Jeffrey P, October 8, 2018 in Fossil Hunting Trips
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:
There were a number of Mariella, spiral coiled ammonites, and I also found a nautiloid, Cymatoceras:
Also found a few scallop shells. This is Neithea sp.
Bob also took me to a nearby site to hunt for brachiopods, Waconella waconensis:
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.
Bob found this huge echinoid he gave me:
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, 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:
A very special find was this crab carapace, Ferroranina dichrous:
Dan also informed me of a stream to collect ammonites:
Sure enough ammonites were plentiful, both in the streambed and in the embankments:
These are two of several Mortoniceras I ended up bringing home:
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:
He also found this partial fish skull which he gifted me:
I found this piece of fish jaw in three pieces which Kris thought might be Pachyrhizodus:
Great report, Jeffrey! Keep up the good work!
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:
There were also a number of bivalves:
