The most prominent feature of Smilodon was its large canine teeth, which protruded from its upper jaw and could measure as long as 11 inches in the largest Smilodon species (Smilodon populator).
Smilodon was comparable in size to big cats of today – lions, tigers, jaguars and leopards – but it was built more heavily. It had a short tail and short rear limbs, while its front limbs were longer and its shoulders were raised much higher than the rear portion of its body.
The fur coloration and pattern of Smilodon is not known. Whether it had a mane, spots, stripes, or other features found in today’s big cats can’t be determined by available fossil evidence, but all are in the realm of possibility.
