Question 1

How do you say Dinofelis?

Accepted Answer

Dinofelis is pronounced DY-no-FEE-lis. Break it into three parts: DY (rhymes with 'sky'), no (like the word 'no'), and FEE-lis (rhymes with 'feel this'). The stress lands on the third syllable, FEE. A good memory trick is to say 'Die, no, feel this,' which also happens to sound like something Dinofelis's prey might have thought.

Question 2

What does Dinofelis mean?

Accepted Answer

Dinofelis means 'terrible cat.' The first part of the name comes from the Greek word 'deinos,' which means terrible or fearsome and is the same root found in 'dinosaur.' The second part, 'felis,' is the Latin word for cat, the same root used in Felidae, the scientific name for the entire cat family. Taken together, the name is a pretty accurate description of a predator that may have hunted our own early human ancestors.

Question 3

Did Dinofelis hunt humans?

Accepted Answer

There is strong fossil evidence that Dinofelis preyed on early human relatives. Paleontologist C. K. Brain found hominin skulls at South African cave sites like Swartkrans with puncture marks that match the spacing of Dinofelis canine teeth almost exactly. These early hominins, including Paranthropus and possibly early Homo species, lived in the same areas as Dinofelis between roughly 1.5 and 2 million years ago. While no one can say for certain that Dinofelis was the sole predator responsible, the evidence strongly suggests it was hunting our ancestors on a regular basis.

Question 4

Was Dinofelis a real saber-tooth cat?

Accepted Answer

Dinofelis was a member of the saber-toothed cat subfamily Machairodontinae, so technically yes, it was a saber-tooth. However, its canines were much shorter than those of the famous Smilodon, whose fangs reached around 11 inches. Dinofelis had elongated, flattened canines that were clearly more weapon-like than any modern cat's teeth, but they fell in the middle range for machairodontines. Some scientists call it a 'false saber-tooth' because it did not develop the extreme fang length seen in other members of its group.

Question 5

How big was Dinofelis?

Accepted Answer

Dinofelis was roughly the size of a large modern leopard, reaching about 4.5 to 6 feet in body length and weighing somewhere between 110 and 220 pounds depending on the species. It was more robustly built than a leopard, with a broader skull, heavier forelimbs, and a more compact, powerful body. Think of it as a leopard that had been bulked up considerably in the shoulders and arms, built more for wrestling prey to the ground than for speed.

Question 6

Where did Dinofelis live?

Accepted Answer

Dinofelis was one of the most geographically widespread prehistoric predators known. Fossils have been found in Africa including South Africa, Kenya, Tanzania, Ethiopia, and Chad, as well as in Europe in countries like Spain, and across Asia into the Indian subcontinent. Some specimens have also been recovered in North America. This enormous range, spanning multiple continents, tells scientists that Dinofelis was highly adaptable and could thrive in a wide variety of habitats over its roughly four-million-year existence.

Question 7

When did Dinofelis go extinct?

Accepted Answer

Dinofelis survived from approximately 5.3 million years ago until at least 1.2 million years ago, though some estimates using Paleobiology Database data extend its range closer to around 11,700 years ago for some assigned specimens. The core of its known range puts its extinction in the Early Pleistocene, around 1.2 million years ago. Its disappearance likely coincided with major shifts in African ecosystems as grasslands expanded and large prey communities changed, along with increasing competition from lions and other large felids that were becoming dominant.

Question 8

How is Dinofelis different from Smilodon?

Accepted Answer

Dinofelis and Smilodon were both machairodontine saber-toothed cats, but they were quite different animals. Smilodon, which lived in the Americas, had enormous canines up to 11 inches long and a more heavily built body weighing up to 600 pounds in its largest species. Dinofelis was considerably smaller and had much shorter, though still elongated, canines. Dinofelis also lived millions of years earlier and across Africa, Europe, and Asia rather than the Americas. The two animals were more like distant cousins than close relatives within the saber-tooth group.
