Fossil crocodile tooth is a first for Wisconsin

Published on June 14th, 2009 | by Admin


A fossilized crocodile tooth found in Wisconsin could be the first evidence that vertebrates lived in the area during the dinosaur era.

The species of crocodile can’t be determined from just the tooth, but previously no known vertebrates had lived in that ancient period in the state. The find, five miles east of River Falls, would be most intriguing if it originated from a creek bed or bottom, said Mike Middleton, a UW-River Falls geologist.

However, “It could have been dragged here by a glacier,” he said. To verify which is the case, he and other researchers will check the site for a particular type of exposed rock in the banks of sediment. Officials have been anxiously awaiting warmer weather so the search can be done – probably in July.
