Today Me and Roz hunted an exposure along the Trinity River near Fort Worth, Tx.  The recent heavy rains have scoured into the limestone (Fort Worth formation?), peeling away layers and spilling echinoids into the rocks below.    
Roz points to a
large echinoid.

What I found here
Next stop was a study of a Woodbine formation exposure in Arlington, Tx.
 
Next we hunted a small Grayson formation exposure not far away.  No photos were taken at this location.  We each found a fancy echinoid, Roz found the largest.
 
Next we visited a Pawpaw formation exposure in Tarrant co., Tx.  Nothing of note was found where we hunted.
