About This Piece

Slimy Shoreline
Roxborough State Park
250 million years ago

The Permian extinction destroyed most of Earth’s marine species just over 250 million years ago, and a lot of life on land as well. At the time, there was beachfront property in Colorado. The post-extinction Colorado coastline was home to single-celled bacteria and algae, living together in mounded colonies known as stromatolites.

The Lykins Formation consists of cream-colored layers of wavy limestone amid thick piles of brick-red mudstone. The thin limestone layers—remnants of ancient stromatolites—stick out like short, white walls at Roxborough State Park.
