From the dinosaur coast of Spain this paper addresses the remains of a very large Meglosaurid. Possibly related to the large Torvosaurus reported from Portugal Rauhut OWM, Piñuela L, Castanera D, García-Ramos J, Sánchez Cela I. (2018) The largest European theropod dinosaurs: remains of a gigantic megalosaurid and giant theropod tracks from the Kimmeridgian of Asturias, Spain. PeerJ https://peerj.com/articles/4963/

I wanted to share some of my projects with all of you. A hobby and side business of mine is creating dinosaur sculptures. I do all different kinds of things aside from dinos too, but to keep it relevant, we’ll stick to the mesozoic Featured in my profile picture is my raptor created from scrap metal used to construct railings. I named him Bambi (ironically not a Bambiraptor). Probably more like Deinonychus, he’s a pretty big chicken, but you let me know what you think. As of now he’s my favorite creation, hence why he’s featured in my profile pic. Still trying to figure out the paint job. I wish he’d stop scaring all the birds and deer away...

I found this piece of bone about a month ago and didn't really know what I was dealing with until I started prepping it out. I know that it is theropod based on the hollow structure, this should be at least somewhat visible in the photo of the broken edge. It came from the Redonda Formation in Eastern New Mexico where theropod remains have been found, but nothing identifiable to species. If anyone here can identify the species that would be fantastic, but I really just want to know what bone it is. My guess is the end of the pubis or ilium, but I was hoping for some other opinions.

Hi, Saw this hand claw for sale and wanted to know if it is real. I am a bit suspicious because the tip has a different texture to the back half of the claw. Not sure if there is any repair/restoration but wanted to check to make sure that it isn't a composite. The claw is 4.8cm long and from the Kem Kem (this is the only information the seller has listed). Thanks.

Just recently purchased one of these teeth for the cheap price of $14 dollars from a seller on ebay. I was wondering if anyone with more experience with fossils than I, could tell me if they believe this tooth to be authentic? The ebay seller has all positive reviews. Thank you.

I purchased this from a seller months ago and wanted some insight. The seller bought this from another person who found the fossil itself. However, the seller says that 1, or 2 of the grallator tracks may be exaggerated or not tracks. It seems to me that the Eubrontes track is indeed authentic but I wanted to know what you guys think? These days people scam all over the Internet, but I have faith that the seller was truthful. Thanks in advance for feedback.

I bought this specimen on eBay about 10 years ago, from a reputable seller who had a lot of other Hell Creek material. It was listed as a Tyrannosaurus rex tooth, from the Hell Creek Formation of Montana. It obviously has a lot of repairs and is quite fragmentary, but overall seemed to be a genuine fossil, and for the $350 I paid it seemed like a good deal. But recently, on closer examination, I got a little worried. There is no trace of serrations whatsoever on any part of the tooth, which seems odd- the only non-serrated large theropod teeth I know of are the spinosaurids, which this doesn't resemble overall (and which don't occur in the Hell Creek anyway). I guess what I'm asking the dino tooth experts here is a) Should I be worried about the lack of serrations? and b ) Is there anything else suspicious about this tooth? I tried to get different angles for the photos, but am happy to take more if that might be useful. Any help is appreciated.

Well, following up on my theropod ID topic... Really shocked...in under 8 hours, Tyrannosaurus rex expert Pete Larson gets back to me with this response regarding my fossil being T.rex or not...I guess after 20 buying mistakes, eventually good things do happen ...feels surreal... here’s his response to me: (last picture) Now officially one of my most prized possessions, and maybe the most for that matter..

This is a follow up from another previous topic I started regarding some a past purchases of mine. I thought would be helpful to me and others to post here. All feedback appreciated. I stopped by Trenton state museum recently and David Parris generously helped me out. We ID’d these fossils together. I purchased a fossil sold to me as an allosaurus pelvic bone. I wanted to take it to a professional to see where it could fit, so David seemed to be the right guy. The fossil is fragmented, so from just looking at it, it’s hard to see what it could be period. But if you take a closer look in comparison with another theropod, it becomes somewhat clear. In order to figure out if the fossil was theropod, we took it over to the famous fighting Dryptosaurus skeletons for comparison. He figured it would be a pretty good match because of the size similarIty. He said it’s probable that it could be allosaurus. This is a pic of David with the fossil vs Dryptosaurus

Hi, I have these two toe bones from the Kem Kem. Was wondering if they belong to a theropod or something like a crocodile. The yellow one (1.3 inches) i believe is theropod, but i am not sure about the red one (1.7 inches).

Hi, I saw this for sale, apparently a lower left jaw of a small theropod dinosaur. It is 12cm long and from the Kem Kem beds. It also apparently has predation marks on it. I wanted to ask if indeed this is a theropod lower jaw or if it is something else like a crocodile jaw. Also the description says it is probably from an Abelisaurid, is it possible to narrow it down to family level?. Thanks.

Saw this tooth online recently, it already sold but it was listed as a Tarbosaurus Tooth but it reminds me more of a carcharodontosaurus tooth but then again I am unsure nor familiar with tarbosaurus teeth, what do you guys think? I have included all photos in the listing.

I have a large group of dinosaur eggshell fragments from the Nanxiong Formation of China. As they're isolated fragments I know its difficult to narrow them down to any particular oogenus, but I was wondering if it is possible to say anything about them just by surface texture alone? From what I can gather, eggshells with nodes and ridges from this formation would indicate a theropod eggshell, where as the smoother eggshells are more likely herbivour (probably hadrosaur). I've added pictures of each type. I've struggled to find a lot of detail on Nanxiong eggs which isn't behind a paywall, but what I have found is that there are three types of eggs described: Oölithes spheroides Oölithes rugustus Oölithes elongatus From what I can tell, spheroides is the only egg with a smooth shell and is believed to belong to a hadrosaur. The other two have more heavily textured shells and belong to theropods. I'm planning to sell some of these, so just wanted to double check my assumptions are correct. I also thought it'd be good to clarify, as it's hard to find out a great deal about these eggs online.

Hi All, im currently looking for some of the more rarer/hard to obtain theropod teeth to add to my collection (not the types like T. rex, carcharodontosaurus, nanotyrannus, albertosaurus etc) and have some teeth myself I’d be willing to trade. Please view my post in the member collections section (my small theropod teeth collection) and if you have any theropod teeth or are interested in mine we could maybe come to a deal. Please PM me if you potentially have any teeth for trade and we can go from there. Thanks Paul

I recently received as a gift this very small theropod tooth fragment from Morocco. I labeled it as Theropod indet., but I'm searching for a possibly more specific ID. In my opinion it may be a 2 cm broken tip of a small tooth from a Carcharodontosaur, but I also thought of the Abelisaur possibility. I tend to ignore the relatively unknown Deltadromeus and the hipothetical dromaeosaur, given the lack of good material, but I'm open to suggestions. Here you can see two focus photos of the serrations I took with a small digital microscope. As you see, there is a slight difference between the two sides. Still001.bmp Still004.bmp

I bought this partial vertebrae about a week ago from a moroccan dealer for a very good price (I'm currently trying to identify many vertebrate fossils from Kem Kem, and this is somewhat a pause between two spinosaurid caudal vertebrae and a very big crocodilian mandible articular bone). Since many of you are way more experienced than me regarding moroccan vertebrae, I'm searching for more opinions. This small/medium sized specimen lacks most of the processes, but has some recognizable elements. It is laterally compressed and has a small keel running in its ventral region. I identified It as a caudal vertebrae, and the dealer told me it was a theropod. I don't think he had the skills to seriously identify anything, and I can't understand if It really is a theropod or a crocodile.

Would this be a theropod jaw section its was found at Judith river formation.
