Both of these were collected in Grayson marl, is the small one a calamite? Hadn't occurred to me they could be found there. The larger one was 2 straight pieces side by side but the host rock is so fragile and part of top layer crumbled and broke them. Have not seen any burrows in Grayson so not sure if that's what they are.

Found this hunting new place at Woodbine/Grayson contact, there it was nestled in the lower layer of grey-blue marl sporting the same color. Last time I checked there weren't crinoids in Grayson, so how did it get there? Have only a handful of fossils this color from there including this bivalve I can't ID, or is it a brachiopod?

I came across this place not too long ago and recently made another trip, I am in love with this site, the colors, the layers, the in your face geology, the fossils, couldn't ask for more. Pocket map says this area is intersection of Woodbine, Grayson, and QAL. Showing in pictures the series of hills running east to west, #1 west end #4 east end. and various shots closer. Forgot to take picture of first hill on western side there was only Woodbine exposure that had layers of intense purple sandstone and what I'm calling snowflake selenite. The far east side was only Woodbine but in the middle hills were several layers of Grayson, top one was more yellow soft and crumbly, below a layer of more white and harder then below that all shades of grey and blue. Along the very top of hills you can see the red Woodbine. Will make separate post for Grayson fossils there are too many pictures, fossils, and questions. This is great learning opportunity so any additional information will be appreciated. Not too many fossils from Woodbine but it's visually difficult for me, everything is red black orange and blends together. Found gastropod, ammonites and various oysters being eaten by selenite but I like the sparkle, and bivalve #6, is this Pinna? Picture #5 was just a single odd place with sand balls. Found what I'm calling chocolate selenite and big chunks of rock imbedded with bivalves and encrusted in white, assuming it's gypsum? I liked the contrast in colors. Including picture of everything found.

Last week I visited my little spot in the Britton formation for the first time since all the flooding rains, it's only a small strip about 20 yds long that's slowly eroding but I always find things. There were the usual baculites, ammonites and crabs, an Inoceramus and a few I'm not sure about. The crab that's circled doesn't look like the other Notopocorystes, it's too long, is it lobster? Then there's the little baculite packed rock that had 3 tiny ammonites, #3 I pried off, Mortoniceras? #2 scaphite or Placenticeras? #1 so small not sure it can be ID'd. #4 separate rock looks like squished Allocrioceras with smaller one beside it? Pics will probably end up out of order so numbered ones in question.

Hello all, I spent the morning in one of our local creeks here in north Texas and pulled a partial ammonite fragment, a bivalve imprint and some sort of clam… With that said, I was wondering if anyone could help identify the clam species (last three photos) Cheers!

From the album: Texas Finds
Scientific Name: Enchodus? Found: North Central Texas Date Found: November 2021 Formation: Eagle Ford Size: 1.75" -
This also collected from Woodbine, looks like slickenslide in ways, the texture is on 3 different planes I circled the smallest one. This is so soft to touch you can't feel any ridges, it's so soft I thought the rock would be soft but it's very hard and where there's a chip it appears solid white underneath. It looks and feels like hair it is so fine and soft, so biologic or geologic?
-
Found in Woodbine if that matters, it looks structured but I think it's the makeup of the rock. Last pic is backside.

Collected in Woodbine which seems to be popular lately, never was quite sure what to look for and hope this is it, gotta be leaves right? Not sure what the cylindrical might be.

Found these in Midlothian, TX (North Texas) in 1 small area. #1 and #2 I'm most interested in identifying. Thanks in advance for those smarter than me who can easily identify these.

All of these came from a cliff face on lake Grapevine, no.1 both of these stood out because of rounded shape, plucked from the face of uppermost part of cliff. no.2 there was a thin layer of limonite running length of ledge, all was unremarkable I saw except this piece, thinking impression of plant material? no.3 assuming it's a concretion, thought it was an ammonite when it was cloaked in dirt, found in crevice with some gravels at top of cliff, doesn't look like Woodbine material so stood out, not calcite. Pics are out of order, first one should be last.

Need help to ID a possible fossil found in Post Oak Creek, Sherman, Tx
ThaGr8WiteDope posted a topic in Fossil ID
My son found this last week while poking around Post Oak Creek in Sherman Tx. The bumps and ridges on the sides are symmetrical, and it has a smooth hollowed out portion. Not sure if it’s part of a fossil or just an odd rock formation. Hoping someone here can help us out. Thanks!!

The receding flood water left lots of interesting things in my go to creek, it is in cretaceous Eagle Ford but I find a little bit of everything in it from recent to Permian to Paleo and imported rocks. This one is unlike anything I've found here so not sure what to make of it, at first I thought man made because of flat side but obviously not, kinda looks like sponge but just don't know.
-
Picked this up in Eagle Ford formation, don't know what to make of it, maybe algea, bacteria, mineral?

Hi everyone - I am a total newbie when it comes to fossil hunting in North Texas. My stepson has moderate autism and has always been into geology. I started looking for places to search for fossils as a way to plan fun excursions with him on the weekend. We started recently by going to Ladonia Fossil Park, Post Oak Creek in Sherman, and most recently, Mineral Wells Fossil Park. I am totally hooked! I was the one that didn’t want to leave, even in the oppressive heat! I am looking forward to finding new places and new fossils - so cool!!! I am fascinated by it all! Look forward to being a part of this forum!

From Woodbine formation, picked it because it looked like maybe something other than typical weird concretion, still does, but when I looked at little protrusion I saw what looks like part of jaw and something else. Had a heck of time trying to clear pictures, two teeth are visible and looks like rest broke off maybe. I'm guessing Enchodus?

I've been finding all kinds of strange things in this new spot in Woodbine, here's another I have no idea on. First thought was shell piece until magnification, pretty sure it's not, looks nothing like typical shells or preservation in the rest of rocks. It's kinda square, flat, and the black lines appear to be associated with it like antenna or something. Not even sure if it's plant or animal, looks bug like. Appreciate any help as always!
-
Collected this in Woodbine formation, I've searched through trace fossils but haven't found a match assuming that's what it is, hope it's recognizable.

From the album: Post Oak Creek
I'm pretty sure these are S. raphiodon teeth. They are much smaller than S. texanus with a narrow main cusp and finer striations than S. texanus. Compare: http://oceansofkansas.com/sharks/Kansas/shscap3.jpg -
From the album: Post Oak Creek
I'm fairly certain this is a posterior Cretodus - a shark known for producing Texas-sized teeth! At just 1 mm tall, this may be the smallest Cretodus tooth possible. -
From the album: Post Oak Creek
The famous "ginsu shark" is a rarer species that can be found here. This is a lateral position; a tooth farther back in the mouth. I've only found a handful and none are complete. -
From the album: Post Oak Creek
Symphyseal teeth are found in the midline of the shark's jaw. They are usually small and squashed-looking. Since only a few rows produce these teeth, they are much rarer than other positions.
