The fossil bearing layers are exposed in the washes and gullies just past the parking area.
The layers are a yellow/brown colored mud. The fossils wash out of the mud onto the surface.

Fossils from Conger Spring
This represents about 2 hours of hunting by the two of us. All of the fossils are small.
The crinoid stem fragments are by far the most abundant fossil. We also found a number of calyx plates and parts.
There are several species of bivalves as well as horn coral and byrozoans.
This site is worthy of a half day.
Happy Hunters
