kauffy Posted September 6, 2014 Share Posted September 6, 2014 If it's from the Lower Cretaceous, that means it is older than 106 million years, and that means it is also the earliest tyrannosaur. So I doubt its age. The previous Jurrasic - Cretaceous boundary in Utah was marked by a bed called "the calceri", paleontologist Jim Kirkland and the Utah Geological Survery discovered an important area of Cretaceous beds which sat below this calceri known as the Lower Yellowcat Member part of the Cedar Mountain Formation, these rocks sit on the late Jurrasic Morrison Formation. Within these beds is an extensive fauna of new species of early Cretaceous dinosaurs, newly described iguanadonts, ankylosaurs, Sauropods ect. This tooth was collected with the UGS, and others found in this area most definitely represent a new species of large theropod, the age isn't a question... Just need more of the animal to describe it! "Turn the fear of the unknown into the excitment of possibility!"We dont stop playing because we grow old, we grow old because we stop playing.

hxmendoza Posted February 7, 2015 Share Posted February 7, 2015 It's no show stopper or museum quality tooth but kinda cool non-the-less... From an un described new species of lower Cretaceous Albertosaurus, found in Utah... A few other isolated teeth have been found but no cranial/post cranial elements yet! Cheers chris kauffy, from what formation and locality in Utah is that tyrannosaurid tooth? Link to comment Share on other sites More sharing options...
Runner64 Posted February 23, 2015 Share Posted February 23, 2015 (edited) Little late here but I figured I'd still share with the group. I couldn't decide on just 1 tooth so I chose my four favorite ones. The top left one is a rooted Ceratosaurus, top right is Rugops primus, bottom left is Bahariasaurus, and bottom right is a 4 Edited February 23, 2015 by Runner64 2 Link to comment Share on other sites More sharing options...
Runner64 Posted February 24, 2015 Share Posted February 24, 2015 4 inch Allosaurus tooth, forgot to type Allosaurus for some reason Link to comment Share on other sites More sharing options...
Down under fossil hunter Posted February 24, 2015 Share Posted February 24, 2015 Awesome collection of teeth Runner64! My favourites are the Cerat and Allo. Just be careful with assigning specific id's to some teeth e.g. Bahariasaurus was described with no teeth found (that I am aware of) so until associated material is found no teeth can truly be assigned to it. Additionally Rugops is not know from the Kem Kem beds and is found in Niger (a country that is very difficult to get teeth out of), Rugops remains have been found in deposits dated at 95MYO. Keep up the collecting! 1 Link to comment Share on other sites More sharing options...
Runner64 Posted February 24, 2015 Share Posted February 24, 2015 Yeah I know about Bahariasaurus, I still like the tooth though, looks pretty cool! Thank you though, those two would probably also be favorites. I would really like to restore the allosaurus Tooth though, I think it would look a lot nicer Link to comment Share on other sites More sharing options...
Jesuslover340 Posted February 24, 2015 Share Posted February 24, 2015 Very neat Ceratosaurus and Allosaurus! About all I have is a miniscule Dromaeosaur tooth and worn ankylosaur tooth "Let us therefore follow after the things which make for peace, and things wherewith one may edify another."-Romans 14:19 Link to comment Share on other sites More sharing options...

I am a fan of leaving things as natural as possible however I have seen some miracle workers out there that can cover almost any floor or imperfection.

AJ Plai Posted July 15, 2015 Share Posted July 15, 2015 So many lovely teeth here! Here are my most prized teeth: Tyrannosaurs from North America - a Hell Creek T-Rex, with 2 Judith River tyrannosaurs, possibly Daspletosaurus and/or Gorgosaurus. 1 Link to comment Share on other sites More sharing options...
Troodon Posted July 15, 2015 Share Posted July 15, 2015 Here its my best and my first worn out T-rex tooth i have though its doesnt look so good its a 2.5 inch and has no serrations my proud of my collection this tooth has its my first T-rex tooth though its not big and its worn out though i got it for a very great price for it Nice pair of teeth minor, correction to your comment on the size of the T-rex tooth. For a pre-max tooth (if that's the position better photos would help) its a whopper "BIG" is the correct word. Link to comment Share on other sites More sharing options...
Raptor Lover Posted July 17, 2015 Share Posted July 17, 2015 (edited) My 1.38 inch Tyrannosaurid tooth. It's from either a Daspletosaurus or Gorgosaurus.

-Andy- Posted July 17, 2015 Share Posted July 17, 2015 This is neither the most beautiful nor the largest tooth I have, but it is undoubtedly the rarest in my collection.

Raptor Lover Posted July 17, 2015 Share Posted July 17, 2015 (edited) Thanks you yes its a big tooth and your tyrannosaurid tooth is nice too though its missing a tip and it has serrations mine t-rex tooth doesnt have serrations cause its worn off You're welcome. And thank you. Your Rex tooth is still really cool just for the fact that it's from a T Rex. How did you get it?
