Bilmor Posted March 20, 2017 Share Posted March 20, 2017 Hi, I bought this claw in Rissani, Morocco for a week ago. It was found in the Kem-Kem area. But I'm not sure the species it belong to. Any suggestions? Link to comment Share on other sites More sharing options...
Troodon Posted March 20, 2017 Share Posted March 20, 2017 Well my guess it's supposed to be a Spinosaurid hand claw. I'm very suspicious of composites or complete fabrication etc with claws like this. Can you post pictures of the other side and some close up of claw. The Moroccan dinosaur community are real artisans. Forgot, welcome to the forum Link to comment Share on other sites More sharing options...
Bilmor Posted April 2, 2017 Author Share Posted April 2, 2017 Hi again, here`s more pictures of the claw. I guess it som repair and glues in it. Can someone give a review ? or advice? Link to comment Share on other sites More sharing options...
LordTrilobite Posted April 2, 2017 Share Posted April 2, 2017 I think the middle might be genuine. But I think the base is completely constructed with some bone material in it here and there. It looks like the tip migth also have been restored. Hard to tell from the photos though. Olof Moleman AKA Lord Trilobite Link to comment Share on other sites More sharing options...
RJB Posted April 2, 2017 Share Posted April 2, 2017 Im no dino claw expert, but the second I looked at this I thought it didn't look right. I believe LordTrilobite is spot on with his assessment. RB Link to comment Share on other sites More sharing options...
Susan from PA Posted April 2, 2017 Share Posted April 2, 2017 I'm not an expert on these claws either, and determining what is real and what isn't on these claws can be tricky sometimes. I have to agree with LordTrilobite. I think the middle portion of the ventral surface is real, the area that is a lighter white in color. The rest of it looks highly suspect. We can ask @Troodon Link to comment Share on other sites More sharing options...
fifbrindacier Posted April 2, 2017 Share Posted April 2, 2017 I'm like Troodon, the moroccan dinosaur community are real artisans. Could you show us a photo of its base surface ?

Troodon Posted April 2, 2017 Share Posted April 2, 2017 Thanks for the additional photos but the images are all from one side. Would like to see the other side. The first thing that strikes me about the claw is the overall shape: long, straight and thin. I'm not an expert on Spinosaurid claws but that's not the typical morphology of ones I've seen but... . The color variations in the bone also have me concerned and raise the issues of compositing but I would have to hold it to really determine what's been done but I dont see the exaggerated joint issues of a composite and the lines look good so does the blood groove. Like others have said the proximal articulation appears to have been reconstructed. So lots of concerns that photos of the other side might help clarify. Here is your typical Spinosaurid hand claws. There is digit to digit variations but stout at one end and slightly recurved 4 Link to comment Share on other sites More sharing options...
Peat Burns Posted April 2, 2017 Share Posted April 2, 2017 Try exposing it to UV light. This can help determine parts that are authentic vs parts that are fabricated. Link to comment Share on other sites More sharing options...
Bilmor Posted April 2, 2017 Author Share Posted April 2, 2017 Thanks or all answers. Here`s some more pictures from both sides. I try uv-light and it glow like other bone material I have, for example a big vertebra (100 % real) I have. I think I`m not sure what I shall looking for ?

Bilmor Posted April 2, 2017 Author Share Posted April 2, 2017 ...and I`m 100 percent sure it is repaired and glued here and there. Agree with you Troodon that the shape is little strange. The seller/dealer thought is was a birdlike claw? Link to comment Share on other sites More sharing options...
Troodon Posted April 2, 2017 Share Posted April 2, 2017 The biggest issues with vertebrae is that the Moroccan like to composite the processes on it. Post it let's take a look. I hate to ask for more pictures but can you take a closeup of this Link to comment Share on other sites More sharing options...
Peat Burns Posted April 2, 2017 Share Posted April 2, 2017 UV light isn't always definitive or easy, but this site has some photos of fossils under UV showing anomalies that indicate restoration. http://singapore-fossils.wixsite.com/singapore-fossils/single-post/2017/01/01/Fossil-Basics-Real-or-Fake 1 Link to comment Share on other sites More sharing options...
Bilmor Posted April 2, 2017 Author Share Posted April 2, 2017 Of course I send pictures, I`m very happy for advise and help. Here`s two more of the tip Link to comment Share on other sites More sharing options...
Bilmor Posted April 2, 2017 Author Share Posted April 2, 2017 ...and I have a question about this trilobite. It`s for sure real (buyer from a very good taxidermist i Morocco) As you see it`s little translucent (like some russians) and you can see a our through it. But can someone tell me what kind of species it is? or family? Link to comment Share on other sites More sharing options...
Troodon Posted April 2, 2017 Share Posted April 2, 2017 Thank you. I don't see any evidence of compositing on the tip just repair with glue and matrix. The claw is odd, not prepped very well, a few repairs but except for the back end may be good. Not a bug expert. Suggest you post it as a separate topic to get all the Trilobite experts looking. If you have a specific locality with size it would be helpful. 2 Link to comment Share on other sites More sharing options...
Bilmor Posted April 2, 2017 Author Share Posted April 2, 2017 Thank you Troodon. I have a good friend with name Jørn Hurum (dinosaur expert at Natural History Museum, University of Oslo) Will vist him tomorrow. Her said the same as you from the pictures! He thought (like you) at this was from a spinosaurid species. Thank you all for answers and advises. best wishes Morten Bilet Norway Link to comment Share on other sites More sharing options...
Troodon Posted April 2, 2017 Share Posted April 2, 2017 Glad all of the members on the forum can help and provide input to your claw. Your friend Jørn Hurum will be able to have a very close look at the claw and provide an experts view on what was done to it. Would love some feedback so we can educate ourselves.

Bilmor Posted April 3, 2017 Author Share Posted April 3, 2017 Yes I will give feedback as soon I know something about this claw. Link to comment Share on other sites More sharing options...
fifbrindacier Posted April 7, 2017 Share Posted April 7, 2017 I would say a kind of proetoidea, but i know very little about trilobites. We should wait @piranha or @FossilDAWG.
