American Lion (Panthera Leo Atrox)
Age:
Pleistocene
Classification: Family Felidae
Note:
Panthera Leo Atrox. Pleistocene La Brea. This extinct lion was
found in throughout North America as well as northern South
America. It had sharp retractable claws and sharp teeth
(shorter than those of other extinct cats). The most well known
fossils found were out of the Rancho La Brea tar pits in Los
Angeles, although some were also found in Alaska. Other
subspecies of the American leo can be found today in parts of
Africa and in western India.

Dire Wolf Baculum (Canis Dirus)
Description:
The dire wolf was a large canine that exhibited hyena like
characteristics. Like the hyena, the dire wolf hunted and
scavenged for food. Researchers suspect that dire wolves, due to
their scavenging nature, scattered the bones of animals they
killed or that were killed by other prey. The dire wolf was not
quite like any animal we have today. It was similar in overall
size and mass to a large modern gray wolf. (A popular
misconception is that dire wolf dwarfed the modern day grey
wolf) It was about 1.5 meters (5 feet) long and weighed about 50
kilograms (110 pounds) on average. The dire wolf looked fairly
similar to the modern gray wolf; however, there were several
important differences. The dire wolf had a larger, broader head
and shorter, sturdier legs than its modern relative. The teeth
of dire wolf much larger and more massive than those of the gray
wolf. The brain case of the dire wolf is also smaller than that
of a similarly-sized gray wolf. The fact that the lower part of
the legs of the dire wolf are proportionally shorter than those
of the gray wolf, indicates that the dire wolf was probably not
a good a runner as the gray wolf. Many paleontologists think
that the dire wolf may have used its relatively large, massive
teeth to crush bone. This idea is supported by the fact that
dire wolf teeth frequently have large amounts of wear on their
crowns.

Cave Bear (Ursus Spelaeus)
Classification: Family Ursidae
Description:
The
herbivorous cave bear was essentially a European species. It was
named after the places where its remains are commonly found:
caves, in the Alps, the Ardennes, the Carpathian and Ural
Mountains, and in many other European mountain chains. This is
where the animals hibernated year after year, and where they
often died. The
cave bear and its competitor, the brown bear, had a common
ancestor, called Ursus etruscus, that lived nearly 2 million
years ago and was already in part herbivorous. The oldest true
cave bears appeared some 300,000 years ago. The individual size
of the animals gradually increased, although a tendency to
diversification sometimes produced relatively small forms. Apart
from their usually larger size, cave bears differ from brown
bears in the form of their skull, their reduced dentition and
the size relations between their limb bones. In the larger,
western part of its range, Ursus spelaeus populations declined
after about 40,000 years ago and in the end did not survive the
Last Glacial. Competition by the brown bear and hunting by man
may both have played a role. In the western Caucasus some held
out a few thousand years longer.
