Next day was Cretaceous. Drove an hour east to Denton and met up with BobWill who showed me the Rayzor Ranch site. It is a commercial development and there are piles of debris from the Grayson Formation. There were oodles of small oysters, Ilymatogyra arietina:

Also found a few scallop shells. This is Neithea sp.

Bob also took me to a nearby site to hunt for brachiopods, Waconella waconensis:

Great topic! Can’t wait to see the rest. Texas Cretaceous is right up my alley, but so is all of Texas geology.

 

Jacksboro is really a special place. I have only been there once so far (back in May), but came away with tons of gastropods, crinoid segments and stem pieces, bryozoa, nautiloid and ammonoid pieces, including some tiny and exquisitely detailed pyritized goniatites. No compete large goniatites though. Hope to go back soon. Bob is good people and is the best to show you around the site, as he was when I went with him there. 

 

Again, great trip report!

Inoceramus (clams) were also plentiful:

Dan also informed me of a stream to collect ammonites:

Sure enough ammonites were plentiful, both in the streambed and in the embankments:

After two days of collecting solo, I met up with Kris, Ptychodus04 and his friend, John and explored a streambed that exposes the Britton Formation.

Kris gifted me a pair of fish vertebrae:

I found this piece of fish jaw in three pieces which Kris thought might be Pachyrhizodus:

We then visited a stream which exposes the Early Cretaceous Goodland Formation:

Gastropods were plentiful: I found severeal and John and Kris gifted me more as well. These are Tylostoma:
