Are Smilodon and Thylacosmilus related?

Though Thylacosmilus looks similar to the “saber-toothed cats”, it was not a felid, like the well-known North American Smilodon, but a sparassodont, a group closely related to marsupials, and only superficially resembled other saber-toothed mammals due to convergent evolution.

What is Smilodon and Thylacosmilus?

No bigger than a modern jaguar, Thylacosmilus was small compared to Smilodon, but they both had very powerful necks, shoulders, and forelimbs. While a cat might sound fiercer than a marsupial any day, Thylacosmilus’ extra-long and pointy fangs were actually longer than the cat’s teeth, compared to body size.

Why did the Thylacosmilus go extinct?

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

How did Thylacosmilus eat?

Dr. Janis reported in the journal PeerJ last month that the findings reveal an animal that was definitely not a marsupial version of Smilodon. As for what it was actually doing, she proposes that Thylacosmilus was a scavenger that employed its huge canines to rip carcasses apart and then gobbled up organs.

Are saber-tooth tigers still alive today?

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.

Is a saber tooth tiger real?

The “saber-toothed tiger,” Smilodon, is the California State Fossil and the second most common fossil mammal found in the La Brea tar pits. The name “saber-toothed tiger” is misleading as these animals are not closely related to tigers. Juvenile to adult-sized fossils are represented in the large Berkeley collections.

How did saber-tooth tigers bite?

Even though their canines were massive and intimidating, their jaws weren’t strong enough to bite through bones. So, the cats had to use their canines like knives as opposed to crushing the spines of their prey. Saber-tooth cats had baby teeth, just like humans and other mammals have.

How strong is a saber-tooth tiger bite?

Speedy bite The models show that a 250-kilogram lion can generate a force of 3000 Newtons with its bite, while a 230-kg sabre-tooth cat can produce just 1000 Newtons. The models also show that a lion’s teeth and skull are built to withstand the forces encountered with dealing with large, struggling prey.

Do saber tooth tigers still exist?

Scientists have learned that the sabertooth cat first appeared in the archaeological record two million years ago. 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.
