Pleistocene Era (:55)
Prehistorical animals from the Pleistocene Era (2.5 million to 12,000 years ago) lived in the Alvin area. Fossils from this Era were found in a 25 foot-deep sand pit on the Winston Dairy property, northwest of Alvin. These fossils were studied by a local paleontologist and confirmed as authentic by the Houston Museum of Natural Science. They were identified as a half portion of a mammoth tooth, the tusk of a baby mastodon, and teeth from a bison, a sloth, and a horse, along with the shell of a giant tortoise. The coastline was 150 miles further offshore during this Era.
The horse tooth was from a species which died out during the Ice Age. The horses we have now all came from Europe.
