Fun Eoabelisaurus Facts For Kids

Since the dawn of time, people have always feared carnivores and other dangerous animals. New research-based data reveals that the Eoabelisaurus was one of the most well-known and feared dinosaurs around when talking about dinosaurs.

Large in height, weight, and strength, this is one dinosaur with a range big enough to be dangerous. They primarily fed on smaller animals and plant-eating dinosaurs.

They would probably also feed on smaller carnivorous dinosaurs. Much like other reptiles, it has been assumed that they too had scaly skin and a dull coloring of green, brown, and red.

You can learn everything there is to know about the Eoabelisaurus diet, and so much more! Read on to know more about research on the classification of the Eoabelisaurus and other interesting facts, or check out other new and interesting dinosaurs like the Zuniceratops and Orodromeus.

Eoabelisaurus Interesting Facts

How do you pronounce Eoabelisaurus?

The word Eoabelisaurus is pronounced as 'E-oh-ah-bel-e-sore-us'. It was named by Diego Pol‭, ‬Oliver‭, and ‬Rauhutin 2012. ‭

What type of dinosaur was an Eoabelisaurus?

Eoabelisaurus mefi is an Abelisaurid theropod dinosaur.

In which geological period did the Eoabelisaurus roam the earth?

The Eoabelisaurus, an Abelisaurid dinosaur, may have roamed the earth in the late Cretaceous period. The skull that was discovered belonged to this era.

When did the Eoabelisaurus become extinct?

Their ancestors lived during the middle Jurassic period, approximately 163 million years ago. The group and the rest of the non-avian dinosaurs became extinct 66 million years ago during the Cretaceous-Paleogene extinction event. This Abelisaurid dinosaur died around the same time.

Where did an Eoabelisaurus live?

Eoabelisaurus mefi was a theropod dinosaur genus in the Abelisauridae family, and therefore an Abelisaurid. Eoabelisaurus was an Abelisaurid species that lived in South America during the late Cretaceous period and had tiny forelimbs and long legs. This is due to the discovery of the Eoabelisaurus skull here.

What was an Eoabelisaurus's habitat?

In terms of diet, Eoabelisaurus was a carnivore and an Abelisaurid that ate meat. At the beginning of the Jurassic period, the Eoabelisaurus mefi lived in South America. Its remains, or fossil, were discovered in Argentina and belonged to a subadult or mature adult of this theropod.

Who did an Eoabelisaurus live with?

Their behavior was solitary and the Eoabelisaurus mefi frequently fought with fellow Eoabelisauruses.

How long ago did the Eoabelisaurus live?

Eoabelisaurus lived from 83.5-70.6 million years ago.

How did they reproduce?

Since the only thing discovered about this early Jurassic era creature is a partial skull, scientists have not named a single way of reproduction and keep the room open for diversification.

Eoabelisaurus Fun Facts

What did an Eoabelisaurus look like?

It was a bipedal carnivore that grew to a length of 19.7–21.3 ft (6–6.5 m), and a full abelisaur size analysis undertaken in 2016 yielded a size estimate of 19 ft (5.7 m).

The holotype specimen, MPEF PV 3990, was discovered in a stratum of the Caadón Asfalto Formation, a lacustrine deposit from the Aalenian-Bajocian period, approximately 170 million years ago.

It consists of a nearly complete skeleton of a subadult or mature individual, including the skull.

Both humeri from known material are in poor condition, but they exhibit primitive characteristics. The articular head is moderately rounded but not in the globular shape that Abelisaurids and Noasaurids are known for.

Manual unguals are decreased, and non-terminal manual phalanges are as long as they are wide, with no constriction between articular ends. It was a primitive Abelisaurid, as evidenced by its reduced limb proportions.

Due to multiple holes in the spine (holotype), the cervical vertebrae are small and have two pneumatic foramina on each side of the centra. Over the preserved stretch of the tail, the size of the vertebral centra remains consistent, while the middle and rear caudals are significantly shorter.

How many bones did an Eoabelisaurus have?

The skull of the Eoabelisaurus skeleton was discovered slightly apart from the vertebral column. At the time of discovery, the skull and front presacral were also revealed and had been substantially obliterated by erosion.

Only a little portion of the right maxilla has been retrieved from the snout's known material. The back of the skull is known to be high, with an oval orbit.

The roof of the skull is not noticeably enlarged, and there is no cranial ornamentation. This is all known about their bone structure, and no solid number has been determined for this creature.

How did they communicate?

There are no records of the ways in which they communicated.

How big was an Eoabelisaurus?

This theropod species of the middle Jurassic Abelisaurid from Patagonia was about 21 ft (6.4 m). The average length of a giraffe is approximately 13.1-13.7 ft (4-4.17 m). Therefore, this species was much larger than a giraffe!

How fast could an Eoabelisaurus move?

Since research based on their diet has named this creature a carnivore, they needed to be fast to catch their prey. The exact speed at which they moved is unknown.

How much did an Eoabelisaurus weigh?

The weight of this Abelisauridae family species and fossil unearthed in Patagonia, Argentina was around 1.54-3 short tons (1.3–2.7 metric tons), which is significant due to its relative completeness.

What were the male and female names of the species?

There are no sex-specific names for this dinosaur.

What would you call a baby Eoabelisaurus?

The baby of the species (E. mefi), discovered in the Cañadón Asfalto Formation of Argentina, South America, lived around 170 million years ago, doesn't have any specific name.

What did they eat?

Eoabelisaurus most probably hunted large sauropod dinosaurs in packs, like Amargasaurus. However, it may have also hunted small plant-eating dinosaurs like Gasparinisaura, a small ornithopod.

How aggressive were they?

The early classification and diversification of this Abelisaurid species would classify them as moderately to highly aggressive. This is because since the dawn of the Jurassic era, and even in the early days of the Cretaceous era, they were hunters, and by default, were aggressive.

Did you know?

The discovery, published online on May 23 in the journal Proceedings of the Royal Society B, shows that the abelisaurids, whose genesis has remained a mystery, evolved 40 million years earlier than previously assumed.

Abelisaurids were tyrannosaurid-like creatures that stalked the land on two legs.

The majority of Eoabelisaurus are known from the Late Cretaceous period.

How did the Eoabelisaurus get its name?

Their generic name combines the Greek word (eos), which means 'dawn', with the name Abelisaurus.

Were they social/pack hunters?

It's conceivable that these group hunters dinosaurs (Eoabelisaurus mefi) developed a hunting technique that needed them to use their teeth. According to fossil evidence, these dinosaurs had a tremendous bite and strong, pointed teeth, which would have made them excellent hunters of other large dinosaurs that occupied their habitat.
