Jeffrey P Posted October 8, 2018 Author Share Posted October 8, 2018 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: 2 Link to comment Share on other sites More sharing options...

Jeffrey P Posted October 8, 2018 Author Share Posted October 8, 2018 Later that day, Bob took me to his neighbor's ranch. It was a wild bumpy ride in Bob's old pick up truck across fields with cattle. We arrived at a stream bed. Within the first five minutes I found and collected this Eopachydiscus. It was too heavy to carry so I left it and picked it up on the way back. 4 Link to comment Share on other sites More sharing options...

Heteromorph Posted October 8, 2018 Share Posted October 8, 2018 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! 3 Link to comment Share on other sites More sharing options...

Jeffrey P Posted October 8, 2018 Author Share Posted October 8, 2018 Dan, Uncle Siphuncle and I were supposed to meet up, but a family commitment prevented it from happening. However, Dan was generous in giving me directions and info. about three sites in the Dallas/Fort Worth area. He was my spiritual advisor on this trip: The first site; in the Britton Formation produced a number of baculite pieces, Sciponoceras: 5 Link to comment Share on other sites More sharing options...
