Hi ive been prepping this bone which I thought was a vertebrae. Then I thought partial neutral. Now I’m not sure what it is. It seems to be hollow through the centre with quite a wide cavity.

Hello, I have acquired a T-Rex tooth a few years ago but I now have doubts about its proper identification. The tooth measures 1 inch.

I've collected in the New Jersey brooks for a long time now, and I've found a few pieces of dinosaur material over the years, but I'm interested to know if there are any other public land collecting sites in the US where one can find (and keep!) dinosaur material.

A remarkable dental battery of the hadrosaurid dinosaur, Edmontosaurus annectens. Hadrosaurs had highly sophisticated teeth arranged in these batteries which advanced teeth in a conveyer-belt fashion to replace worn ones. Even the roots of teeth were used once the enameled crowns wore away. This one was in active use and fossilized when the animal died. This battery in particular is special, as it was collected by former forum member Troodon, seen in his "My Jurassic Park" thread here. It comes from a hadrosaur-dominated bone bed.-

British Dinosaur footprints
Brevicollis posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hello, ive seen many of those british "dinosaur footprints" from Sussex and wondered if they're real casts that formed naturally or just funny shaped stones that someone interpreted a Dino-footprint in. In case you dont know what im talking about : The bottom one was identfied as ankylosaurid, all others werent identfied. If someone knows if theyre real or not, or if there are some scientific papers about them that you can link in the replies, Thanks ! -
Howdy all, Seller says these are dinosaur eggshells from the Gobi Desert. Is that true? If they are authentic, the seller also says they are of oviraptor. I took the liberty to compare them to oviraptor eggshells and they didn't match up. I then compared them to some maiasaura shells which have a similar texture and my opinion now is that these are of some sort of ornithopod, possibly a hadrosaur like barsboldia or saurolophus.

Hello beautiful people, I would like you to help me label the following specimens, which come from Morocco. In theory, the 3 teeth in photo "A" are from juvenile spinosaurs. Those in photo "B" deltadromeus. And finally those in the photo "C" Tylosaurus. As always, very grateful for your responses!

Does anyone recognize this as an egg? There are a couple shell fossils on it. I’ve had it for a while and always call it my dinosaur egg as a joke. Then I googled imaged a picture of it and thought it might be. Thanks.
-
I only have these 2 photos. A friend has the fossil and doesn’t know where it came from. It measures about 11 inches in length. At this point that’s about all I know. Thank you all so much for your help to identify.

So, no Kem Kem dromaeosaurids after all?
BirdsAreDinosaurs posted a topic in General Fossil Discussion
Hi all, I just recently had the time to thoroughly read through this recent paper, which describes, amongst other things, how machine learning was used (in combination with other techniques) to identify a possible Deltadromeus tooth. The authors also suggest the presence of a second noasaurid species in the Kem Kem beds, based on a small sub-adult partial vertebra. In the discussion, the authors discuss individual teeth found in the Kem Kem beds that were previously referred to Dromaesauridae by Amiot et al. (2004), Richter et al. (2013), and Ibrahim et al. (2020a). The authors believe all of these teeth do in fact not belong to Dromaeosauridae. They say some are most likely abelisaurid, and others noasaurid (those with strongly distally recurved crowns and those with a non-serrated mesial carina and/or a faint constriction between tooth and crown). All of the dental features used to refer Kem Kem teeth to Dromaeosauridae, are in fact also present in noasaurids and juvenile abelisaurids. To be honest, I never really believed the teeth described in these older papers belonged to Dromaeosauridae. Having said that, there are still some tooth types from the Kem Kem beds that have never been described in scientific literature, which are "dromaeosaurid-like". For example, the ones in Troodon's overview having a twisted mesial carina. However, when you look at lateral teeth of the noasaurid Masiakasaurus, some also have a twisted mesial carina. I think there is still a possibility that some of these small dromaeosaurid-like Kem Kem teeth are in fact dromaeosaurid, but it is quite likely that they all turn out to be noasaurid or abelisaurid. What do you think?- 1 reply

Hi there, a girlfriend of mine has recently brought a property in Peachester, Queensland. This property was previously owned by a geologist, as well as a archaeologist, (... something along those lines ) who had a couple truck loads of "rocks " dumped at the property, for whatever reason. They've since run out of money so they sold up and hit the road.... my friend and I are discovering some amazing things but we have no idea what most of them are - please help... this is just taste of what's there...

I found this tooth on private property in the Lance Formation, and I wanted to know what y’all think. Dr. Bakker told me ceratopsian (Lepto if I remember correctly). He said it was one of the teeth oriented toward the front of the mouth. I’m inclined to believe him, but has anyone else seen this before?

Hello! I found this fossilized bone a few days ago after the big tides in the Jurassic of the Boulonnais region (North of France). I can’t seem to place it… The cell structure looks dinosaur to me, not marine reptile. Would anyone be acquainted with this type of material and have any idea? Thank you very much! IMG_0855.mov

Scapula / femur bone central texas near dino vally in glen rose id please
trap posted a topic in Fossil ID
I found this very hard and heavy petrified fossil? off a hill in a ravine by a natural spring on our property after clearing some land. It has kind of a porous exterior. Perhaps part of the head of the bone broke off partially over time? scapula? A rancher said it looks like a cow bone. It is so old and heavy I just don’t know if I buy that. Is it possible timing wise that it would be a fossilized cow or is it possibly prehistoric? Thank you for having a look. not sure of time period to look at.
