re: **deltra u there **** Smilodon fatalis ("the deadly Smilodon") is the best-known of the sabertooth cats. It appeared in North America about 1.6 million years ago and later migrated down the west coast of the continent to Peru. It became extinct around 10,000 years ago. Smilodon fatalis ranged in weight from 600 to 800 lbs (272-363 kg) and ranged in height from 39 to 47 inches (100-120 cm).
