JohnBrewer Posted December 19, 2017 Share Posted December 19, 2017 Are they from a juvi rex? If so how do they compare in robustness and serration count to a nano of similar size? John Map of UK fossil sites Link to comment Share on other sites More sharing options...

Have not seen a Nano that size but it's fatness and shape says Rex. I did a study of my Rex and Nano teeth and the smaller the tooth became the density of the serrations became more similiar. 3 hours ago, StevenJDennis said: wow those rex are tiny! very nice.

Maybe send me a dinky rex and I’ll peer review against my nanos 1 John Map of UK fossil sites Link to comment Share on other sites More sharing options...
Troodon Posted December 20, 2017 Author Share Posted December 20, 2017 Spoke to quick. Rummaged through some teeth and found these two. The denticles match that of a Tyrannosaurid and this tooth compression on the tooth leads me to believe its a Nano. Denticles under a scope say Tyrannosaurid. I think its a Nano but something this small ? Now this is a small Tyrannosaurid Tooth. 4 Link to comment Share on other sites More sharing options...

Interesting. I thought the serration count was one of the arguments that was used to differentiate twixt the two by the camp that say nano is a different tyrannosaur? That was why I asked. It it would be interesting if everyone here could a serration count v size of tooth that is rex and nano. But I guess you’ve got more than everyone else put together looking at these threads of yours! John Map of UK fossil sites Link to comment Share on other sites More sharing options...

But I guess you’ve got more than everyone else put together looking at these threads of yours! Well that's the typical understanding but the problem is that everyone uses serrations counts of jumbo teeth which are less dense. However If you compare equivalent size Nano and Rex teeth the difference may or may not be significant. I've seen rex teeth with fine serrations. A better way to differentiate between the two is to look at the other physical features as well as serrations. Identification of isolated teeth is very problematic. 2 Link to comment Share on other sites More sharing options...

I meant with teeth, Rex 's depending on position are not compressed and oval, their tip is rounded/bulbous with serrations continuing from one carina to the other. Nano's are typically compressed with a pointed tip. Variations exist and some are difficult to call. 1 Link to comment Share on other sites More sharing options...

Troodon Posted May 11, 2018 Author Share Posted May 11, 2018 I was thrilled to see this tooth arrived today from my preparer. From my last Summer dig it it took forever to get on the to-do list but we'll worth the wait. The enamel on one side had collapsed into the tooth and bottom section by the root had broken off. It's 5" long and as they say a real plug. The base is 5" in circumference. Hell Creek Formation, Powder River County, Montana 11 Link to comment Share on other sites More sharing options...
