| Today I explored a couple areas in Jack County, Texas.
Nothing very exciting was found but I did find some broken but mostly
complete examples of Heliospongia sponges. |
Location 1
 |
Crinoid bits
 |
|
| This location just northeast of
location 1 is either in the Colony Creek Shale or the Thrifty-Graham Fm. |
Location 2
 |
Crinoid bits
 |
Trace fossil
 |
| Location 3. This location
in the Placid Shale
produced nice examples of Heliospongia sponges. A week later on
2 Feb 2020 I went back to collect more. |
Location 3
