This bone is almost identical to mosasaur bones found in the NSR, despite being from a different formation a few million years older. -

Hey y'all! Was wondering if I could get some help ID'ing this tooth that I found in Post Oak Creek this evening. I asked the Dallas Paleo Group on FB and a couple of people said it looked maybe human (also pig), but I am not that lucky lol (not that I am saying they are wrong or that I don't value their ID! I don't know enough on the subject to draw a conclusion) I thought I would come here for some second opinions <3 Please ignore the dime. And thank you in advance. I fully expect it to be a deer or cow or something xD (I only just posted in the FB group about an hour ago so the discussion

Found this crazy polka dot shark tooth in my Post Oak Creek Matrix! I wasn't sure what it was at all until I got pics.....it's a bryozoan! It arched a little over onto the back side! It's been a Bryozoan kind of week....found this cool critter in the Glen Rose Formation. I put it in my "Big Uglies" collection - a Chlamys bivalve with lots of other organisms on it....including this interesting bryozoan!

Post Oak Creek Microfossil Matrix for Trade
ThePhysicist posted a topic in Member Fossil Trades Bulletin Board
I'm offering for trade about half a gallon of microfossil matrix collected from Post Oak Creek, Sherman, TX. It's rich in marine fossils from the Late Cretaceous Interior Seaway (Eagle Ford Group ~ 90 Ma). I cannot guarantee what you will find. I however can comment on what you can find based on my experience with this site. Sawfish oral teeth are very common. You may also find a variety of sharks' teeth, with about 8 genera that I've found so far in similar matrix (Squalicorax, Cretoxyrhina, Cretodus, Cretolamna, Ptychodus, Scapanorhynchus, Hybodus, Cantioscyllium, ...). Reptile teeth are unc -
I went back to a new spot on POC and found the typical array of broken shark teeth, a few Ptychodus teeth, and some interesting items I'm not really sure about. Anyone have an idea of what the item in pictures 6-8 are? What about 9-11 maybe coprolite or a fossilized crustacean? The item in pictures 12-14 appears to be a tooth but with no enamel I didn't think it was a shark tip. It could also just be a piece of bone or something. Sorry for the poor picture quality of that one but I will take better ones of it later. Im pretty sure picture 15 is a rudist and lastly the item in pictures 16-18 I

A lot of what I learned from the trip, was learned here on the Forum. Thank you very much!! Went 1/2 of a day on Saturday, and 1/2 Day on Monday. 5 hour drive from South Texas but worth it. Made the trip with family, they have finds of their own. Not sure of what I have found here. Any help with identifications would be appreciated. The shark teeth are in rows of 8. Part 2 and possibly Part 3, will be posted later plus our first trip to NSR!!

Here are my son’s finds. Turns out he found more than me and had better representative teeth. He had a real good eye on finding them, even without the strainer pan. My “readers” would not let me do the same. That is my excuse, lol.

Found this little critter in my Post Oak Creek matrix. I'm guessing fish tooth? Thanks for any info! (I'm including lots of pictures because it is just odd from all angles) It's 6mm Top View Opposite End Underside Topside

I made a trade with a fellow Texas fossil hunter - sent him some Central Texas goodies for some North Texas Post Oak Creek gravel. I was hoping to get a gallon bag to look through in my microscope.....and he sent me FIVE gallon bags full of just scooped up out of the creek gravel! So far I've made it through ONE and a half of those bags! It may take me the rest of 2020 and right on through most of 2021! So I thought I'd post some of the good stuff I've found so far. Starting it off with THE TEETH. There were some larger teeth, nothing great, no ptychodus, which I was hoping for, but the mini

Nice array of colors. The biggest one here is the largest I've found to date at about 5 mm in its longest dimension. -

Very narrow tooth with serrations indicates it must be Squalicorax sp. -

Here are my finds from my latest POC visit. Made a decent haul with my best Ptychodus yet and my largest tooth so far here. The tooth was about 1.5 inches. I also found a small ptychodus with no root but it did have very defined grooves. Pictures 2 and 3 are the large Ptychodus and picture 4 is the 1.5 inch tooth. 5 and 6 are the small Ptychodus. Picture 7 is the creek wall matrix I was looking in for teeth and 8 and 9 are the actual teeth I found in the matrix. Does anyone know if this is original matrix? I was able to find several teeth sticking out but several of them were also just pieces
