I found this partial nautiloid at Jacksboro. Finis Shale member, Graham Formation, Pennsylvanian. The odd part is how deep the umbilicus is. There was just enough of it to see a piece of intact inner whorl for the profile and some septa to know about how much bigger it could have been if an adult. There was also a piece of the flank broken back with tubercles. I made the clay model of what it might have looked like whole but left off most of the tubercles. I will add photos comparing it to a Metacoceras fragment of about the same diameter that shows the depth from the flank to the previous whorl being about twice as wide.

Went out for a couple hours last Sunday afternoon. Found a few things that I kept. One tooth I was a couple rains to late. One tooth was just in time because the next rain would have scattered down the hill. And the biggest and best tooth was lucky to see at all in last patch of dirt I was going to look at. Also collected a neat branching bryozoa. And a couple large echinoid plates.

Went out Sunday afternoon for about an hour to the Clay Pit in Coleman Co here in central Texas. Found the one tooth about 5 minutes after I got there so was a good five minute hunt about 30 yards from where I parked. The most complete one of these I have found.

I had a chance to visit Penn-Dixie today and one of my first finds stumped me. It has the signature porous inside of a bone. It’s black. It has radiating lines down one side. Folks running the place thought it was likely a piece a placoderm armor, making it a rare find. Apologies for the pictures. Once again I find myself in a hotel with my phone. Thickness is a bit over a quarter inch. Length is around 1.75”. Couldn’t make the phone focus well on the marrow. Does placoderm armor have marrow?

Ok I went out to the Wilson Claypit for a couple hours Sunday after church. Did not find much but a nice day. I found the two items below which have me stumped. I thought maybe interior structure of something maybe like Brachiopod or I don't know? Thought maybe interior structure from Crinoid or Urchin? Found the one with the two sides together then a 100 yards away found the other single. When I first noticed the one I thought it was interior of an old walnut but it is a fossil.

Last Sunday after church I decided to get outside for a little while. It was 38 degrees and windy but we had bought the grandkids some coveralls for Christmas so away we went. So my son and his two kids age 7 and ten loaded up and went out to a spot near Lake Brownwood to hunt some. This is an area we usually find lots of crinoid, gastropods etc but only occasionally find shark material. My son had his brain and eyes tuned in because he found 3 of the four petalodus pictured below. I just found the one small one. We did not find all the pieces but they went back together pretty good. He also found the hunk of cartilage. Of course the kids filled up a bag each of other fossils before deciding to start throwing them in the water was more fun.

Went out last Sunday for a few hours to a site north of Lake Brownwood here in Central Texas. We have had like 14 inches of rain over the last month so I have been wanting to go but this is the first time I have had. Found a couple of broken Petalodus and some echinoid plates to add to my reconstruction. Found lots of other stuff but left it for the next hunter.

In case anyone is interested in getting together, Quarryman Dave and myself will be at Penn Dixie this Saturday August 27th. We have been known to be a bit crazy and hard core in our collecting but generally we come away well rewarded. We'd love to see any of you that are in the area.

Spent a wonderful day on Sunday with my Fossil Forum Buddy Dave (Quarryman Dave) at Penn Dixie just west of Buffalo New York. After the normal hassle of getting fingerprinted at the border. We made an uneventful trip to the fossil site, although Dave did get lost at least three times trying to find the place. He only got lost once on the way back. Overall we arrived at 9:30 and left at 6:00. After a long day of splitting rock non stop we were very tired after the walk out to the car (which was past the closed gates) with buckets full of rock and equipment in hand. Met some great new people from New Jersey, you know who you are. Here's hoping we get to hunt eurypterids with you in the near future. Here is our work area for the day we created that bench and excavated about 50 square feet of surface area down about 24 inches. My estimate is that we were seeing about 4 to 5 trilos mostly partials per cubit foot we split. I suspect by the end of the day we found 50 to 60 trilobites with the potential to be complete (all but 2 phacops, I know they changed the name but I am old school) We found two that might end up being reasonably complete greenops but they are by no means perfect. The greenops tend to be in the more crumbly layer. Here is the overall group photo of what we found Here is a challenge to you , how many trilos can you see in this picture I gave up when I got to 50 A couple in here will prep up real nice. I will post pics once they are prepped. I put a few more pictures in my gallery as they don't fit here because of size restictions.
