For Christmas, I'd gotten a box of matrix from the Lance formation. I have some fossils that I am not sure what they are and would like to get your opinions. All of these fossils are from the Lance formation of Weston Co. WY. The first one is I think a theropod ungual, missing both the distal and proximal ends. Here are the pictures. The second one I'm pretty sure is a partial Edmontosaurus metacarpal. The The third one might be a ornithischian ungual. And here is the final one, I think that it might be a jaw section.

I posted this originally in the “questions and answers” forum, but I think it fits better under fossil hunting trips since it discusses finds: What are some of the best fossil bones people have dug out of the Aurora Fossil Museum Pungo River dig pits? The actual reject pile DIG PITS, not the mine before it closed. There are some nice fossils to be found there, but I’m curious if anyone has ever managed to find for example a complete rib, or a vert. with all its processes, or a full-on cetacean jaw bone, or by some miracle an entire skull. Most fossils from the pits are somewhat beat up at a minimum, just curious what the ceiling for quality is from the dig pits for bones.

Hey guys, I have a special creek site close to me in South Florida. it yields marine fossils of every kind and even some artifacts. I have found many pieces of dugong bone with a strange circular indentation, and I’m really hoping someone can help me out with determining what causes this? I have found fossils of a huge variety of Pliocene/Miocene marine animals, and dugong bones are the only bones with such markings. There is a raised center and an almost perfect circular depression around it.

Today @PFOOLEY and I went behind the scenes at the NMMNH&S. Thanks to Dr. Spencer G. Lucas for letting us in and showing us some amazing specimens. We started with some heteromorphs... ....donated from Utah There were other ammonites... We then ventured into the other room full of goodies... ...this Parasaurolophus.. See it? Some plant fossils... I am super thrilled to have had this opportunity to see these amazing specimens up close. I wish I could share all of the photos but there are a lot! I hope you enjoy... Dr. Lucas was also kind enough to give me these bulletins...I have a lot of reading to do! Salúd!

Hello everybody, I'm sorry for making thread about ID mixed fossil types,but I didn't want to open multiple threads for such a small specimens as they aren't something ''special'',but small specimens that I would like to properly ID. They were bought from one small fossil shop that sells fossils,meteorites,amber,dinosaur teeth and those kind of things. They are fairly small shop,but they have nice collection of small affordable fossils for sale. I bought them years ago and I always wanted to get proper ID of them,but my camera wasn't good at the time and I always had more ''important'' things to do. Today I finally got time and I took photos,but unfortunately I forgot where did some of those fossils came from as too much time has passed. I remember some of them,but not all. All of those fossils were cheap. Fossils are placed near metric ruler for size reference and are measured in centimeters. First fossil is Spinosaurus Aegypticus (Cretaceous Period 90 MYO) found in Kem-Kem basin Taouz Morocco It is 4cm long. I would like to know is it possible that tooth from Spinosaurus is sold that cheap and is authentic as well since it's rare animal? I know they had lot of teeth during their life that were constantly replaced by new ones as the animal ate/broke them,but I still having hard time to believe that authentic dinosaur tooth is sold for so little. Second fossil is trilobite that is from Cambrian period if I remember correctly.I forgot location where it came from unfortunately. It's only one centimeter long and I'm not sure if it's authentic or not because bottom of it look somewhat weird (at least to me). I uploaded 3 pictures of it. Third fossil is Neuropteris seed fern Carboniferous period (320 MYO) from Crock Hey pit-Wigan Lancashire UK I uploaded 3 pictures of it and I would like to know do you think it's genuine? Next two fossils are supposed to belong to Tyrannosaurus Rex,but they are so small it's impossible to tell from what dinosaur they came from,if they even belonged to a dinosaur. It's stated that they are from Tyrannosaurus Rex Cretaceous period (65 MYO) Hell Creek formation Northwest South Dakota-USA As far as I can tell (and I don't even belong to newbie amateur class) they seems to have honeycomb like structure that could be where the blood vessels were once the animal was alive. If it's a dinosaur I presume it would belong to some Theropod because of that honeycomb like structure,but that just my humble inexperienced opinion. I uploaded 5 pictures of those two fragments and I would very much like to know did it belong to some Theropod or at least a dinosaur and do they look like they really came from Hell Creek formation judging by color and things like that? Note: 4th T-Rex fragment picture have one side completely yellow that is totally different from rest of the specimen.Do you perhaps know what that is? And lastly,last two bone fragments are stated as ''Triceratops'' bone fragments,but I'm aware that's impossible to tell just like ''T-Rex'' fragment from above because they are simply too small. However,I would like your opinion about them as well. Do they look like fragments that belonged to dinosaur at least? They came from either Montana or North Dakota and I think they are too from Hell Creek formation like ''T-Rex'' fragments,but I'm not 100% sure,more like 90%. They are of course 65 MYO,at least that's what seller stated. I uploaded 7 pictures of those 2 fragments. Once again,I want to apologize for multiple different specimens in one thread,but I think you'll agree that this is better than opening 5-6 threads for such a small specimens. Lastly,I want to thank you for taking time to read this and I hope you can tell me are all those fossils genuine and if those 4 fragments came from some dinosaur if you can get any info from small fragments like those of course. If you have any questions that could help you get better ID,feel free to ask them. Thanks!

Can anyone identify any of these bones found by my 7 year old at Wapping pls? We went to look for the gallows at the Prospect of Whitby pub and literally stumbled upon these. She’s very excited to find out what they belonged to and has taken some to school today! We are thinking cow or horse due to sheer size and weight. Thank you ..

Really odd shape from Calvert formation of Virginia/Maryland. Any idea what kind of bone or what it’s from?

I found this at westmoreland in Virginia. Does anyone know what kind of bone this is or what it could have come from?

I am doing some research on dromaeosaur bones, and I only found limited data and pictures on the web. I am particularly looking for caudal vertebrae and ribs pictures and structures. So I make an attempt towards TFF members knowledge and data !

Hello, Newbie here. These are my 9 year olds “dino rocks” as she calls them. All I know is my elderly neighbor gave them to her as his grandkids were grown up now. He had no back story on them at all. He said they were eggs and look really cool. The larger one is 11 lbs! Please any help for my daughter would be great. This is our first post so go easy on us. Lol thank you. ( I did read some of the “newbie” post.)

I submit 3 bones today: Age: campanian Location: south of france Deposit: continental / river Bone 1 : 10cm wide, thickness 3 mm. I dont think it is a shell Bone 2: 6cm long, view from the top and from the side Bone 3. 21 cm long. 1cm thick on one side. 1mm on the other. Convex.

Hi all, While I'm aware that current Cretaceous exposures in Britain are largely restricted to the south and east coasts of the islands (see geological map below; source), significant marine deposition is said to have taken place across much of Great Britain from the Aptian onward (source). As such - and especially considering the richness of the record of the marine ecosystem during the Jurassic- one would expect an abundance of marine reptile remains to be known from British Late Cretaceous sediments as well, the epitome of which, of course, would be the mosasaurs. However, whereas finds of remains of ichthyosaurs and pliosaurs have been reported (see, for instance, Fischer et al. 2014 or Madzia 2016) - albeit from somewhat older strata than from which one might expect mosasaur remains to show up - very little information actually seems to be available as concerns this highly diverse group of marine squamates. When browsing the literature, for example, I've only found limited references to mosasaurs in Britain, most notably in Benton and Spencer's (1995) "Fossil Reptiles of Great Britain", in which the authors (p. 221) observe that Some further mentions of mosasaurs are made in this work on pages 264-265, which include lists of marine reptile finds at various locations across the country, as well as page 270, which describes St. James's Pit in Norwich, Norfolk, purportedly "Britain's best mosasaur locality" (ibid.). The pages have been reproduced below for ease of reference: Some material is also illustrated and described by Milner in "Fossils of the Chalk, second edition" (Smith and Batten, eds., 2002), but again minimally so: Plate 64 3) Leiodon anceps, Campanian, Norwich, Norfolk; 4) Clidastes sp., ?Upper Turonian, Dorking, Surrey; 5, plioplatecarpinae incertae sedis, Upper Chalk, Sussex Plate 65 1) Clidastes sp., Upper Chalk, Sussex; 5) cf. Tylosaurus, Santonian, Forness Point, east of Margate, Kent Outside of that, over the past couple of years I've only bumped into some loose specimens here and there being offered at auction sites, such as the below batch of alleged mosasaur teeth from Worcestershire, purportedly once part of the prominent Gregory, Bottley and Lloyd collection (at the resolution provided and in their state of preservation it's hard to make out whether they are indeed mosasaurian, however); or the mosasaur lumbar vertebra of unknown origin. It was actually these specimens that first attracted my attention to the existence of British mosasaurs, since so little has been reported on them elsewhere: an internet search doesn't result in anything fruitful, for example, nor have I come across any mosasaur material listed in museum collections. I would therefore be very interested in hearing what you all make of the above specimens, as well as the apparent paucity of British mosasaur material either in museums or published literature. Is this just the outcome of a collection/research bias, lack of suitable accessible exposures, or could there be another reason... @Praefectus @JohnJ @caterpillar @Welsh Wizard @paulgdls @DE&i and others

Here is an interesting what appears to be a huge foot... this rock is approximately 18in in length... definitely not normal from our perspective in today's time... just curious about your thoughts...

I am very curious what exactly this is....can anyone help me identify this fossil...was discovered in california.

On a couple of recent trips to the Whitby coast my daughter and I collected quite a few chunks of a large septarian nodule (or perhaps more than one nodule, though everything was collected in a small area) containing bones. Most of the pieces we found just contain ribs, but one piece contains a couple of larger bones. I’ve had a go at prepping the two best bits, is anyone able to suggest what the bones might have belonged to? Thanks for looking FullSizeRender.mov

Please help me figure out what this is

This was recovered near a gold mine in western Montana. I have absolutely no idea what it is. any help would be appreciated. Thanks!

I'm trying to identify this fish skeleton. It's clearly some sort of RAM feeder, but beyond that I've yet to find something with the single dorsal fin. Can anyone help me out with this? Sorry about the small picture, I cannot make it bigger for some reason.

Hello, We found this item in a crop field when out on a hike and would greatly appreciate any help to identify whether it is a bone or something else. It looks like the end of a bone, the ball bit that goes into the joint or maybe not? We first thought it was human or mammal but then saw it was fossilized rock with signs of wear and tear and maybe teeth marks. Also we can see what looks like fossilized pinkish marrow in the middle of the bone that is more prominent than the picture shows (sorry) with little air pockets. There was also lots of rocks and interesting bits and pieces in the soil. Thanks in advance for all help given, Al Location of find - Leicestershire County, East Midlands, UK

I went to peace river a couple years ago one time. Went to one park - was pretty much over picked with craters everywhere. Found those in one illegal dug banks pit. They're the most easily identified pieces I could find - rest was just bone pieces, ark shell molds, and pieces of shells. Second picture is when I went to key west one time there was calcite pieces spread all over the beach - not too far from the fort. Two pieces of calcite had strong resembles to teeth. Third picture is the best I could find from the pieces of bones that I had found at peace river.

Hello guys , I found some bones in big brook (Cretaceous fossiles), nj and I don't know if they are modern or ice age. I also added another strange fossil I found but can't id

I found this fossil at Caspersen Beach Florida, while snorkeling please help me identify it, ill go crazy if i don't find out what it is.

Hello! I've always loved digging up whatever I could find. Sis and I had a shed of bones growing up, and I have an opposum being cleaned in the backyard. I also got so excited when I'd find shells in our Kansas yard. Now I live WPB and can get all the shells I want! Great to meet all of you!

Found in Manistee County Michigan. Can anyone help to identify?

I am unable to identify these pieces from my grandad's collection. He is now unable to clearly see and so sadly couldn't identify it. It must be something, he was a zoologist and the shale meant enough to have a crack repaired. Parts look like bones to me. I'd love to get these identified so I can prep them, making them clearer so he can see them clearer again.
