Park near the Schimelpfenig library in Plano. The fossils are along the nortern bank of the creek. The fossils are mostly imprints of large clams (inoceramus?), but the matrix is very brittle and they cannot be collected.
Some of the clams are several feet long, and others the size of a quarter, and there are many layers of them in the exposed bluff. Some of them have thin sheets of calcite that formed like a second shell, and fragments of those can be easily collected.
There are also iron inclusions embedded in the cliff that may represent trace fossils of later burrowing clams.
Fossils: yes

 Meteorites: no

 Rock Types: bivalves, my best guess is Inoceramus.
