Daniel Aguilar, lead Palentologist on the Tomayate River project, counts the vertibrae on the remains of a Giant Sloth found near the river 15 kilometers outside of San Salvador, June 25, 2001. The site was discovered by a handyman in April and has yielded the largest deposit of pre-historic bones in Central America. 22 species have been uncovered to date including Mastadons, a Sable Tooth Tiger and a Giant Armadillo. The results of Laser-Argon testing suggest the bones are 8.5 million years old, leaving paleontologists to conclude that the land bridge of Central America is up to 6 million years older than previously believed.
