A few weeks ago I went snail collecting in a drainage canal that is in an outcrop of Eagle Ford - Britton formation , haven't been for awhile and there was a lot of erosion that changed things up. This area must have been very shallow Ive only found a few small ammonites and baculites the majority of finds are crab concretions. This time however no concretions, but various crab parts with unusual preservation of certain things First up want to confirm ID of Cenomanocarcinus vanstraeleni and is that an eyeball? The carapace is a little wonky and missing some but it's definitely round. Also showing area where it appears shell was ripped away and that's what's left.

This was collected in same place as #1, half is missing but it didn't get crushed, hard to tell where concretion stops and crab starts and not sure if it's going to get ID , only two bumps and not sure what to make of them It looks like parts were pushed up into cavity that don't belong there but what are they? Im assuming mouth parts? One little piece came off when I was cleaning it.

Collected in same place as 1 and 2, I'm assuming this is Ferroranina dichrous (formerly Notopocorystes) going by the only section of carapace which is calcified. I was really confused as to what I was looking at when cleaning it and had to do a little research on crab anatomy. This one breaks all the rules and looking forward to an explanation of how this was possible. #1 showing carapace, #2 heart, #3 gill, #4 I believe is calcified flesh, #5 cardiac and pyloric stomach (I think) , 6,7,8, and the rest are open for interpretation. #5 was most fascinating and took pictures from different angles with different lighting.

Thought this was a burrow of some type but it didn't add up and after seeing the possible preservation of other fossil I'm thinking this might be an appendage, minus the shell, looks like where something was pulled from socket on one end and disconnected on other. I'm expecting a different explanation though

Went to check out creek level and look for stranded fish and picked up couple things at the water line. Creek is in Eagle Ford formation, Cretateous. Don't know if there's enough bone to determine anything, it's completely mineralized, doesn't quite look like the usual turtle shell piece but thought it might be recognizable. Would the rock be banded chert? I haven't seen it except in small pieces, is this how it is formed?

Set out yesterday morning to dig up seedling blue bonnets in area by a gulley I hunt, haven't been there for a year so thought I'd check it out before it started raining. I think this is an outcrop of Britton formation, Eagle Ford. Didn't get far before it started raining so basically filled my bag with globs of clay for most part then proceeded to clog up bathtub washing it all off. Pretty happy with results, wish I could find whole ammonites the preservation is so good, was tickled with two Inoceramus that had some shell. So mystery #1, I'm stumped and afraid to chip at any more not knowing the rest of shape. #2, not sure if the piece of shell is related, looks an awful lot like a ptychodus tooth but I'm sure it's something boring Threw in last one just curious what it could be.

Cretateous oyster from Grayson formation that I need to mark off my list. Largest oyster I've found, both valves present, weighs half a pound, but umbo and beak are obliterated so undecided. I think Ostrea when I see ruffles. And now Gryphaea are going by Pycnodonte? They stick an e on the end of fish name and it's an oyster now? Why do they want to confuse us more

I was cleaning up these ammonites from the Grayson formation and something popped out of one and another thing came out of matrix. My cataracts are making hard to see small details even in pictures so want to confirm what I think I see, a regular echinoid and maybe a gastropod? Thanks for helping my eyes

Don't think it matters but this is a Cretateous crab, don't think I've ever seen a crab that wasn't in what I'm assuming is a moulting position so curious what's going on with this little guy. Was it maybe dead and floating or perhaps trapped in the sediment and struggling to get out?

I want to call this coral but doesn't look like any I've seen from Texas, maybe it's the size and being agatized that I don't recognize it. Tabulate coral or rudist maybe? Found in mostly Cretateous Eagle Ford creek.

This was collected in creek that's primarily Cretateous Eagle Ford with some Woodbine mixed in, closest thing I've seen is accretionary lapilli but don't think that would be here, maybe something algae related? Other side has lines that resemble roots and you can see little holes where the spheres are imbedded but not sure if the two are related. Last image is side shot. Any ideas?

Found this nearby my house in a rockpile- it looks like some of the lobster fossils i’ve seen on here, but i just wanna be completely sure. It’s 3 centimeters long, half a centimeter wide. Here are the photos i took (sorry the lighting sucks, i’m trying to heal some pretty bad sunburns) image 1 (top) Image 2 (bottom) image 3: right image 4: left image 5: front image 6: back

I’m very sorry for posting so much- i got bored yesterday so i put on my boots and went down to the creek not too far from my house! This specimen in particular caught my eye- while it’s probably just an eroded rock or something, i’d still like to see what yall think!

This looks an awful lot like a worn jellyfish fossil, however there are some stones with odd name that look similar, maybe trace fossil can't remember. The other side doesn't look like anything. North Texas Cretateous. Help!

I overlooked this yesterday thinking it was some shell mix, but after getting it wet some strange things stood out. Included pics both wet & dry and yes some are blurry but show shapes. I put a drawing of what is down that crevice since it would be impossible to get picture of it. There are no shells far as I can tell. Wish I knew how to clean & prep it! Almost forgot, creek this was found in borders Eagle Ford & recent deposits, north Texas.
