Why did Thylacosmilus go extinct?

Thylacosmilus became extinct after the land connection between North and South America was established during the middle of the Pliocene Epoch.

Where does Thylacosmilus live?

South America
Thylacosmilus was a saber-toothed mammal most closely related to marsupials, living in South America between seven and three million years ago.

When did Thylacosmilus go extinct?

Thylacosmilus died out during the Pliocene (3.6 to 2.58 Ma) whereas saber-toothed cats are not known from South America until the Middle Pleistocene (781,000 to 126,000 years ago). As a result, the last appearance of Thylacosmilus is separated from the first appearance of Smilodon by over one and a half million years.

What is Smilodon most closely related to?

Smilodon is a genus of the extinct machairodont subfamily of the felids. It is one of the most famous prehistoric mammals and the best known saber-toothed cat. Although commonly known as the saber-toothed tiger, it was not closely related to the tiger or other modern cats.

What did Thylacosmilus eat?

Why did the saber tooth have long teeth?

The cats’ oversized teeth were weapons, but their jaws weren’t built for strangulation or crunching through spines. Instead, these cats used their canines for slicing and ripping the softest parts for their prey — their throats and abdomens.

Was Smilodon a cat?

The best known saber-toothed cat, Smilodon, has sometimes been referred to as a saber-toothed tiger, although that is misleading because it is not closely related to tigers. Smilodon lived during the Pleistocene and early Holocene epochs before becoming extinct about 10,000 years ago.

Are Sabertooths real?

Sabertooths ranged widely throughout North and South America and are related to modern cats. However, no real descendents of the sabertooth cat are alive today. One hundred years of excavations at the La Brea tar pits have led to the recovery of over a million bones.
