coastal areas, tundra regions, forests, and plains.

The specimens recovered are from the late Cretaceous period that generally lasted from about 100.5-66 million years ago. It is also known as the third and final Mesozoic era.
When did the Orkoraptor become extinct?
The exact time period of extinction is not known but it is believed that these theropods went extinct around 76-70 million years ago. The middle section of the Mata Amarilla Formation contained a layer that has been dated to around 96 million years ago.
Before that period, the species was found in several parts of South America. The major cause of extinction is not known, but in general, factors such as climate change, asteroid impact, and several other natural disasters are thought to be responsible.
Where did an Orkoraptor live?
These dinosaurs were quite widespread in South America. One specimen was recovered from the Pari Aeki Formation in south Patagonia, Argentina. The name was derived from the native name of La Leona River of Argentina, Orr-korr, where the original fossil site is located.
The Pari Aike Formation is now considered either the middle section of the Mata Amarilla Formation or an alternative name for the Cerro Fortaleza Formation.
What was an Orkoraptor's habitat?
It is believed that this large theropod species inhabited coastal areas, tundra regions, forests, plains.
Who did an Orkoraptor live with?
By looking at the trackways of these theropods, it can be said that these dinosaurs were solitary and used to hunt alone. However, male and female dinosaurs must have been found in a pair during the breeding season.
How long did an Orkoraptor live?
The lifespan of the Theropoda clade is not known.
How did they reproduce?
