Carnivore fossils are incredibly unusual, however, in contrast to those of their victim. Prey are constantly more plentiful than predators in a healthy community. So the possibility of burial, storage and discovery of predator bones and teeth is for that reason slim compared to those coming from herbivores.
Scientists have a fairly little and scattered stock of sabertooth fossils. The exception originates from Rancho La Brea in downtown Los Angeles, where over 1,000 individual sabertooths were bogged down in tar-seep death traps.
That’s why the recent discovery of a charming sabertooth cat skull in southwestern Iowa is so amazing. The Smilodon fatalis skull was gathered from late Pleistocene sand and gravel exposed along the East Nishnabotna River. My coworker, biologist David A. Easterla, and I are studying this specimen to learn more about the biography, victim choice and ultimate termination of this ancient predator.

Clues from a cranium
The animal’s typical name – sabertooth cat – originates from its extremely distinct, saberlike canine teeth that poke out of the mouth as much as 5 or 6 inches (13 to 15 centimeters).
Sabertooths are sexually dimorphic, with males generally larger than females. The Iowa skull is bigger than those of lots of men from Rancho La Brea. Several bones of the skull have actually not sealed together and the teeth are essentially unworn, leading us to think this person was almost definitely a young male in between 2 and 3 years of ages that was still growing.
We price quote he weighed 550 pounds (250 kgs). That’s upwards of 110 pounds (50 kgs) higher than the average adult male African lion. Given a couple of years to grow and fill loose skin, he may have tipped the scale at 650 pounds (300 kgs).
