I think this is a skull fragment, but I cannot figure out from what. Found in the North Sulphur River near Ladonia, Texas. Found in a pile of gravel and rocks in the center of the river bed. No other associated bones were found. I labeled the photos Back, Front, Top, Bottom (Because thats what they look like to me). Any help identifying it is greatly appreciated. Back View. Front View Bottom View. Top View.

I was recently able to hit a tributary of the Sulphur River and came out with a crocodilian tooth. Otherwise it was a good trip, but not great like I had hoped. I do video better than photos and text. Here is the link. Can I ask a favor???? watch the first minute of the first video, and then the second video(1 min intro 2.0). Is the first intro so bad (shaky camera, uncomfortable camera angle) that I should try and replace it? How's the second video as a replacement?? i really appreciate it!! http://youtu.be/i_ZKC9QlAOE test intro: http://youtu.be/YJ69Xp5Zkmc

Pretty good variety this morning after a few big rains.

I have a bunch of petrified/coalified wood from Mazon Creek and have started a process to decrease the reactivity of the pyrite and sulphur in them. Thought I'd describe the process and results in case it is helpful to anyone else. Some of them are fairly quick to form decay and even create lovely hairy crystal gardens of possibly Pickeringite or Halotrichite. Here is an earlier post about that. Here's some images of the cool crystal hairs that formed awhile back. Anyway here's my process that I've started on a few items. Not at all sure if this is the best process but thought I'd try it as an experiment and see what happens. It is an adaptation of recommendations by Reiner Mielke. Any suggestions or critiques would be great. I'm currently at Step 4 with the first batch and debating about Step 5. Step 1: Neutralize in water with some baking soda. (I notice my pieces really fiz a lot and some of the material breaks a part in this reaction so one may need to be careful with fragile items.) Step 2: Dry in the oven at low temperature for several hours. Step 3: Immerse in WD-40 to displace all the water. Step 4: Let dry Step 5: Two options and I haven't decided between the two: One option is to immerse in motor oil. (This is the Mielke approach) The other option is to spray with Fluid Film (a lanolin product in a spray bottle to prevent rust) Then let dry.

Sunday I picked up my old bud trentonmon and we headed east. We dropped into the North Sulphur River at several locations and found a few goodies in the Taylor group Ozan formation of North Texas. We saw the ruins of the old railroad trestle near Camp Shed or Enloe. I found a number of reptile and mammal verts and bone frags. One spot provided most of the fish and shark teeth pictured. I found a nice globbidens Mosasaur tooth, assorted enamel flakes along with a couple of mastodon fragments. One arrowhead, a blank and what must have been a scraper or blade. Worm tubes were everywhere. I picked up 80 of them. I have a small clamp lid jar I want to fill with them...and I am getting there with that project. My buddy trentonmon had a pretty good hunt too. I hope he will post his. He found a huge cervical mosasaur vert and more of the same goodies I found. All in all a pretty good outing. The weather was just great. Trentonmons bday was Saturday so I got to rib him all day about getting so old. We had fun, got in some serious exercise, and put yet another adventure in the bank and you know what if I had a dollar for all of the adventures he and I have had over the last 43 years I could really go to the bank. over and out wfrr aka Randy Rogers

I keep finding these at the NSR (found 3 more yesterday) and haven't been able to get an ID on them. I've posted pics in the past without any response so I thought maybe they were just anomalies but then I kept finding more and more of them and they all seem to have the same shape and markings so they're 'something'...but what? I shake my head and laugh every time I find another one because I can't figure out what they are...tooth, bone, tooth & bone...??? Definitely not a rock so I keep collecting them regardless. Any thoughts or ideas?

N Sulphur River Id Help Please...bare With Me...still Trying To Learn This Stuff :-/ (Part # 2)
MFowler posted a topic in Fossil ID
Here's 'Part #2' which is teeth I can't ID. I know some of these are Enchodus, but several of them seem different so I'm not sure if they're just variations of Enchodus or possibly something else. Also, there may be some Mosasaur teeth or pieces of teeth in here as well...but I don't know. Thanks again everyone, Mark

N Sulphur River Id Help Please...bare With Me...still Trying To Learn This Stuff :-/ (Part # 1)
MFowler posted a topic in Fossil ID
I've only been doing this since March and I still have trouble ID'ing a lot of things so please have some patience with me. I've gotten to where the teeth (shark & other) seem to find me...which is great cuz that's my favorite thing to find. I also can spot bone pretty good now, but can't tell ya what it's from. I've got a lot of teeth and bone that I've found since March, but outside the shark teeth and obvious vert pieces I'm still trying to figure out what bone/tooth belongs to what. Anyway, I'm A LOT more knowledgeable now than I was in March and now know 'what' to look for...the problem is, outside of shark teeth, ID'ing this stuff is pretty snarge hard. Not deterring me one bit though...eventually I plan on being one of the people on this forum that can help ID stuff for the new addicts like me :-) ***I'm posting bone pieces here I can't identify...I'll post a "Part # 2" that has some teeth I can't ID after this.*** Thanks to all of you for all the help...now and since March, Mark
