I got to visit a site today that isn't often open for collecting and found over 250 crinoid columns for the kids. The longest was 75mm and the biggest around was 17mm. This piece of shark cartilage may be a gill arch section. This crinoid cup has a lot of articulated plates for North Texas and I find even fewer of these arms. This is the first example of a gastropod in the Platyceratidae Family I've found. Platyceras parvum.

Polly M. is the fieldtrip leader for the Dallas Paleontological Society. She found this Pennsylvanian Period snail and we don't know it's name.

On Memorial Day weekend in 2015, my dad and I took a fossil hunting trip to Brownwood, Texas. One of our destinations was the Wilson Clay Pits. We discovered lots of great pieces, which I will eventually get around to posting. But one specimen has been floating in the back of my mind, and I would like some help in identifying it. At first, I thought it looked like a shark tooth, with the three sharp points. But then I decided that it might be some sort of crinoid calyx plate. Still, I have never seen a crinoid calyx plate with the three spines. Looking at examples of Peripristis sp. make me lean back toward a shark tooth. I anyone has a suggestion, I would be very grateful... Daniel

I have done quite a few searches and read crustacean papers but I cannot reach a conclusion. It was suggested that it may be an arthropod, maybe crustacean. Does anyone think that this looks likely for arthropod? It was in a nodule. It is from the Pennsylvanian Period. Thanks for looking!

I don't trust my vision with this one. I think I see a few small round teeth on the lower part. Pennsylvanian Period, Texas Thanks!

I am not even sure it's a fossil but it's shape doesn't seem random to me. I have never found any soft bodied fossils before that I am aware of so I am not sure.. Pennsylvanian Period, Texas (Images are of both sides of the nodule)..

I have been hoping to find a jaw with teeth for so long. I have a scrap pile while I put matrix pieces that have nothing interesting in them. I decided to hammer open some of the scraps.. It to great delight and surprise I could see what looked like teeth with my loupe but still could not tell until I took pics. The size of these teeth is very frustrating as it is so hard to try to get pics that are half way clear.. Here are the best of the shots. I am hoping it can be identified.. My theory is this jaw is the same type of fish as one of the heads I've found. The last shot is on the negative side. Thanks!

I was going through some fossil containers that I haven't looked at in a long time. This came from a fossil hunt in 2009 and I noticed a tiny nodule I had picked up. I opened it the other day.. It is Pennsylvanian (upper carboniferous) and from Palo Pinto County, Texas.. At first I thought it might be a hackle fracture but once I took pics I could tell it wasn't. I am hoping someone might know.

This is a small bone that I found recently.. It is from the Pennsylvanian Period, Texas. I was really excited when it first opened because I thought those were teeth in the center but they are not. They seem to be fused together.. I thought someone might recognize it from something they have found.. I think it is part of a fish. The first shot is for size only with all the other shots through my loupe.. This shot is the negative side The rest are different views of the positive side

Thanks to trip leaders Polly and North Sulphur River King... Jacksboro is in the Upper Pennsylvanian, lower Graham Formation.. My best finds were two great Orodus teeth, a shark spine and a mystery tooth.. If anyone can ID the round mystery tooth it would be much appreciated.. The tooth below is the one that I could use help with.. That's a penny underneath
