This one evolved because a talented young taxidermist named Brian Geer (who works for Nature's Design Taxidermy in Cody, WY) got hold of a liger pelt. Ligers are tiger/lion crosses; their hides may resemble those of Smilodon, and they're about the right size, so it seemed only natural to create a sabretooth. There are hundreds of Smilodon skeletons to draw from, so it was no trick to get the size, weight, and musculature down. The tusks are cast directly from fossil teeth. This cat is, I believe Smilodon populator, the medium-sized variety that was found in North America, and in a well-fed state he would have gone about 620 pounds.
