This is a fossil and geological field trip to Mineral Wells, Possum Kingdom,
and Graham, Texas.
First stop was a small outcrop near the
Pennsylvanian-Cretaceous boundary along Hwy 180 east of Mineral Wells.
Nothing of interest was found except unidentifiable fragments of shells
AND a rattlesnake!.
This area represents some of the oldest
Cretaceous (Twin Mountains Formation) AND Pennsylvanian Period (Garner Formation?)
deposits in the area. |

Next stop was the dramatic road cut east of Mineral Wells.
Here the road briefly splits east bound and west bound around a hill.
The south lane is much lower in elevation and reveals how the hard
sandstone is sitting on top of shale.
This is the Mineral
Wells formation. No fossils found. |
