Hi! I got this Hadrosaur caudal vert from the two medicine formation. in Pondera County. I was wondering what part of the tail this bone would have come from? the seller says it is likely a proximal vertebra, but couldn't give any details on its placement. Is there any possible way you can tell what part of the tail this fossil belonged to? assuming a grown individual of the species. If exact placement isn't possible, Ill settle for general region. The centrum of the Vert is 2.7 x 2.3. x 2.2" and the process is 7.6" long in a straightline including the anterior points

Sloth Claws And Claw Cores: What's The Difference?
MeargleSchmeargl posted a topic in General Fossil Discussion
I've seen people collecting Megatherium claw cores on this site for a good while, but I never did get a good look at what a complete claw would look like (since judging by the fact that they're cores, there'd have to be more to those claws in life). What other components would make up the claws of animals like Megatherium, and what would a complete claw look like? -
Hello together, I am not entirely sure if the fossil ID section is the right place for this, but I am hoping for information on a fossil specimen, its not one I hold in hands, but a ct scan, and I think I may not post pictures because they are copyrighted. While looking for new inspirations for my model building I took a close look at this wonderful ct scan of a Simosuchus clarki skull. A pugnosed crocodile, how sweet is that? I wonder two things: -how is that bilateral bone called that in many crocodiles protrudes downwards from the skullbase reaching between the ma

So...I have some questions about sclerotic rings. In addition to supporting large eyes, resisting pressure, etc. how do they work? I ask as I see four basic forms across species, extant and extinct. the first is a fixed ring fused to the frontal and zygomatics. the second looks to be a fused or partially fused ring that is around the iris the third is a ring of small plates held together by connective tissue and the fourth looks like a camera iris Where my confusion arises is with the third and fourth and some birds and fo

There are a lot of experienced dinosaur collectors out there but for the newbie I thought a topic on the anatomy of bones and teeth would be beneficial, in plain english. Avoids reading pdf's that are difficult to get through the technical terms. Orientation Skeleton The specific sketal structure of a dinosaur varies between theropod and herbivore but the major elements are typical. Skulls of dinosaurs are not comprised of a single bone but many elements See the osteology of a Trex skull on page 2 The holes in the skull are identified as

Hi I was wondering if anyone could help me identify some of the key anatomical features of the calyx of this crinoid (Apiocrinites elegans) and any anatomical features of this brachiopod (specimen unknown). I have trawled and searched but am having limited success so thought there might be a fair few people that would be able to lend a helping hand on here! cheers mark

Hello evereybody, I dont know if this is the right place to post this but I would be interested to learn more about mosasaur skull three-dimensional anatomy. Do someone know where it is possible to buy accurate mosasaur's skull cast? I am looking for something more educational than decorative and ideally not too big. I know that there are plenty of interesting stuffs on the web but from my experience in human medecine nothing is as good as a three-dimentional model to understand complex anatomical structure like the skull. Thanks for helping!

This was a really cool museum. I especially liked their selection of fish and marine reptiles. They also sported a largely complete tyrannosaurus skeleton, an Ammonite five feet tall and four feet wide, and a large completely intact mammoth. Pelagosaurus Typus A Mary Anning Icthyosaur (Two more were present) Plesiosaur Eryops A large fish (One of the Many on display) A perfectly preserved Crinoid The nicest ammonite (My opinion) Perfect spiral pattern And much more that we d -

Hi all! Under the presumption these are echinoderm I've been searching for anatomical features, particularly disarticulated crinoid and archaeocidaris of which both are plentiful in the matrix. In my searching I've been unable to find anything that even remotely resembles these pieces. Any input is much appreciated. Plattsburg fm. - Hickory Creek sh. I attached a group photo of some of them I found, followed by 4 select specimens showing each side front and back. For scale, field of view is ~1cm. Group shot Front
