Anabisetia is believed to be an Ornithipoda from the Late Cretaceous period that belongs to Patagonia. The ornithopods were running and grazing herbivorous dinosaurs which formed one of the largest group bipedal dinosaurs in the Cretaceous period. The Anabisetia cannot be placed in any clade precisely as of yet since unclear fragments of its skull have been discovered. The Anabisetia is a dinosaur from the late Cretaceous period. The Cretaceous period is the longest and the final period of all the three periods of the Mesozoic era, as well as the entire Phanerozoic era.

They existed during the later stages of this period and roamed on earth around 95 million years ago and perished 92 million years ago. This gave this Ornithopoda a total span of three million years on earth. The genus along with its classification formed a major part of the earth's fauna in between the Turonian and the Cenomanian stage of the Cretaceous period. This geological period ended with the mass extinction of many dinosaurs and large reptiles and Anabisetia was one of them. To know more about these dinosaurs, keep on reading these facts.

Anabisetia Interesting Facts

How do you pronounce 'Anabisetia '?

The Anabisetia is a comparatively modern dinosaur genus that was found during the third and the final phase of the Mesozoic era in the late Cretaceous period. The English name of Anabisetia s pronounced 'as ah-na-bee-set-ee-a'.

What type of dinosaur was an Anabisetia?

The Anabisetia is a small bipedal herbivore dinosaur that is assumed to be the closest relative of the Patagonian ornithopod called Gasparinisaura. The related dinosaur Gasparinisaura and Anabisetia were considered to be some of the earliest ancestors of the Iguanodontia species. An iguanodontian is a group of many generation ancestors of small bipedal dinosaurs that belonged to the Middle Jurassic to the Late Cretaceous era. However recent research has shown that Gasparinisaura lied outside the group of the Iguanodontia of South America. Their fossil rather corresponded to the ornithopods of North America.

In which geological period did the Anabisetia roam the earth?

The Anabisetia is an Ornithopoda dinosaur that belonged to the Late Cretaceous period and lived in ancient Patagonia including some adjoining places of present Argentina and Chile. This geological period lasted for over 80 million years. This long geological period started around 145 million years ago, lasted for more than 80 million years, and finally ended around 66 million years ago. The genus Anabisetia including Gasparinisaura emerged on earth during the later years of the Cretaceous period. The Anabisetia roamed on the earth's surface around 95 million years ago to 92 million years ago. The classification of the Cretaceous period consists of several stages. These dinosaurs of Patagonia including Argentina came into existence during the late Cenomanian stage of the Cretaceous periodical classification and lasted till the Turonian stage.

When did the Anabisetia become extinct?

The Anabisetia dinosaurs is a Mesozoic genus of dinosaurs that lived in Patagonia during the later Cretaceous period. They became active around 95 million years ago and became extinct after three million years. By the Turonian stage around 92 million years ago, all the remaining Anabisetia became extinct.

Where did an Anabisetia live?

The Anabisetia fossil specimens have been collected from the adjoining areas of present-day Argentina. These primitive animals were endemic to Patagonia in South America.

What was an Anabisetia's habitat?

The Anabisetia was a highly territorial family of dinosaurs, they predominantly lived in terrestrial habitats. They inhabited lands like grasslands, forests, wetlands, and shores.

Who did an Anabisetia live with?

The Anabisetia was a genus of small bipedal dinosaurs that live in primitive Patagonia of South America including present-day Argentina and Chile. They were considered to be the close relatives of another species of Ornithopod called the Gasparinisaura. Based on the indeterminate skull structures of the species of two genera, it cannot be concluded whether belonged to the same group or in separate groups. When the fossils of these dinosaurs were discovered, four specimens were discovered from Argentina in rock sediments. However, they were not found in bone beds so including all the four specimens to be a part of an Anabisetian herd will be vague. However, the curved spines of the ornithopods resemble the spine of present-day group feeders. So it can be considered that present-day herding herbivores emerged from such types of dinosaurs.

How long did an Anabisetia live?

The dinosaurs of the Anabisetia genus live for a short span of three million years. These dinosaurs were a small group of herbivore dinosaurs that was washed out from Patagonia in South America during the abrupt ending of the Cretaceous age. The Cretaceous period is the last and final period of the Mesozoic era lasted from 66-145 million years ago. This era abruptly came to an end with the Cretaceous–Paleogene extinction event.

How did they reproduce?

There is no information regarding the litter size or the reproductive behavior of Anabisetia. The only thing known about this genus is that they reproduced by laying eggs.

Anabisetia Fun Facts

What did an Anabisetia look like?

An Anabisetia is a small bipedal herbivore that lived in the cretaceous period along with Gasparinisaura. The dinosaur had a connector at the back of the head that pointed downwards. The lower rim of the shoulder blade largely extended outside that was the largest that was found in any Ornithopoda. The front blade of the ilium in the pelvis accounted for most of the ilium. The fibula bone of the ankle seemed to touch the astragalus.

The scientific name of Anabisetia is A. saldiviae.

How many bones did an Anabisetia have?

The total number of bones that an Anabisetia had is unknown but a partial skull fragment including jawbones, fragmentary braincase, and dentary bones was discovered. A complete forelimb extending from the shoulder to claws and a complete hindlimb up to the feet was also discovered. Apart from that, a spinal column containing all vertebrate segments was also found.

How did they communicate?

Dinosaurs generally communicate by vocalizations. They also have developed visual senses, which help in communication.

How big was an Anabisetia?

The average length of an Anabisetia is believed to be 6 ft 7 in (2 m). They are twice bigger than Ohmdenosaurus.

How fast could an Anabisetia move?

The speed of the movement pattern of Anabisetia could not be tracked by discovered fossils.

How much did an Anabisetia weigh?

The Anabisetia was a small dinosaur that weighed up to 44 lb (20 kg).

What were the male and female names of the species?

The male and the female species do not have any particular name, both of them are referred to as Anabisetia.

What would you call a baby Anabisetia?

The baby dinosaur is referred to as a nestling or hatchling.

What did they eat?

The Anabisetia were herbivorous grazers in nature, their diet consisted of tree leaves and grass. Several carnivorous predators including abelisaurids and carcharodontosaurids preyed on them.

How aggressive were they?

They are herbivorous and small dinosaurs which makes them less aggressive than the flesh-eating ones.

Did you know...

The type species of the Anabistia, A. saldiviai was named after the local farmer Roberto Saldivia Blanco of Argentina who discovered the fossil of this genus for the first time.

What does Anabisetia mean?

The genus name Anabisetia of one of the groups of prehistoric dinosaurs does not have any meaning related to it. Their name is in honor of the great archaeologist Ana Maria Biset that lived in the town where the fossil of this dinosaur was first discovered in Argentina.

Was anabisetia bipedal?

Yes, the Anabisetia was a small and bipedal dinosaur. They were ornithischians therefore their feet probably consisted of three digits. However, some ornithischians also consisted of four toes in their feet.
