Ivantosaurus

Ivantosaurus was a beast of the past
A therapsid with canines so vast
It lived in Russia long ago
When the Permian was in full flow

It hunted prey with a deadly bite
Its teeth could pierce through skin so tight
It was named after a paleontologist
Who studied fossils with great interest

Ivantosaurus was a giant among its kind
The largest carnivore you could find
It was a cousin of the mammals today
But it went extinct in a mass decay

Ivantosaurus is an extinct genus of therapsid that lived in Russia during the Wordian stage of the Permian period, named in honor of paleontologist Ivan Antonovich Efremov.
It was carnivorous and may have grown to a length of 6 m (20 ft).

Ivantosaurus is an extinct genus of therapsid, a group of mammal-like reptiles that lived in the Permian period.

It was named after the paleontologist Ivan Antonovich Efremov, who studied fossils from Russia.

Ivantosaurus was a large carnivore, with a skull length of about 55 cm and a body length of about 6 m.

It had two long, saber-like canine teeth in its upper jaw, which it used to pierce the thick skin of its prey, such as the herbivorous estemmenosuchids.

Ivantosaurus was one of the last therapsids, living in the Wordian stage, about 267 million years ago.

It was closely related to Eotitanosuchus, another saber-toothed therapsid from the same region and time.

Ivantosaurus is known from very fragmentary fossils, so its exact appearance is uncertain.

It may have looked similar to a gorgonopsid, a more advanced therapsid with a long snout and a sleek body.

Ivantosaurus probably had a coat of fur or hair, as some therapsids did, and may have been warm-blooded.

Ivantosaurus was a unique and impressive animal, one of the earliest examples of saber-toothed predators in the history of life.
