Not sure exactly what you are referring to but if the question relates to the 1 1/4" tooth all I can say is that Bakker and Larsen both described it as a baby tooth after they examined it.  Proper age classification is " young" not "juvenile" (Hone et al. 2020)

Yes! That’s the tooth I was talking about,  thanks for the help!

Nice collection! Did you find all these yourself?

Oh, that person might it be Brian, if so I saw the vert. It's small fossil world. I've gone collecting at the ranch that sells the Hell Creek material on online auction site and have bought a few from them. Any questions send me a PM.

That publication is available from the SVP website it's Memoir Series No 7. You should be able to buy it on line but I've always wound up calling. It looks at the bones found of Sue, great illustrations

 

if ever you decide to sell one of your T. rex teeth - please let me know! Also - could you pm me the online auction site seller who sells the HC material? Thankyou!

With the Tucson show I have access to some very knowledgeable individuals like Pete Larsen and always use that opportunity to ID material...   I had this pretty complete cervical vertebra for a while, still needs a little cleaning, and tentatively ID it as Anzu but wanted to get an expert opinion.   Pete looked at it and said it could only be Nanotyrannus.  Anzu cervicals are very pneumatic and super fragile and do not preserve very well.   He indicated that Nanotyrannus cervicals are very distinctive from T rex and are another characteristic that distinguishes the two species.   The lack of sutures points to it being an adult.   Super pumped when I heard that ID.

 

 

 

 

 

 

Wow! I'm a vert man, so this is one of my favorite pieces that I've seen from your collection. If you ever get tired of having it around, I might know someone who can help you out!

 

I have noticed that when it comes to smaller theropod vertebrae, I rarely see anything other than caudals available (usually just the centrum). I guess they're more robustly built than cervical and dorsal vertebrae.

Well a lot of what is collected the Hell Creek fm comes from channel deposits so finding any vertebrae with spines is a challenge and like you said they are not as robust as herbivores.
