Tarrant County, Texas
July 7, 2007

I hunted a Pawpaw site in Tarrant County, Texas and found some shark teeth and crab bits.  
Leptostyrax macrorhiza and
Cretalamna appendiculata
teeth.
Nephrops americanus claw parts.
At another site I found a very nice large echinoid, oyster, and ammonite.  
Macraster sp. echinoid.
Drakeoceras sp. ammonite.
Amphidonte walkeri
(Exogyra americana).
