- T. rex is renowned for its title as king of the dinosaurs, but before Tyrannosaurus was king, another tyrant ruled North America, one finally revealed to science as of 2024! Meet T. mcraeensis!
Splendid summary and good, steady narration.
^.^ You're too kind
At first, I was in love with idea of tyrannosaurines coming from Asia into North America displacing albertosaurines, now I digging the idea of tyrannosaurines and chasmosaurines taking over vacant niches of albertosaurines/daspletosaurines and centrosaurines, respectively. If only chasmosaurs managed to spread into Asia like the tyrannosaurines.
On a similar note: while I am on the side that suggests Nanotyrannus was a juvenile form of T. rex, I can also get behind the idea of it being a North American equivalent of Alioramus.
I'm just glad it's not another contradictory Spinosaurs piece. Can we just ban it till something concrete comes out?
ok
nice video
THX!

Eventually, I do believe that someone is going to debunk this paper
May I ask a question or two?
Didn't Tyrannosaurs come from Asia to North America?
Didn't Daspletosaurus evolve in Tyrannosaurus?
The thing about the Daspletosaurus evolving into Tyrannosaurus bit is that it's not widely supported. It was certainly a popular idea during the 2000s, but as we've gotten a better understanding of tyrannosaur diversity over the past 2 decades, it's an idea which was already a bit out there, even less support
As for the tyrannosaur origin bit, the consensus does seem to be that eutyrannosaurs emerged in Asia and expanded their range throughout North America yee, where they evolved into at least 2 families: dryptosaurids and Tyrannosaurids. Within the family Tyrannosauridae, there were Tyrannosaurines and Albertosaurines (possibly 3 if you subscribe to Daspletosaurines). Tyrannosaurines is the subfamily Tyrannosaurus belongs to
