Carbon Posted February 5, 2018 Share Posted February 5, 2018 Hi, Yesterday, I just find with the high tides this vertebrae. It's come from the upper kimmeridge clay of Normandy in France. I know very well the marines reptiles of this age (sauropterygia, ichtyosaurs,etc...) but this vert look very different. Especially with the big furrow at his bottom. I think it's look like a Dino vert but i'm really not sure and I don't know bones of dinos. Could you give me your opinion about it? Many Thanks Carbon. 1 Link to comment Share on other sites More sharing options...

Miocene_Mason Posted February 5, 2018 Share Posted February 5, 2018 Don’t know anything about the deposits, but my gut says iguanodontid caudal vert, no idea why. @Troodon “...whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been and are being evolved.” ~ Charles Darwin Happy hunting, Mason Link to comment Share on other sites More sharing options...
Tidgy's Dad Posted February 5, 2018 Share Posted February 5, 2018 I also thought Iguanodontid. But I thought dorsal. Life's Good! Tortoise Friend. Link to comment Share on other sites More sharing options...
JohnBrewer Posted February 5, 2018 Share Posted February 5, 2018 Looks like my iggy verts so I’m with the others. John Map of UK fossil sites Link to comment Share on other sites More sharing options...
Taogan Posted February 5, 2018 Share Posted February 5, 2018 I would go with Iguanodontid caudal from appearance. Link to comment Share on other sites More sharing options...
Troodon Posted February 5, 2018 Share Posted February 5, 2018 What typically come out of this layer in Normandy? Are dinosaur bones found in this french deposit? Link to comment Share on other sites More sharing options...
Carbon Posted February 5, 2018 Author Share Posted February 5, 2018 Thank you all for your ID. In fact, Iguanodon was the most similar vertebra I had found. So your identifications confirms what I thought. Troodon, there's very few bones of dinosaurs found in the kimmeridge clay of Normandy. Generally one bone only for each dinosaur. More over lot of them was destroyed during the bombing of Le Havre museum in the WW2. Here is a short list of the dinosaurs that I remember : Megalosaurus, Dacentrurus, Dryosaurus, Sauropod... But for me, never Iguanodontid has never been mentioned. 1 Link to comment Share on other sites More sharing options...

Since you are in a mixed fauna its difficult to say. It looks dinosauran and more like a cervical vertebra because of the attachment points of the processes in your first two photos. Unless I'm not seeing them correctly. 2 Link to comment Share on other sites More sharing options...
Carbon Posted February 5, 2018 Author Share Posted February 5, 2018 Thanks Troodon for this informations. I'll try making better photos soon. May be on Wednesday. According to this article, Iguanodon is recorded in the Uk Kimmeridge clay. http://jgs.lyellcollection.org/content/36/1-4/433 1 Link to comment Share on other sites More sharing options...
Troodon Posted February 6, 2018 Share Posted February 6, 2018 Believe that is an 1880 paper, are you sure that is still valid and not Cumnoria prestwichii or Camptosaurus prestwichii. I'm not that familiar with all whats going on in that Jurassic assembladge 1 Link to comment Share on other sites More sharing options...
paulgdls Posted February 6, 2018 Share Posted February 6, 2018 Hi As Troodon says its now Camptosaurus prestwichii , see https://cdn.palass.org/publications/palaeontology/volume_23/pdf/vol23_part2_pp411-443.pdf Only trouble is, I think your vertebra is twice the size of those figured in the paper but an entry in Wikipedia says it could be over 26 feet long so perhaps the type specimen is small. regards Paul 2 Link to comment Share on other sites More sharing options...

Carbon Posted February 6, 2018 Author Share Posted February 6, 2018 Here news photos of this vert. Sorry Troodon, I haven't looking the date of this paper. In fact, it's very old ! Papers about Camptosaurs looks very interesting. Thank you for them. But there's no furrow at the bottom of figured vertebras... 1 Link to comment Share on other sites More sharing options...

Troodon Posted February 6, 2018 Share Posted February 6, 2018 Looks like a cervical of a big animal. I would be surprised if its a Camptosaurs 1 Link to comment Share on other sites More sharing options...
paulgdls Posted February 6, 2018 Share Posted February 6, 2018 Looks similar to the fourth dorsal of Allosaurus so could it be from a theropod? Paul Link to comment Share on other sites More sharing options...
Troodon Posted February 6, 2018 Share Posted February 6, 2018 Yes because of size. I still believe it's a cervical or 1st Dorsal. This is 4 & 5 Allo Dorsal and the ventral surface is straight or curved. The cervicals or first D there is a step like you see in his centrum 3 Link to comment Share on other sites More sharing options...
Carbon Posted February 7, 2018 Author Share Posted February 7, 2018 Thank you paulgdls and Troodon for this figures. With the step and the acoelous/amphicoelous surfaces it's really a mix between the E of each figure. Like on the E vertebra of the first figure there's little furrows at the marge of the centrum. So for you it's really dinosaur and probably more a theropod? Link to comment Share on other sites More sharing options...
paulgdls Posted February 9, 2018 Share Posted February 9, 2018 As you know, very little is known about dinosaurs from this age, but it could be a cervical of Juratyrant langhami or similar. Thanks for posting. I'll ask Steve Etches what he thinks. Paul 1 Link to comment Share on other sites More sharing options...
Carbon Posted February 10, 2018 Author Share Posted February 10, 2018 I know there's very few informations about dinosaurs from this age, more over it's isolated and eroded vertebrae... I like sharing this kind of fossil. For me undetermined fossils are much more interesting ! Thank you for asking Steeve Etches. I really have to visit his museum one day ! I'm collecting fossils for kimmerdige clay from many years now and M. Etches is a legend for me. 1 Link to comment Share on other sites More sharing options...
