This day me and Roz hunted 10 spots around Mansfield and Fort Worth, some are not shown here. 

First stop shown here was the Eagle Ford formation "Mansfield Pit" which had yielded SO many pristine shark teeth in the past.  Unfortunately the area is now under construction and the heavily eroded ridge that the teeth came from has been totally flattened and the dirt moved elsewhere.  We only found a few battered teeth.  [Photos updated 21 Aug 2022]
 
Next stop was a Grayson formation is west Arlington. 
The exposure is on the other side of the vacant lot.

Next was a small Pawpaw formation exposure east of Fort Worth.  Nothing of note was found. 
 
Next was a large Fort Worth formation exposure north of Fort Worth.  Here are some large echinoids, large oysters, pectens, and ammonites.

Next was a Pawpaw exposure north of Fort Worth.  The temperature was around 100 degrees which was affecting our ability to hunt.
