My Jurassic Park: Hell Creek/lance Theropods


Troodon

Recommended Posts

There are two Tyrannosaurs described in the Hell Creek & Lance Formations, Tyrannosaurus rex and Nanotyrannus lancensis. Teeth from these animals are the number one sought after and coveted item by collectors. I don't understand all the hoopla and prices they command since my friends who I collect with know that I'm not a tooth person and prefer bones and claws. However I've been fortunate to find and acquire a few teeth and will post a several of my nicer ones.

My two most favorite T-rex teeth are my biggest and smallest:

The Baby (one of the rarest teeth around) is 1 1/8" and when I showed it to Bob Bakkar and Pete Larson they flipped and never had seen a Rex tooth so small and confirmed it was one. Collected from Garfield County, MT.

My big Trex one is a rooted Premaxillary tooth at 6". One can see the replacement tooth hole at the bottom of the root

T-rex teeth are big and my biggest crown, no root still on the matrix is this 4 5/8" monster.

If your are interested none of these teeth have any work done to them. Minor crackfill to the root of the 6" tooth. Serrations are in pretty good shape.

Here is a very nice tooth from the Lance Fm. The quarry I was in had a about a 2" hardcap before you get to the layer. I force up a one foot slab and look at was underneath it. Just picked it up and :) Attached field photo.

Everyone who I showed this tooth believe it was digested?

Nice toe bone with photo showing its location on the foot. The color difference is that portion that was exposed to the sunlight.

Hand bones are super difficult to find or acquire. Lucked out on this one.

Now will focus on Nannotyrannus start off with a replica of Jane at the Black Hills Institute

My favorite item is a Maxilla with two teeth in it. One of the best preserved I've seen, wish it had more teeth.

These premaxillary teeth are small but because they do not have serrations they are Tyrannosaurid. Most likely Nano but could be Rex.

Few other teeth, largest in photo on right 1 1/2"

The Foot Claws are identified as Tyrannosaurs however they most likely belong to Nanotyrannus

Most likely Nanotyrannus

Same with as Rex, Nano hand bones are very difficult to find or acquire. Here are two of my favorites and image to show you the location of the carpal from the Dueling Dinosaur Hand. I also attached a photo of an adult T-rex hand claw. Quite a difference :o same species??

A Digit I (Dew Claw) metatarsal

I'm not sure if this is Nano or not but its big and I'm not sure what else it might fit

A great publication if your interested in seeing the great illustrations of all T Rex bones. You can pick it up online at the SVP site

Wonderful presentation, and wonderful collection. All of your presentations are too good to describe with words. :yay-smiley-1:

No words need to be said for your T-Rex; your collection is the dream of any dinosaur lover.

As for Nano, those are easily the best Nano teeth I've ever saw. Man, if you ever decide to sell any of your fossils one day, please do PM me!

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!

I've always dreamed of having a collection of premium Rex teeth. It's a bit cliché, but it's a Tyrannosaurus rex dammit haha!

Oh so true why Rex teeth prices are so high
