Troodon Posted November 2, 2015 Share Posted November 2, 2015 (edited) I have already covered a portion of my United States collection with my other Jurassic Park topics. What remains in the US is the remainder of my Hell Creek/Lance Formations collection and the rest of the US. This topic will cover "Rest of the United States" and includes some very difficult to obtain material from Arizona, New Mexico and Texas. Lets start with the Lone Star State - Texas Agujaceratops mariscalensis My prize possession a partial Chasmosaurus skull a member of the Ceratopsian family in the late Cretaceous. This animal at 5-6 meters was much small than a Triceratops which was around 9 and from an older age. The skull is unrestored with a good part of the top section as well as the Lower Beak. I added images to show you in RED what portion I have and one of the complete animal. What is interesting about this skull is that there appears to be a healed hole in the center. Is this a bite from some nasty theropod or an injury, who know, but there are no other wound marks and the hole is round. Nice to speculate. Acrocanthosaurus atokensis A carcharodontosaurid of North America this predator ruled Texas in the early cretaceous. Good size theropod. Teeth look a bit like its Moroccan cousin. My only specimen from this theropod is a tooth. Edited November 2, 2015 by Troodon 11 Link to comment Share on other sites More sharing options...
Troodon Posted November 2, 2015 Author Share Posted November 2, 2015 (edited) Protohadros byrdi Herbivors also existed in Texas and Protohadros was an Iguanodontid. Nice example of a tooth. Hadrosaurid indet. A couple of undescribed Hadrosurus teeth. Next we move on to the Grand Canyon State - Arizona Dilophosaurus wetherilli An early Jurassic dinosaur which gained some fanfare in the Jurassic park movie. About the height of a human it was about 7 meters long and had an unusual crest on top of the skull. Its unknown what its function was but all and all a very nasty looking dinosaur something you would not want to meet. My only specimen from this theropod is this beautiful tooth. Ammosaurus major An early Jurassic Sauropodomorpha little is known of this dinosaur and small at 4 meters. The specimens in my collection include a hand digit and foot claw.

Troodon Posted November 2, 2015 Author Share Posted November 2, 2015 From the Land of Enchantment New Mexico is a red state. All my material is Triassic, small and from the Bull Canyon Formation. Mostly small teeth and some claws. Coelophysis is found here and some of these teeth belong to this very early dinosaur but I find it difficult to distinguish between species. Herrerasaurids are also found here one of the very first dinosaurs. Chindesaurus bryansmalli is one and found in the southwestern United States. Its a small theropod a couple of meters long. Some very small theropod teeth. Scale is 1mm Theropod Claws Edit: I've learned alot since I posted these Triassic teeth and really question the ID of these teeth. Recent publications have given me new insights into this fauna. 10 Link to comment Share on other sites More sharing options...
Troodon Posted November 2, 2015 Author Share Posted November 2, 2015 (edited) On to the Centennial State Colorado. My only cretaceous specimen other than the ones from the Morrison is a Dromie tooth. From Big Sky Country, Montana two items from uncommon formations St. Mary's and Eagle Sandstone are two Tyrannosaurid toe bones. Now we move to the east where finding dinosaur material is near impossible but some are found. My localities include Maryland, North Carolina and Mississippi From Maryland is a Allosauroid type claw extremely rare.

jcbshark Posted November 3, 2015 Share Posted November 3, 2015 Those are some awesome specimens you have there, the colors on the NM material looks like stuff I find in bone valley Every once in a great while it's not just a big rock down there!

Runner64 Posted November 3, 2015 Share Posted November 3, 2015 Nice collection of US fossils. Just curious but have you seen any other Acrocanthosaurus teeth for sale before? That is probably one of the hardest teeth to get on my bucket list. Link to comment Share on other sites More sharing options...
Troodon Posted November 3, 2015 Author Share Posted November 3, 2015 No otherwise I would have bought it Link to comment Share on other sites More sharing options...

I've never seen a real Acro tooth before. It is amazing how much it looks like a Carch tooth. I've only seen one other Iguanodontid tooth from Texas and that was on ebay a number of years ago. I didn't bid on the tooth, I don't know why! Another one of my dumb decisions! I know it's not a dinosaur but do you have any Revueltosaurus teeth from Arizona or New Mexico?

Sadly, I think you're right haha. I've seen several in collections but none have popped up in the last few years. Might need to scratch it off and replace it with another! I'm still going to keep my eye out for one though. Maybe I'll get lucky one day. Link to comment Share on other sites More sharing options...

There were a number of dealers/diggers a long time ago that found this material and had it at shows. Long gone... Link to comment Share on other sites More sharing options...
Dracorex_hogwartsia Posted November 3, 2015 Share Posted November 3, 2015 I'm curious about the Dilophosaurus tooth. Did you buy that from John at The Natural Canvas? Link to comment Share on other sites More sharing options...
Troodon Posted November 3, 2015 Author Share Posted November 3, 2015 I got that at the Tucson show may have been John but there were dealers there that were not around today. Link to comment Share on other sites More sharing options...

The only chance of getting this type of tooth is like Troodon has said before, you have to develop contacts. You're not going to see this type of tooth on ebay. And then of course you need money! Lot's of money! This type of tooth is not going to be cheap! 1 Link to comment Share on other sites More sharing options...
Dracorex_hogwartsia Posted November 3, 2015 Share Posted November 3, 2015 I got that at the Tucson show may have been John but there were dealers there that were not around today. I've still got some of John's old catalogs and if I'm not mistaken, your tooth is in it. Link to comment Share on other sites More sharing options...
Troodon Posted November 3, 2015 Author Share Posted November 3, 2015 Cool, boy those books were pre-web and he had some neat stuff in them. I go to Tucson with the book and most of the items were sold out. I don't see him getting that kind of material any more. Link to comment Share on other sites More sharing options...
-Andy- Posted November 3, 2015 Share Posted November 3, 2015 You have two teeth here that are rarer than what most collectors would have in their collections. Looking forward to meeting my fellow Singaporean collectors! Do PM me if you are a Singaporean, or an overseas fossil-collector coming here for a holiday!

Troodon Posted November 3, 2015 Author Share Posted November 3, 2015 They seem to have generated lots of interest with a number of PM interested in buying them, not for sale sign was out Personally I would take the AZ and MD claws any day over those teeth but I' m a claw guy.
