Do you have dinosaurs from every formation in this world man?

Christ, you probably have more Tyrannosaur teeth than I have ammonites.

No I missing a few formations :P but working hard to fill those voids.

I know I don't have to tell you but one cannot have to many Tyrannosaur teeth. :D

Hey Troodon,

What a gem of a post, truly exquisite!!! Just to state the obvious .. I love how you're prefacing the post with a map, an illustration or two, followed by a sequence of beautiful photographs interspersed with information, notes and comments. And then there are the specimens themselves, absolutely wonderful and thank you for putting in the time to put this together like that.

Thanks for the post! Always enjoy going through your posts and seeing your fossils. You have some very nice fossils that I'm sure museums wish to have. Keep up the posting and collecting!

Thanks guys. Just trying to provide some background information and not just pictures. Thought it would be a bit more interesting if I added something about the locality and fossils so I'm glad its appreciated.

I omitted a pretty nice specimen and extremely rare Tyrannosaur Pre-maxillary jaw section with three teeth, missing one. The teeth are associated and not placed in the jaw. There are 8 Pre-maxillary teeth in the skull, four in each side. In the side view one can see the curvature of the front of the jaw. Teeth appeared to be well used.

Hi Troodon,

,

I've just joined this forum, awestruck as most I guess by your collection, just a couple of questions I hope you havent been asked already.

You seem to have the full deck of fossil specimens anyone could possibly wish for. Is there any particular items (just a single fossil rather than a whole skeleton) you'd really covet that's missing from your collection so far?

Secondly I live in UK so am mainly limited to items I can pick up on the web. What other sources do you have for picking up quality items short of digging them up? Is there a lot of trading done and fossil shows and conventions in the U.S?

Thirdly, please can I be written in to your will :)

Thanks

Welcome to the forum. Thanks, glad your enjoying what I posted why I started the topics

I don't have a wish list but if I had to choose an item in an area that I most covet "claws" it has to be a T- Rex hand claw. Never have found one or had an opportunity to acquire one.

Most of my best pickups have come directly from diggers that I have collected with over the years. Short of that I've developed great relationships with dealers from all over the world. Most make it to the Tucson fossil show so I get to meet them in person. Some key ones do not have oneline sites and shows are the only way to see them. Online dealers like Indiana9fossils, FossilEra, Extinctions, Paleosearch, PaleoGallery and Natural Canvas are typical ones I look at for specimens. If you know your material very well eBay is really a great source. I don't get involved with trading.

I'll put you on the will list its quite long and at this point everyone gets a small bone. :)

I've seen claws over the years sold as T. rex hand claws. Some sold by people I think we would both classify as reputable. Is it that you've seen claws sold as T. rex hand claws and you just didn't believe that's what they were or have you actually just not seen one for sale?

Well I have missed out on a few opportunities just bad luck. For the longest time before Anzu w. (Chirostenotes) was understood and this is not very long ago their foot claws were thought to be T.rex hand claws. There is some similarity between the two.

Quite a few claws that I have seen being sold on the web or at shows were very suspicious or simply something else. IMO very few dealers can actually ID one better today than 5 years ago. Not a lot of them floating around so its hard to compare.

You don't see a lot of claws now sold as T. rex hand claws and I think it's for the exact reason you gave, they were and are actually Chirostenotes claws. I remember years ago there were a lot of T. rex hand claws for sale and I kept thinking to myself, where are all these hand claws coming from. After all, they are extremely rare! You don't even find them with T. rex skeletons so why are so many being found as isolated elements. Well, as we know now, they actually weren't T. rex hand claws. I'm glad I didn't buy one back then but I came awfully close. A real T. rex hand claw is going to be a rare find indeed.

I remember seeing a well know Institute selling replica Rex claws and they were actually Chiro claws :(

You kind of wonder if the T-Rexes were kind of embarassed by their little ickle hands so they wanted to hide them from posterity!

It seems to be one of those favourite Palaeontological guessing games , what did they actually use those withered limbs for?

I think arousing the lady Rexettes would have to be my favourite interpretation.

You're right though I haven't seen any hand claws on the market pretty much anywhere except one auction site, makes you wonder what happens to them all given they had as many upper limbs as lower?

Ha ha like your theories.

I don't believe the arms preserve very well why you don't see carpals or hand claws around.

I accidentally, as usual, found additional information on one of my mystery foot claws on post #3. Thought I would pass the information on since you might have one in your collection and it's different.

The mystery claw

In 2008 Nick Longrich published a paper about a new large bodied Ornithomimid that was found in the Dinosaur Park Formation, Alberta that could not be assigned to Struthiomimus or Ornithomimus. It features much larger hand claws and a foot claw that where the flexor depression is unusually deep, see my white arrow.

Compare it to the photo of a Struthiomimus post-10935-0-76581400-1457964774_thumb.jpg

Although my claw was found in Montana the fauna is similar and hopefully one day a taxon will be assigned.
