I finally took a trip to the North Sulphur river last week. There have been a couple good rains so I was hoping that would uncover some stuff. The last couple of trips in 2021 were terrible. All muddy and picked over. This trip was still pretty muddy and little in terms of quality mosasaur material. However I went low and found a lot of smaller material. I wonder if the recent muddyness of the river is due to the lake construction or if the river just hasn't had enough rain lately? Is picture 2 an enchodus jaw? I believe the pictures of item 3 are of a really chipped pi

The "big guy" to find at POC. Though, this one is smaller, the preservation is as good as it gets for this location. In fact, it makes me believe that POC could draw from layers adjacent to the Eagle Ford Group. I've found matrix pieces that are consistent with the geology of EFG, but need to find matrix pieces with this kind of preservation to confirm Atco or something else. I'm also not sure that this is C. crassidens anymore since this smaller, narrower form differs so much from the holotype. I currently believe it's an undescribed species since I haven't found something that ma-

Reconstructed tooth set from a "Crow" shark - Squalicorax (could be S. falcatus) - illustrating the variety of tooth positions. Anterior teeth have erect, triangular cusps. Lateral teeth and posteriors are more common and have an increasingly posteriorly slanted crown, resembling the teeth of modern tiger sharks. -
Found in Grayson formation Tarrant co, have searched and searched and finally came across Pseudoperna congesta, if that's not what it is I give up . Can't tell what they were attached to, assuming it's a mineral encrusting them? Or are they encrusting the mineral? My guess is it's some form of iron oxide, perhaps magnetite? Scale is cm.

Thought I picked up a little echinoid until I got home and put glasses on, thinking this is some kind of coral, perhaps micrabacia? From Eagle Ford.

From Grayson marl in Tarrant co, doesn't look like the other ptychodus teeth I have but don't know what else it could be. Really thrown off by the hole. Eager to learn it's identity.

I could probably fill the back of a pickup truck with ironstone I've picked up for closer inspection because it looked like it may have fossil possibilities, have only found a few and this is one. Found in Grayson formation Tarrant co, first thought was ammonite impression but there's a second faint impression on opposite side that doesn't fit with that and the outline isn't right, or am I not imagining the overall shape correctly?

Had a couple hours to hunt one of my local spots this evening… I didn’t find much, but I did manage to pull a nice little bivalve shell embedded over an ammonite imprint. cheers!

I am right now out in the field, attempting to extract a string of articulated reptile vertebrae in the lower Atco. It is in a soft marl bed just a few feet above the basal Atco. There seems to be articulated ribs associated with the specimen, and so far I have uncovered 14 verts. 9 of them were lose of the surface and bagged in ziplocks, but now I am trying to get the rest out. If anyone has any advice, I need it! The specimen also has articulated ribs. I want to get this thing home tonight, and not destroyed. This is is my first time attempting to extract vertebrae, and I want to

A bit of a vertebra theme tonight so thought I'd jump in, found this in creek in Cretaceous Eagle Ford but the area is QT and QAL also. It's not fully mineralized just like most bones from around here, I think it looks like croc but it's very worn so could be wrong.

Awhile back @Rockwood posted something similar to this and was given the ID Serpulid Reef, which I had never heard of until then. Would that be what this is? This is from creek in Eagle Ford, what's most curious is how the wad of spaghetti perfectly comes together at the mouth(?)end. Pictures I've seen of these reefs show worms poking out out in every direction.@erose

I recently found a construction site in a productive layer of the Eagle Ford. I found several ptychodus and other shark teeth as well as some pachyrhizodus teeth, a possible mosasaur tooth, and a couple of items that i cant figure out. Here are a few pictures of my finds as well as the items im not sure about. 1. The haul 2. possible Mosasaur or other reptile tooth? It is skinnier than a mosasaur and it is oval like as well so i cant figure it out. 3. I have seen this before on TFF but cant find the post. Anyone know what this is?

In my favorite creek with water levels so low there is a facinating little stretch exposed that is unlike any other part of the creek I've seen. There's about 100 ft of this grey marl in lower bank going into water, it's gritty, some still soft some like cement, loaded with gastropods, bivalves, and coalified wood. Running through it are the biggest calcite veins I've ever seen, some 10-15 ft long and almost pink, have no idea how far down they go. I was barely able to break a section off, this is part of one the smaller veins. Wondering if anyone has seen something similar. The other odd p

This is from Duck Creek formation in Tarrant county, not familiar with fossils from there so not sure what this is, looks very similar to a bacculite to me except for ridge running the length of it. Half cm long.

Collected some rocks from the Grapevine Lake area, however I'm wondering if these are from Woodbine or imported rocks? This is first time I've found any parts of an echinoid, I know some are spines but there are different ones, I recognize some of the other things but not all so numbered them. The last 2 pics I tried to get shot of tiny baby echinoids, there may be 2 in one pic but one looks exploded. There were so many things I couldn't even get them all but this will be good start.

I have no clue what this is, not sure how much is missing so that makes it hard along with still learning about the Goodland formation. Doesn't quite look like a gastropod or ammonite hopefully the little bumps are a clue someone recognizes.

Hello, Earlier today I found these two Fossil vertebra which I suspect are either Fish or Mosasaur or Plesiosaur, in a small gravel bank near some Texigryphaea. These are also my first fossil vertebrae. I found these two in the East Fork Trinity River in North Texas. And the two vertebra were right next to each other, probably two or three inches away from each other. I then looked later on the USGS Geological Survey and found that the Elm Fork Trinity River has holocene-era rocks, so then that rules out Mosasaur I guess? I looked online to see Mosasaur and fish verebrae to see if I could

Hi guys and gals! I found this mystery fossil a few years ago and the people I spoke to at SMU and the Perot are not sure as to what it is. I thought I throw it out here and see what opinions you all might have. Thanks for taking the time to look and try to help. Woodbine Formation : 95-98mya North Texas

This week's adventure for Rockwood and I was to the Duck Creek formation in Tarrant county, we found gobs of gastropods, echinoids, bi valves and peices of ammonite along with unknowns. Being unfamiliar with this formation I'm having trouble with some ID's, starting with these 2. I cannot find match for the oyster, maybe the ones I was looking at were worn down so I didn't recognize it I'm not sure. The impression really has me thrown off, the piece of shell looks like it might be what made it but I don't know what it is either. Appreciate any help

Hello, I found what I believe to be a sand dollar a little over a year ago in a small creek in the DFW area in North Texas. I checked the USGS Pocket Geology on my phone and it said that the area in which I found the sand dollar in was in the Washita Group in the Cretaceous, next to some Woodbine Group members. I recently heard that sand dollars first appeared in the Eocene or Miocene or sometime in the Ice Age. But as already mentioned, I found the sand dollar in a Cretaceous area. Is it possible to find sand dollars in Cretaceous-era rock? Is it a REALLY early sand dollar? Or is

I found this Echinoid a bit over a year ago in a creek in the DFW area of North Texas. I found this in the Washita Group of the Cretaceous. I thought this was a sand dollar, but I recently learned that sand dollars did not appear until the Ice Age era. I posted a question regarding the Echinoid on the discussions section of the forum and was told it was not a Sand Dollar. Anyway, I would like to know the species and classification of this flat Echinoid if anyone may know. I've never seen any Echinoid like it.

I have numerous worm tunnels, casts, an body fossils that are all very similar from Eagle Ford, then I found the one with black squiggles that is very different, is it just the preservation that is different or is it something else? The other one is from Grayson marl which I'm not as familiar with, the rather delicate branching structure has no resemblance to the worm tunnels/fossils I'm used to finding, is it something else or different species of worm perhaps?

I wonder if the baby shark song made outside the US, it's been stuck in my head since last night when I found the smaller of the 2 vertebra. Amazing I even spotted it, pretty sure the larger one is shark? Can anyone tell if tiny one is fish or shark? I'm trying to picture something so small, which shark could have babies so small? Could some shark vertebra be from babies still in egg sac? These were found in Eagle Ford, Cretaceous, the dark ruler is in mm.
