"Nanotyrannus"? ...the doctors will see you now. #FossilFriday @jamesnapoli

@DakotaDinos I have only skimmed through Carr et al., but I am in agreement with there methods, analysis, and conclusions.

@PeteLarsonTrex Do have any thoughts to share on this? Splitting T. Rex Into 3 Species Becomes a Dinosaur Royal Rumble nytimes.com/2022/07/25/sci…

@PreparationsCk No that’s a big tooth!!! Skull should be there.

@TyrannosaurCarr Nice art work!

@TyrannosaurCarr It’s owned by the Government of UAE, but why would it matter as long as it’s on public exhibit and available for research?

@TyrannosaurCarr Almost all public museums (and libraries) started with a nucleus of specimens (or books) from a private collection

@TyrannosaurCarr With all your arm waving about STAN we now know that he is in a public museum.

@TyrannosaurCarr It’s a good thing that private people own books, because public libraries are no longer safe repositories

@TrieboldPaleo @Smitty227Smith He is on a mission.

@PeteLarsonTrex @Smitty227Smith But still present on them in his SVP poster this year. His choice it seems. We won't pretend to understand it,

New Years resolution: find ways to help researchers obtain access to privately held fossils to substantially increase the fossil data base.

@TrieboldPaleo @Smitty227Smith This was in answer to Tom Carr, whose New Years resolution was to not study privately held fossils😳

@Smitty227Smith @PeteLarsonTrex I don't think the resistance is on the private side in this case.

@TyrannosaurCarr Data is data. As scientists, we should do our best to accumulate data. As long as it is real, what scientist would close their eyes?

@TylerGreenfieId Published in Tyrannosaurus rex: the Tyrant King, Larson and Carpenter. 2008. Indiana University Press

@PeteLarsonTrex Have you published these yet? I'm sure a lot of paleontologists and paleoartists would be interested to learn that T. rex had osteoderms.

Wait have orbital osteoderms in T. rex actually been found?

@PreparationsCk Lige was an awesome human being who cared about others. We will all miss him.

@DakotaStandard Sort of like cutting off your nose to spite your face.

Disappointed? Yes. Surprised? Not in the least.

@PreparationsCk I LOVE show and tell. And I always learn something when asked questions or shown photos.

@LukeSky26579838 @EthanTownsendM8 @CoastalPaleo @DakotaDinos @CMNHvertpaleo @histo_holly There is no pneumatic chamber behind the foramen in the Dasplstosaurus specimen, and even if there was, why do all Nanotyrannus have it but no T. rex specimen has it?

@EthanTownsendM8 @CoastalPaleo @DakotaDinos @CMNHvertpaleo @histo_holly @PeteLarsonTrex The pneumatic foramen is also seen in an isolated Daspletosaurus quadratojugal. But I don’t think Nanotyrannus deniers should celebrate yet. 😉

Last week @histo_holly and co. published new #histology research on the juvenile tyrannosaur "#Nanotyrannus lancensis", the holotype of which resides in our collection. Based on their findings, this specimen is #Tyrannosaurus rex. Is it time to change the label? #fossilfriday

@Collinson_C @LukeSky26579838 A T. rex tooth is easy to Differentiate from a Nanotyrannosaurus tooth and will bring 5 to 10 time’s as much. Why do you suppose most Commercial dealers are not on board with selling Nano teeth as juvenile T.Rex? I suspect that experience and honestly both play a big part.

@LukeSky26579838 @PeteLarsonTrex Ok, I have shit tones of problems with the way commercial dealers frame this debate, it’s extremely dishonest. They are alway “we want the palaeontologists to examine our specimens.” “We’ve begged them to come see it.” “They just refuse.”

@PeteLarsonTrex @SympanScience You speak as though natural variation in a pop of animals through time is not a thing.

@Collinson_C @LukeSky26579838 You are free to speculate as much as you want. Or you could come (or go) to see and measure the specimens for yourself. Wyrex hand is completely un-restored. As are the bones I posted for Sue and Jodi, and all but the unguals for Pecks Rex. Also no reconstruction on Sereno’s hand

@LukeSky26579838 @PeteLarsonTrex Those shiny smooth areas, at the back and along the bottom are reconstructions.
