Pierre Shale - Pueblo, CO
This site is on PRIVATE LAND. I was privileged to hunt on the mesa with the express permission of the owner.
Although on private land, the owner of Baculite Mesa allows collecting for personal use on a limited basis with pre-approved permission.
In this area, the Pierre shale is a loose muddy shale, punctuated outcrops of hard rock.
The terrain is quite barren. Water and sun protection is essential on hot days.
This is typical of the baculite fragments which give this area its name.
These hard rock formations poke up through the muddy shale and are fossiliferous.
Some of the outcrops are full of bivalves of several different species.
There are no fossils in the red outcrops.

Baculite Fragments of the Pierre Shale
These are the fragments I took home after about 2 hours of hunting. I left many more in place.
Bivalves of the Pierre Shale
At least three different bivalves are present. The only other fossil I found was a small gastropod in matrix.
