ｱｼﾞｱﾃｨﾗﾇｽｪ……w
福井の特別展『獣脚類2025』でこの論文の著者と、標本の前でこの話めっちゃしてたんだよねｗ

論文出版おめでとうです！

@BadlandsColt We’re did it

I warned you guys. @GormRaun

Guy at the conference I’m attending: “you work on tyrannosaurs? What do you think of Asiatyrannus and Raptorex getting nano’d into Tarbosaurus?”
Me:

The final version of the paper is out! https://t.co/SRU3r0LTVd
Have a good read!

[Gorm Skouboe Raun @GormRaun]

@MiloGaillard3 @TheAnimalCrewz Thanks, and don’t worry, expect more Tarbo stuff in the future

[Gorm Skouboe Raun @GormRaun]

@MiloGaillard3 @TheAnimalCrewz That’s not to say it isn’t good to be vigilant of illustrations, after all, there is a human aspect to them

[Gorm Skouboe Raun @GormRaun]

@MiloGaillard3 @TheAnimalCrewz Furthermore, Illustrations are and have been the primary way for researchers to figure their papers, even after photographic print. Which is why you don’t typically see major criticisms of papers such as Currie (2003).

Reclassification of Asiatyrannus & Raptorex as Tarbosaurus

@Monster77571319 @beazelgoose @SomniosusW @knight_Steve_ Typically, the Nemegt is considered Maastrichtian in age, but like, broadly speaking. Many formations unfortunately lack the volcanic (or other beds) that can absolutely date the rocks of the cretaceous.

[Gorm Skouboe Raun @GormRaun]

@TM9380 Yea I think most people for some reason have this idea that Tarbosaurus is only in the 10 meter range, when they most definitely were average rex sized.

[Gorm Skouboe Raun @GormRaun]

Fun little size est. about Tarbosaurus, the largest femur known has a circumference of 480 mm (MPC-D 107/2), giving a weight estimate following Campione et al. (2014) of 5.02 tonnes. Scaling PIN 551-1 from that gives a circumference range of 552 to 568 mm... 7.39 to 8.01 tonnes.

[Gorm Skouboe Raun @GormRaun]

Similarly sized Tyrannosaurus skulls have femurs ranging from 520 to 580 mm in circumference, fyi.
Giving a weight range of 6.25 to 8.46 tonnes.

[Gorm Skouboe Raun @GormRaun]

@TomHoltzPaleo @NatSciChannel Agreed

[Gorm Skouboe Raun @GormRaun]

@knight_Steve_ @omegafreelancer @Lythtras The Alioramines are pretty distinct from Tarbo imo

[Gorm Skouboe Raun @GormRaun]

@tylerstoneart @raptor_chatter @TM9380 I think it’s easy to see Raptorex as more basal when the original reconstruction depicted it as such, the individual bones however, just won’t be uniquely different from Tarbo

[Gorm Skouboe Raun @GormRaun]

@tylerstoneart @raptor_chatter @TM9380 My own insight: I had the opportunity to assess over 25 Tarbo skulls and I’ve yet to see a Rapto character that isn’t also in at least some Tarbos, it’s a really variable taxon, which I got into at SVP in Birmingham 1/2

[Gorm Skouboe Raun @GormRaun]

@omegafreelancer @ChaseBrownstein It comes up in my upcoming work that deal more with ontogeny than this chapter, if that’s any consolation
