  1. Kinda late to start up a long post about my trip today...so I'll just say it started like this . A bit more snow that expected. Crossing the summit @ 7500 feet above sea level. Back in January there was much LESS snow than this. I was hoping the downhill side was nice and dry. It was...turned out to a beautiful day with 63 F degrees before a front blew in. And the trip ended like this...the juvenile raptor sculpture is about a meter tall and the adult is about 2 meters. Looks to be made of CNC cut 3/16ths or 1/4 inch mild steel. Probably waterjet cut. Pretty cool. The toe claw suggests it's a Utahraptor, but with a T-Rex head? Stay tuned...I'll fill in the trip tomorrow.

    Bone fragments

    Hi, these are some of the bone fragments I found recently in Monmouth County, NJ (Big Brook and Ramanessin Brook). I know how hard it is to assign bone fragments to any species but some of these have some unique features that maybe someone with more knowledge than me has something to say. Number 1 (from left to right) is bent, maybe some part of a jaw? Number 2 is quite curious, very smooth at the top with a bulge and a triangular indent on one side. Piece of some turtle armor perhaps? Number 3 is flat and smooth on one side with a line running through it. Maybe a turtle also? Number 4 is super thick almost like a finger bone. But also smooth on one end with a line running through. The liner is slightly more irregular than that of Number 2. Number 5 is a lot bigger with an indent on one edge. But probably also quite stream-worn.

    Supposedly Spinosaur bones from Morocco

    Kem kem bones, supposedly Spinosaur Hello all, i recently got two bones that come from Morrocco, kem kem formation, suposedly belonging to a Spinosaur. They seem quite peculiar and could actually come from anything. Attached are some photo’s, does anyone have an idea what it could be?

    Thililua longicollis tooth?

    Tooth measures .83 inches and wasfound in Asfla, Goulmima, Morocco at the Akrobou Formation. From what I’ve read this is either Thililua or Manemergus Anguirostris and the seller wasn’t 100% sure.

    Unidentified Fish from Lebanon

    Trying to ID this fish from the Sannine in Lebanon and having a bit of trouble. About 13cms in length. The dorsal fin seems like a good hint, but haven't found a match for it yet. Anyone got any ideas?

    Texas fossil ID

    A friend and I went fossil hunting in Johnson County, Texas in a few rivers. I'm not sure which formation these were in but my friend said this is dated to the Cretaceous period but he wasn't sure what part. He wasn't too familiar with what species are fossilized here. Is anyone familiar with the fossils in this area? 1-4 (left to right). I'm unsure about these ones. I think they're just interesting rocks but there were a lot of these in the river. I suspect the far right is a fishing lure of some kind too. 5. This was a pretty neat bivalve that was found away from the river. I'm not super familiar with bivalve anatomy but what are those 2 bumps on one of the sides? 6. I'm fairly sure is an ammonite fragment. Are those 3 rows of bumps identifiable to a genus or is it better to leave it as just as ammonite? 7. Not sure if this is turrilites. Is it possible to remove it from the matrix or is it better to leave it like that? 8-14. Assorted shells for the most part. I found 3 complete bivalves which was exciting, one with the pattern still intact! The last one is really interesting to me though. My friend suggest maybe it was a fish vertebra but he's not 100% sure. I'll be posting their pictures from left to right. 8. 9. 10. 11. 12. 13. 14. 15. Tiny clam? 16. One of my favorite finds even though it's so weathered down. Not sure if it's an ammonite or nautiloid though 17. An inoceramid? It looks like the pattern wraps around the rock so I'm not sure if that's how thick they are or it's something else Thank you all for your time!
  8. Hi TFF, As the warm weather collecting season winds down, I found some time recently to snap some photos of finds from Ramanessin brook over the past few years that still give me pause, would appreciate help nailing down some IDs! Photos below, most edited to be brighter and higher contrast I believe this is a shark coprolite based on the "acorn" shape I've debated on this being plesiosaur or crocodile for a while but do believe it being plesiosaur given pronounced striations, lack of cutting edge and the conical U shaped root present in the second photo In contrast, I believe this to be crocodile This tooth in particular has stumped me for a while now, I have not found another like it but believe it to be a sand tiger shark (Carcharias holmdelensis) This I believe to be pathological of some sort These two, I'm thinking Enchodus Finally, the mysteries - I have no clue what these could be! Mystery 1 Mystery 2 Thanks!
  9. Cretaceous Porcelain Crab Petrolisthes landsendi new species Late Cretaceous (Comox/Haslam Formation) Saanich Peninsula, Vancouver Island, British Columbia, Canada Donated to the Royal British Columbia Museum, Victoria, BC https://www.researchgate.net/publication/347129633_A_new_species_of_Petrolisthes_STIMPSON_1858_Anomura_Porcellanidae_from_the_Upper_Cretaceous_upper_Santonian_of_Vancouver_Island_Canada It was determined that this fossil specimen collected by me and formerly residing in my collection was potentially a new species. After sending the specimen to Torrey Nyborg for examination, it was confirmed to be a new species of Porcelain crab from the late Cretaceous of Southern Vancouver Island. This new species was determined to be the "oldest species of Petrolisthes Stimpson, 1858 and is the first species from the northeastern Pacific".

    Is this a vertebra or something else?

    Found what might be a vertebra yesterday- let me know what yall think with these photos! It looks like it’s about 2 and a half inches tall, or about 6.35 centimeters. It looks like it’s 2.56 centimeters long. Both are just my closest estimates, so take them with a grain of salt-

    Mosasaurs #5

    Hi guys got a few more for idenitification thanks for your help 1. this was broken in shipment and is completely hollow even the root is this normal? The rounded cross section makes me think T.atrox 2. slightly more compressed, eramiasaurus? 3. gavialiminus? 4. another gavialiminus, any idea why both of these are so compressed? Preservation?

    Very unusual microfossils

    Hello everyone, Following the previous posts about other fossils found in the same marine upper cretaceous sediment (campanian), here are two very intriguing finds I could not classify at all. Does anybody know what they may represent?
  13. Looks like a fossil vertebra? Any one know who it goes to etc. first dino or shark cartilage/bone if so!!!!! found in Arlington Texas at construction site in layer with gypsum and few Cretaceous aquatic shell fossils and one shark tooth. It is pretty brittle etc. will epoxy soon after positive id. I’ll post a pic of shark tooth also.

    Can’t figure this one out

    I found this in a creek near Glen Rose TX. It’s supposedly from the Glen Rose Formation and would be considered the Cretaceous period. If anyone one knows what it is that would be nice to put a name to it. It is 5 cm length and 6 cm height wise. Thanks!
  15. Hi! Please help me ID these fossils. I believe the first one is crocodile tooth but not sure of the other 3. Thanks!!

    Various fossils/possible fossils

    Various fossils/possibly contain fossils. From the Coleraine formation of northern Minnesota, mostly ironstone, I think, but one is in mudstone.
  17. Any thoughts appreciated. Can't find anything that looks like this found in Big Brook NJ. End seems too round to be in pincher? I know this is a stretch prob but the only thing I found remotely like it online was a pic of a baby Mosasaur jaw fragment. Thanks!!
  18. #1. Not sure age #2. Not sure age #3. Pliocene/miocene #4. Pliocene/miocene #5. Not sure age #6. Not sure age #7. Not sure age #8. I believe Cretaceous?

    Texas Shark Teeth

    Can anyone help me ID these two shark teeth, they are from Texas so that might help limit options.

  21. Recently visited the Green Mill Run area in NC and found some fossils that thought would peak some interest but need the help of identification. I know the site can have a bit Cretaceous but also Eocene and Pliocene, so it can make it harder to identify things. The first one I assume might be crocodylian or maybe turtle, not sure. Those thick grooves make me think maybe crocodylian. The second seems like, from looking at the root base, a possible theropod tooth? I thought maybe claw of a turtle, but seeing that thick base makes me think otherwise. Lastly found what I think is some claw. Of what? I don't know. Dromeaosaur? The tip is clearly broken off, but the grooves on the underside are clearly noticeable. Any insight would be of great help. Thanks!

    4 Mosasaur Verts in a Day! Austin TX

    With the end of the semester approaching, school has picked up and I have been too busy to embark on many adventures. When my schedule finally cleared up one afternoon following a brief rain in Austin, I jumped at the opportunity to do a bit of exploring. One of my goals right now is to check out new parts of the creek I hunt on. Scanning through my list of potential spots, I decided to try and be the first one out to a very promising location. Like my previous hunts, this place ran through the Ozan formation, so my expectations were set on some nice Cretaceous specimens as well as the usual native artifacts that Central Texas is so famous for. After I parked and carefully scaled my way down to the water's edge, I was immediately met with several pairs of shoes and jackets. Thinking I had been beaten to the punch, I decided I might as well head down the stream and meet whoever it was to discuss the location and fossils in general. Thankfully, the trip was saved when they turned out to be a kind group of fishermen. After a brief chat, I carried on to get the hunt started. The mud was an absolute nightmare. I had never been up to my knees in it until then. Somehow, I managed to trudge my way through without getting one of my water shoes sucked away into a different dimension. When I finally reached the first gravel bar, I was instantly rewarded with the nicest Ptychodus tooth (E) I have found yet. Scattered around the bar were tons of flakes and a couple of larger worked pieces (G, I) that were unfamiliar to me. Before moving on, I also stumbled upon what would've been the largest point I'd ever found (H). Unfortunately, it was pretty banged up. The previous rain wasn't that big in terms of flooding, so I spent the most time scouring the gravel still under water as I reasoned that the stuff on dry land was less likely to have been moved around in the storm. It was during this moment that I found my first mosasaur vertebra of the day (A). This one was exciting to me as I personally thought it very much resembled the verts that famously come out of the NSR's Ozan formation. Within a couple feet of it I found another half piece of mosasaur vertebra (B). With the close association of these two bones, I went into a bit of a frenzy. Nothing else came up, but I knew that there was a massive exposure just up ahead so I hurried on. Along the way I ran into a fragment of the smallest point I've come across (F). At its size, I wonder if the original piece would've been a true arrowhead. Once I reached the main exposure, I immediately got to probing around. I came across two more pieces of bone that I believe are both belonging to mosasaurs (C, D). They have bony structures, but they are also pretty beat up and may have come from a different formation in comparison to the other two verts I collected. With the day winding down I picked up a nice big Exogyra ponderosa for my dad's friend as well as a couple of preforms. I tried to look around in the exposure for any hints of mosasaur, but that shale is extremely difficult to get through. All in all, it was a great success. I think I've found my new go-to spot! With the addition of potentially 4 new mosasaur verts, that's a 400% increase in my total mosi collection! P.S. Does anyone else get "Tetris Syndrome" after scanning gravel bars for way too long? For hours after the trip, I literally could not stop seeing gravel and chert flakes every time I closed my eyes. An overview of the finds: Closeups for ID: A: First mosasaur vert of the day. To me, it strongly resembles those found in the NSR's Ozan formation. This one was covered in a clay-like matrix. B: The second vert of the day. Seems to be broken in half and from the same formation as A. Appears to have pyritization on some parts of it. C: Third vert which I believe is mosasaur. This one is beat up and seems to be of differing material from A and B. Could it be from the Austin Chalk which is present farther up the creek? D: The last "vert" of the day. This one I am least confident about. It appears to have a bony texture, but is very worn and has a confusing shape. It seems closer to C than A or B, but it also feels very distinct in it of itself. What do you guys think? I suppose it could be something else entirely! E: A nicely preserved Ptychodus tooth. I'm thinking anonymous or mammillaris, but my ID skills are pretty lackluster. F: "True" arrowhead fragment? G: Strange artifact. The angle seems too wide to be a point. I think it's too thin to be an adze. Obviously missing a huge chunk from that fresh curved break. What do you guys think? H: Fragment of a large point I: Another strange fragment. I think it may be an adze since it's a bit more robust. Fresh break on one edge. Let me know if you want any more close-ups. Thanks for reading!

    Cretaceous Print?

    Hey y’all! Can anyone help me ID this print? I’m a marine reptile researcher so I’m at the end of my understanding of prints for this. It was found in Bell County, Texas. Thanks so much!

    Austin Chalk Mosasaur Fossil ??

    I found this rock in Austin, TX in Waller Creek next to an exposed outcrop of the Maastrichtian (Late Cretaceous) Austin Chalk. I’m wondering if it’s a mosasaur vertebra or humerus? Several mosasaurs have been found in creeks nearby, and the wavy pattern in the rock reminds me of fossilized bone. I’ve included three photos of the rock that I found in Austin, and a photo from Otero et al. (2016) of a Maastrichtian mosasaur right humerus (scale bar = 50 mm) that looks similar.
