Hi everyone! I could really use some help identifying this one. I found it at Post Oak Creek. I included a bunch of pictures that I labeled so you all can know what I'm talking about. The microscope shots have a red scale bar that is 1 mm. Here's what I know it's Cretaceous 94-90 million years old from the Eagle Ford Group. the bone surface is mostly weathered but still in it's original shape. except for some major weathering on the back of the left side. It came from a large vertebrate. The bottom is flat, the back is concave, it slopes forward to a blunt point in the front, It appears to be mostly symmetrical with the line of symmetry going front to back. It looks like a distal phalange (finger tip bone) to me, but neither Mosasaurs or Plesiosaurs have a bone that looks like that to my knowledge. It honestly looks like the distal phalange of a terrestrial vertebrate to me, but, well, yeah I need another perspective before I go that route. Hey I can dream right?

Hey y'all Here's a bone fragment that I think might actually be identifiable from a creek around the austin area. Ozan formation. My thought is it may be fish, but I can only really base that on size. I found some other pieces after the storm recently as well, but all the others are probably just "chunkasaurus". thanks for any input, I'd really appreciate it

Eagle Ford sandstone, found a cool trace fossil and curious what made it. Could only find one somewhat distinguishable thing and really can't tell what it is other than looks like shell. Lots of burrows and maybe worm? Found several little circles with dot in the middle but hard to get all images. The trace looks like a sperm best way to describe it.

Hi everyone, I just ordered this beautiful vertebra found in the Niobrara Chalk of Kansas (Cretaceous, 87 - 82 mya) for quite a bargain. Unfortunalty I don't have any precise location as where it was found, for that I am going to contact the seller. The vertebra was listed as being Mosasaur which it could very well be, but since it is a little bit distorted I am not quite sure, especially since many other critters can be found in the Niobrara Chalk. So I was hoping on the expertise of some of our members here who have more knowledge of Cretaceous verts and of Kansas fossils. @KansasFossilHunter @Troodon @LordTrilobite @pachy-pleuro-whatnot-odon @The Amateur Paleontologist you guys might be able to shed some more light on the piece? Thank you in advance! Topic might be more usefull with some pics, so here they are.

Hello Everyone I recently came across three interesting bone fragments while hiking near the Red Deer River North of Drumheller ( Alberta, Canada). The one bone fragment has a perfectly round symmetrical hole right through it, & the second & third fragment appears to have little pock marks or indentations on it (reminds me a bit of the whisker pocks a dog has on its face) . Anyways I am just a hobbyist however the fragments with the pocked marks I'm going to guess is part of the jaw or maybe somewhere near the mouth? Any help to help ID or any additional information of any kind would be greatly appreciated. Thank you all in advance! Have great weekend.

Hi everyone! I went to Post Oak Creek, Texas a few weeks ago and got a decent haul. Including three teeth that I think are from some rare species that I wanted to confirm my id on. I think the first two are Cretoxyrhina mantelii and the third is Protolamna. I'm particularly unsure with the second one since it seems to have a slight nutrient groove. The first one also has damage where there would have been cusps so I'm not sure if it's a different Cretoxyrhina species or a different genus entirely. I'm fairly certain the creek is Atco formation. I know it's either Turonian or Coniacian

I dug these two cephalopods a couple months apart at the same place within the Cretaceous of North Texas and did not know if they were an ammonite or nautilus species. I do think they are part of the same genus though. After more research I thought it could be an oxytropidoceras species. Still not sure what genus or species it is but I'm leaning towards a type of ammonite. The place I found these ammonites at, usually has Mariella ammonites and no other type of ammonite. But these two are the only ammonites from the area I've seen besides Mariella species. Any help would be appreciated.

Hello everyone, I hope it going well for you! I recently ventured out into the Cretaceous of New Jersey and have come across a fossil that has me stumped. I went along with my friends Roy (not on forum) and @The Jersey Devil and the day was somewhat slow. Other than this interesting find, I think I may have found a partially hadrosaur tooth, but I need to take some better photos of it. The tooth is quite worn. I have included my other finds from the somewhat short trip. My guess for the fossil is fish spine. I hope you enjoy. @non-remanié THE MYSTERY FOSSIL GENERAL FINDS

Hi all My kids and I found this piece at the NSR and saw that there were multiple bone fragments in it. Do you all think that there is a fish jaw in the lower right portion of the specimen? If so, can anyone tell from which type of fish it is? Thanks in advance! Bret

I have several peices of Cretaceous Lens from Eagle Ford and decided to investigate it further, dissolving in vinegar and picking at it and so far came up with these. The one in the matrix looks like tooth or claw maybe, the base of it turns to white but it's eaten away and hard to see in picture. The other things are different, there are quite a few I can see in the big peices some are so small I can't photograph them. Urchin spines are the closest things I've seen to these but really don't know. The pen tip is next to objects for size comparison.

Hello, I was going through my “toss” pile today from my local haunt and I noticed something black and shiny peeking out from one. So, I decided to (for the first time ever) break a find open. I was glad I did because I was pleased to find a tooth! No idea what it is, since it is still very much still in the material I found it in and I can’t match it to something I’ve found before. This is new territory for me and so I’m looking for advice. Should I leave it as is or try to remove it?

Hello! Having discovered some new rudist occurrences in the lower part of the upper Santonian - lower Campanian clastic-marine Afling-formation at Römaskogel hill near Kainach, western Styria, Austria, about 6 weeks ago. Here I would like to present a very specific visit to one of these sites at 05/15/2021. It was aimed to recover some more parts of already known rudists from the outcrop at site #30. Here we go! Approaching Römaskogel, the hill in the middle. Its 1006 m high, the snowy mountain in the background is the Gleinalpe mountain, nearly 2000 m high: Already near Römaskogel hill, again the hill in the middle. These meadows are much steeper than they appear in the pic: Location of the rudist outcrop along a forest road: Rudist outcrop, scale is 1x1 m. The rudist-bearing zone is about 80 cm thick and tips gently towards south to southeast. Individual conglomeratic rudist-bearing beds are separated by layers of siltstone. The whole extensions of the rudist-bearing zone seems to be at least about 300 m, with about 5 outcrops and indications known until now. This is the best outcrop discovered so far. Right part of the rudist outcrop. At the lower end of the scale, the next pic. The digging spot of this day is to the left of the pen: Rudists ("Vaccinites Rö1") in conglomerate in the outcrop, diameter is about 5 cm: The digging site as left at 05/06/2021 and found again a week later at 05/15/2021. I had already recovered two parts of #4901 and one part of #4910. The soft siltstone in the footwall of the rudist bed clearly facilitated the recovery of the remaining parts from the relatively hard conglomerate. The pen is 13.7 cm long: Intermediate stage of recovery. The rudists are orientated parallel to the bedding plane. They are flattened, the two big ones lying with the flat side on the bedding plane. The smaller one is orientated "on edge" to the bedding plane: Here is a primitive, highly schematic and out-of-scale sketch of the situation. #4901 and #4910 are also oriented antiparallel: Dig site after removing all the rudists. #4901 yielded two more fragment (total of 4), with the very last tip still remaining in the outcrop. #4910 yielded also two more fragments (total of 3, completely recovered). #4914 recovered in two fragments: Right part of the rudist outcrop after recovery of these three rudists. Notice the difference to the start of the recovery : Here is the complete specimen #4910. It consists of 4 fragments, that were already naturally broken. Uppermost part was found 05/01/2021, next part was found 05/08/2021, lower most parts are from 05/15/2021. The rudist is strongly flattened (about 1:2), as most of the specimens from this bed, and about 21 cm long. I don´t know the species yet, working name is "Vaccinites Rö2". (Remember, nothing was known in that area until about 6 weeks ago.) The shell has a flame-like structure, which can be nicely seen in the naturally weathered transverse section. These structure corresponds to the fine longitudinal striation of the shell. Otherwise, the rudist is smooth without any ribs. In the cross section, the P-pillars are barely visible to the right, the L-pillar is not visible: Not much time was put into this recovery, most of the day was spent prospecting an area nearby. "Discovered" a freshly widened forest road (actually as wide as a good highway!) which perfectly exposes the mostly alluvial and reddish Geistthal-formation and the following clastic-marine Afling-formation for some 100 m thickness. Not much was found, but its a very, very impressive section. Here is my prospecting area (Römaskogel is in the lower left corner) and route (in blue) of that day. Red R indicate the last (highest) reddish beds: Still a lot to walk and observe during my next trip, especially to the east of the already explored area.... You never know what you will find. For example, #45 and #46 are small Trochactaeon indications. But these will be followed up next spring, when the green has gone again. Or not at all . I only made one pic during prospecting, that of a thin (1-2 cm) seam of subbituminous coal withing silt-claystone, located between conglomerate beds (#47). Such occurrences are well-known in that area: So, that was quite a typical day in the field for me: Some collecting at known sites, but more prospecting for new sites! Thanks for looking and your interest! Franz Bernhard

Hi there, Found this little one the other day on the cretaceous formation (upper I believe) and was curious about the species. Can someone identify? Thanks

Please could anyone help me with the identification of these fossils. I have very limited knowledge so appreciate any comments. All fossils were found in Thumamah Park near Riyadh in central Saudi Arabia and all were collected loose from the ground. The age of the formation here is Cretaceous according to the geological data I can find. The bottom two photos are two sides of the same fossil which looks to me like an oyster of some sort (but could be totally wrong). Thanks in advance for your suggestions.

Hi all, I picked up a lot of partial ammonites and ammonite imprints on my latest fossil hunting trip. I was wondering if anyone may have an idea as to which types of ammonites I've come across. They come from the Paja formation in Colombia which is part of the Cretaceous. Thanks in advance
