Solving the Mystery of the First Animals on Land: The Fossils of Blackberry Hill
- Publisher : Siri Scientific Press
- Illustrations : 81 col photos + col illustrations
Description:
This is the first book to cover the unique group of rock outcrops in central Wisconsin that appears to have put an end to a 150 year-old mystery of global interest. Since the mid-1800s, fossilized trackways and footprints have been found on beach deposits that date back to the Cambrian Period, some 500 million years ago in what is now North America – but fossils of the animals that made them were reluctant to reveal themselves. Thanks to Blackberry Hill, the identity of some of the first animals to walk on land is a secret no more.
