These bone fragments came from Hell Creek formation in Montana. They have an interesting curved edge on all of them. There are 3 smaller ones grouped together and one larger one. The scale is in inches on these. Any ideas what they may be (rib?)?

I have two of what I think may be pieces of skull bone. They come from Hell Creek formation in Montana. Am I right? If so, any idea what the skull is from? The scale is mm. I also have some bone chunks from the same place, but will do it in another post due to file size.

A month or so ago a French friend came over for a fossil hunting vacation. With my new wife's blessing (and his wife's as well), we spent 8 nearly solid days of fossiling here in Wyoming before the snow flew.... literally. I spent a good chunk of time since then preparing some of my finds and some time writing up our adventure. It is very photo-heavy, so I had to break it down to three chapters. The first is posted here and I hope the others will be posted in replies. Enjoy. Outing w caterpillar Ch 1.pdf

I found this thing together with many pieces of Cretaceous petrified wood. I take it to my home, because of its interesting form. Niw i am trying to know what is it, but can not find any similar pictures. What it could be? I found it in Kazakhstan. Thank you!

This tooth, "pseudohypolophus" has yet to be assigned to a family. It is believed to be an extinct Rajiforme, specifically a guitarfish. Tooth crowns are very common in Black Creek sands, but are very rarely found with the roots.

Dubious Kem Kem 'Spinosaurus' Tooth
TXV24 posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hi, I've noticed a lot of talk about the different issues with theropod teeth that originate from the Kem Kem beds on this board, and it reminded me that I had a 'Spinosaurus' tooth in my collection. I bought it when I was a kid, and obviously didn't question it's legitimacy or ID in any way. But now that I'm older and have a lot more experience I noticed some features of the tooth that I find slightly dubious. Firstly is the size, it's small, only around 3cm which doesn't compare to some of the enormous teeth in the dentition of Spinosaurus that I've seen. Secondly is the presence of sandy matrix material around the base of the crown which as I've read on here can indicate restoration, and to me looks quite strange. I was wondering if anyone could help confirm if the tooth does appear to be from a Spinosaurid and whether or not it has been restored/composited in anyway. Thanks, Theo

I found this little guy going through some matrix from the Aguja formation, Brewster county, in west Texas. It is late Cretaceous. I can't tell if it is a tooth (as from a multituberculate mammal), a jaw section, or just a suggestively shaped rock. What do you think? I have attached the bottom, side, and top views. The hash marks are 1mm. Thanks for any help.

Curious to see if anyone can ID this bone fragment? Thanks! Bison? Deer? It was found in the Fredericksburg / Eagle Ford groups, thereabouts.

Took an hour for a walk in a creek not far from where I live. We have had rains earlier this week so thought I would take a look at what washed out. This creek does not produce a ton but always gives up something if you look hard enough. Found a jaw section, possibly small mosasaur and a partial turtle scute. Wish I had more time to get out there but very pleased to have found this. And the turtle...

found some nice stuff today,,,,along with the verts and teeth a old glass insulator and not sure if I have a jaw piece of something or its nothing any help with last 3 pics....thanks

Greetings! I found what I believe to be a tooth in a Cretaceous tributary of Big Brook in Monmouth County NJ and need help with identifification. It is slightly concave at the root and has a hollow section at the tip and one cutting edge, and has an oval cross section. This spot has yielded a good amount of both terrestrial and marine Cretaceous specimens. It doesn’t seem to match the usual suspects from this area so I would appreciate any help. Thanks! -Frank Additional pictures.

In going through some matrix from the Lance Formation, Late Maastrichtian, Wyoming, which shares much fauna with the Hell Creek formation, I have found even more interesting things since my last posting on this area. 1. The first I believe is a theropod, similar to the one in my previous posting, although slightly larger. 2. Is this (unknown 11) also a theropod tooth, or maybe crocodillian? 3. Is unknown 10 a pycnodont fish tooth? 4. Unknown looks like what has been identified as a ceratopsian "spitter" tooth in a previous posting, but this seems awfully small. 5. I have no idea as to what unknown 9 is. It looks like a tiny jaw with teeth, but seems to be closed off on both ends. I tried to clean it more, but was afraid of breaking it - it's only 2mm. 6. Unknown 6 looks like some tiny amphibian (maybe Newts) teeth that I have seen from the Permian, but not sure. 7. Unknown 7 also reminds me of ceratopsian teeth, but once again, this is really small and flatter. The hash marks are 1mm. Thanks for any help.

Hello all, I usually post up photos of shark teeth and other misc things, but this time I'll only ask for help with the more unusual fossils I've come across at big brook NJ. First photo I thought enchodus teeth. Second xiphactinus or enchodus again. third and fourth photo (same fossil) maybe jaw or beaver tooth. fifth photo no clue but maybe bone? sixth photo looks like fossil cocoa pebbles.. Last three photos are of the most interesting find, no idea but was hoping it would be a chunk of tooth. Thank you for any help in IDing these.

First, I am clueless as to what this is. I am guessing whale because the vertebral body is concave on one end and convex on the other. It is pure stone, and I am wondering if it could be hadrosaur based on some pictures I saw. Cretaceous is just a guess as most of what I found was from that period. I bought it from the son of a fisherman who found it on the banks of the Kansas River in the Kansas City area. Any help is really appreciated. My dream as a child was to be a paleontologist so this is specially cool to me.

In going through some matrix from the Lance Creek Formation, Late Maastrichtian, Wyoming, which shares much fauna with the Hell Creek formation, I have found some more interesting things since my last posting on this area. I believe that two of the teeth are crocodilian, either crocodile or alligator. The pictures named "unknown 4" look a little like a triceratops tooth, but I don't want to get my hopes up. The pictures labeled "unknown 3," I have no idea - it just looks like a fossil. The hash marks are 1mm.

A Trip to the North Carolina Eocene and Cretaceous
sixgill pete posted a topic in Fossil Hunting Trips
Took a trip last Friday to a quarry that has exposures of the Eocene Castle Hayne Formation and the Cretaceous PeeDee Formation. First let me say it was hot!!! Did I say it was hot? During the day many of us spent extra time in the cars/trucks with the a/c running and drinking extra fluids. The forecast temps were for the high 80's and low 90's, but down in the bowl of the quarry with no wind I believe it was in the high 90's low 100's. However the finds were very good. Almost everyone found at least one Hardouinia kellumi echinoid, several nice enchodus teeth were also found. I saw several crab carapaces along with abundant H. mortonis and Echinolampas appendiculatta echinoids. A massive C. auriculatus was found that in my opinion if the tip was there (feeding damage) would have been close to 4 3/8 inches. Lots of smaller Eocene teeth were found along with some Squalicorax. A multitude of brachiopods were found also, a few different species too. As far as myself I found plenty of brachiopods, Plictoria wilmingtonensis and 2 other species I am working on I.D.ing. Plenty of H. mortonis and E. appendiculatta. I also found one H. kellumi and a very uncommon high domed H. mortonis emmonsi echinoid. Also a beautiful, but small enchodus ferox tooth; a nice small Eocarpilius carolinensis crab carapace and a very nice Entemnotrochus nixus gastropod (slit shell). A few decent teeth and a smattering of other items. H. mortonis on a natural pedestal H. kellumi H. mortonis emmonsi in this last pic the emmonsi is on the left to show the difference in the dome Eocarpilius carolinensis Enchodus ferox tooth Entemnotrochus nixus gastropod and the best of the many H. mortonis

I received some matrix from the Lance Creek Formation, Late Maastrichtian, Wyoming, which shares much fauna with the Hell Creek formation. I have found what I think are 4 croc teeth and what I hope is a therapod tooth (piece). The serrations on the therapod (hopefully) tooth is about 5/mm on the basal side and much finer on the other. The picture doesn't show the finer serrations well, but you can feel them by running your fingernail across it. The hash marks are 1mm. Am I right on any of this?

Hi, Some of you may have seen my post yesterday about unexpectedly stumbling across some ammonites here in the Lower Cretaceous sandstones (Lower Greensand) on the SE Isle Of Wight, on a beach I would never have thought to look. Last night I headed back down there with the intention of properly collecting and testing how abundant this new site was. I was not disappointed. I scrambled along the rocks from Bonchurch and got down there around 7pm, (just a 10 minute walk from my house) and began to systematically scan the beach. Within about an hour I'd picked up more than 50 phragmocones and fragments of ammonites, some of which were a decent size. Phragmocones are by far the most common find, although why this is I'm not sure, possibly due to environmental energy breaking up the ammonites? As far as I can tell the ammonites are parts of nodules which are originating from a hard, glauconite rich bed at the base of the cliff meaning they seem to be from the upper most parts of the Sandrock fm. Some however also seem to come from the Monk's Bay Sandstone fm. (Carstone fm.) which overlays the Sandrock. These were laid down in a shallow sub-tropical shelf sea during the Albian stage (100-113mya), other formations of the Lower Greensand are estuarine/mud flats showing a cycle of sea level rise before the final marine incursion laid down in the Gault (which is also present here on top of the Lower Greensand). As far as species, most of the fragments seem to be members of the Hoplitidae, I've identified one as being Hoplites maritimus, although I think I'll post some up in the ID section as my ammonite knowledge isn't that great. There seems to be much larger ammonites present at the site too, as at the base of the cliff some large moulds could be seen (although the ammonites themselves were gone). There is also an abundance of large pieces of fossilised driftwood, which would likely have originated from land to NE. Needless to say it was a very productive trip (unfortunately the seal didn't return), and it's definitely rekindled my interest in the cretaceous strata here on the island and the fantastic finds it has to offer (I might even start pursuing the dinosaurs again!). If the weather holds I'll head back again this evening to continue investigating the site and the strata, I've also attached images of the finds below (including the larger moulds). The entire haul from the trip, lots of phragmocones An example of the phragmocones Some larger sections of ammonite, although I'm not sure on their ID's

An Ichthyornis-like bird from the earliest Late Cretaceous (Cenomanian) of European Russia

I found this the other day in a NJ brook. The characteristics are consistent with fossilized bone but beyond that, I'm stumped. Does anyone have any thoughts? Thanks! More pics One more...

Hi everyone, Althought I,m a big fan of paleontology I,m still new in this world and sometimes I,m not sure about what I find. I go fossil hunting to a mountain in Valencia, Spain, where I usually find some kinds of ammonites and belemnites. As far as I know the strats in that mountain are jurassic/cretaceous. The other day I found this but I,m not sure if it's a fossil or just a weird rock formation. Any ideas? Thanks for your help!

Hi, I haven't been able to get out to the north coast this weekend to collect as I would normally do, so unfortunately I've got no croc teeth and mammal bones to show. However last night whilst doing some landscape photography along the coast been Bonchurch and Luccombe on the south coast of the Island, I made some pretty nice finds and had a really lucky wildlife encounter! The local bedrock here at Bonchurch are the upper formations of Lower Greensand group, including the Sandrock and Monk's Bay Sandstone Fm. (named after the beach at Bonchurch). I've always presumed the Lower Greensand on this side of the Island is fairly unfossilferous, and being an addict for the tertiary beds up north I've never really taken the time to look so close to home. But last night whilst photographing the sunset in the rockpools, I thought I'd take a little look around, and was really surprised. I searched for about 15 minutes (light was fading) and picked up 5 ammonite phragmocone casts (sorry if that's wrong I haven't properly collected ammonites for years) and 3 fragments of ammonites, one of which I've tentatively ID'd as being Euhoplites. I was pretty pleased with this I've collected ammonites before from around Ventnor but never thought of looking for them here in Bonchurch. The best 'find' of the evening however was a little bit more alive and 'mammaly'. I was picking up the ammonite fragments when I heard a loud breathing sound coming from the water, having done marine mammal surveys and been up close and personal to loads of cetaceans in the wild, I thought it sounded almost identical to a cetacean, I looked up and found myself eye to eye with a Grey Seal instead. Seals, and especially Grey Seals, are not common on the Island so seeing one on our coasts was really lucky! I only had my wide angle lens so the photos are pretty (very) bad quality, but I'm planning on heading down there again this evening with my telephoto, to collect more ammonites, and see if he's still in the area. Overall not a bad trip aha! The ammonite finds, phragmocones and fragments. Euhoplites s.p? The Grey Seal, watching me suspiciously.

This bivalve is 10mm long and from the Lower Cretaceous of Cooke County Texas. It's probably from the Duck Creek Formation but may be from the Ft. Worth Formation. It may even be the Goodland. I'm sure I've seen them other places but I just now brought one home and need to give it a proper label. These formations would be of Albian Stage or Washita Group in Texas. It looks a little like some Ostrea sp. I've seen in some references but not exactly the same. Any help would be great.
