Troodon Posted January 31, 2018 Share Posted January 31, 2018 A few items I recently picked up at the Tucson show. Others will follow Nice size Pterosaur upper beak. Big Dorsal from a Theropod - needs to be prepped to remove matrix glued on the bone. Will tackle after the show. Spino Metatarsal Very Arthritic bone.. believe its Phalanx 14 Link to comment Share on other sites More sharing options...
Troodon Posted February 1, 2018 Author Share Posted February 1, 2018 A cool bone that a friend of my found and sold it to me at the show 6 Link to comment Share on other sites More sharing options...
Troodon Posted February 2, 2018 Author Share Posted February 2, 2018 I wish they would leave these bones as found. Spent a couple of hours removing the glued sand blobs at both ends but decided to leave the matrix at one end to have a record of what it was in. Believe it to be a Pterosaur bone not sure which one could be carpal. The bone is very thin and hollow which is why I made that call. Nice size. 5 Link to comment Share on other sites More sharing options...
Troodon Posted February 4, 2018 Author Share Posted February 4, 2018 I started working on cleaning the dorsal vertebra I posted above and initially thought the material on the neural spine was matrix. It turned out to be bone and I'm guessing disease or possibly arthritis. Anyway very cool and its on both sides the full length of the spine. 5 Link to comment Share on other sites More sharing options...

Is there a term used to describe fossils showing disease or healed wounds? Looking forward to meeting my fellow Singaporean collectors!

Nimravis Posted February 4, 2018 Share Posted February 4, 2018 Frank, nice acquisitions- i have always wondered what type of app do you and others use to put together the pics the way that you do? I’m always impressed. Link to comment Share on other sites More sharing options...
paulgdls Posted February 5, 2018 Share Posted February 5, 2018 Frank The Rebbachisaurus vertebra is fantastic. Here is a neural spine which I picked up while visiting El Begaa. I've never been sure what it is but you've confirmed it. I think the roughened area is for the attachment of the interspinous ligaments, which must have been massive. Below it is a photo of a Carcharodontosaurus humerus I bought at the same location. regards Paul 6 Link to comment Share on other sites More sharing options...

The humerus is beautiful nice find. 1 Link to comment Share on other sites More sharing options...
jpc Posted February 6, 2018 Share Posted February 6, 2018 I am also in the ligament attachment camp on that vert. I have seen them on T rex, ceratopsians and Morrison Fm sauropods. 3 Link to comment Share on other sites More sharing options...

I'm not very good since do not have the patience to set up for the best photo with lighting. But it starts with a good picture and Adobe Photoshop Elements does the rest. It helps to have good subject matter. 1 Link to comment Share on other sites More sharing options...
Troodon Posted February 12, 2018 Author Share Posted February 12, 2018 Pick this nice looking bone from one of the Moroccan Tents. Not sure what its from Dinosaurian or other Reptilian but leaning to it being a Metartarsal of a Crocdyliform Similar to this one 4 Link to comment Share on other sites More sharing options...

Need to check out that Vertebra but could be a Spino cervical Yes definitely a Spinosaurid cervical vertebra. Is the neural spine broken off? Because it looks a little short. The underside of the centrum can show whether this is Sigilmassasaurus or Spinosaurus. As Sigilmassasaurus has a posterior triangular rugose plateau on the ventral side. Other Spinosaurids don't have that feature. Very nice pieces. Olof Moleman AKA Lord Trilobite Link to comment Share on other sites More sharing options...

There is no platform on the bottom, first thing I looked for, why I labeled it Spinosaurus. The neural spine has an area that is missing on the anterior side but the rest looks to be all there, I do not see any breaks . Its from a juvie so the spines might not be fully formed?

I've not seen a whole lot of complete cervical Spinosaurus vertebrae. But from what I have seen it does seem like Spinosaurus has taller neural spines on the neck than Sigilmassasaurus does. Though what I'd really like to see is a definite Sigilmassasaurus dorsal vertebra that is complete so we can find out if it had a sail or not. There are dorsal vertebrae with the same rugose ventral plateau, so my hunch is that those also belong to Sigilmassasaurus even though none such vertebra has been described.
