Johnson County, Texas
Oct. 19, 2008

Today Me and Roz hunted two spots in Tarrant and Johnson counties.  First stop was a Mainstreet formation construction exposure that produced good stuff last time.  
Roz finds a rare Lamellaerhynchia brachiopod
   
Next stop was an upper Grayson & Woodbine formation exposure. 
Heteraster echinoid and crab claw from the Grayson portion
Possible shark cartilage from the Woodbine portion.
