This creature lived in the Oligocene e.

This picture shows various bones of the skeleton of Hoplophoneus. Note the skull with its saber teeth in the center of the picture. The canines have a sharp bend and fit into a groove on an expanded process on the lower jaw: a feature seen in other sabertooths but not in Smilodon. Note also that Hoplophoneus was a relatively small cat.

The skull is only about 15 cm long. Hoplophoneus was roughly the size of a bobcat, or about one and a half to two times the size of a housecat. Also of interest is the web exhibit, "Cats!

Discover , April, pp. This differs from a previous microwear study using a different technique that concluded saber-tooth cats avoided bone to a far greater extent.

The researchers examined how these patterns changed over time by selecting specimens from tar pits of different ages, ranging from about 35, to 11, years ago. If anything, their analysis suggests that the proportion of the carcasses that both kinds of cats consumed actually declined toward the end. The researchers acknowledge the high rate of tooth breakage reported in the previous study, but they argue that it is more likely the result of increased breakage when taking down prey instead of when feeding.

Species like hyenas that regularly chew and crack bones of their kills are as likely to break the rear teeth they use for chewing as their front canines. Species like the cheetah, however, which avoid bones during feeding are twice as likely to break canines than rear teeth. This suggests that they are more likely to break canines when pulling down prey.

The researchers report that previous examinations of the jaws of the American lions and saber-tooth cats from this period found that they have more than three times as many broken canines and interpret this as additional evidence that supports their conclusion that most of the excess tooth breakage occurred during capture instead of feeding.

In addition, the researchers argue that the large size of the extinct carnivores and their prey can help explain the large number of broken teeth. Paleontologist has been studying them for years and has been working out on various theories that suggest reasons for Why did the Saber Tooth Tiger go Extinct.

We have gathered all the theories here to give you an overview of all the possible reasons for saber tooth tiger extinction. It has been observed that big cats tend to consume the complete animal they hunt when food is scarce.

This behavior has significant effects on the wear patterns on their teeth as they chomp the bones for a longer period. Based on this behavior of big cats, paleontologists studied the teeth and formulated the theory on why did the Saber Tooth tigers go extinct. At the time of saber tooth tiger extinction , the ice age was ending. Glaciers were melting, changes in seasons and rainfall occurred, causing a disturbance in the local ecosystems.
