Possible New Species of Tyrannosaurus in the Ojo Alamo Formation!

I prefer the name Alamotyrannus but a possible second species of Tyrannosaurus is cool.

^Well the chart refers to it under the same genus. There would have to be notable differences between T.rex and T.brinkmani for them to identify the latter as Alamotyrannus. For example, Tarbosaurus isn't called Tyrannosaurus bataar because T.bataar and T.rex have several differences in the structure of their skulls.

^Oh. Well a new species in the Tyrannosaurus genus is interesting.

^Yeah.

Genus is Tyrannosaurus and rex is the species.

^It could not just represent a new species, but also a new genus. Let me differentiate a genus and a species. Tyrannosaurus is the genus, and rex is the species. There can be multiple species under the same genus; for example, the genus Triceratops has both T.horridus and T.prorsus. If there are significant differences between multiple species under the same genus, then it would most likely be re-classified as a new genus.

Another name for the new species could be Tyrannosaurus alamoensis xD

^And this could very-well mean a new rivalry between Tyrannosaurs and Ceratopsids, since Eotriceratops was found around the same area as Alamotyrannus/Tyrannosaurus brinkmani. But then again, there's also Torosaurus utahensis.

Updated to include more information and speculation.

I doubt the existence of another tyrannosaur living alongside T.rex to be honest.

Interesting.

So.... Panthera leo and Panthera pardus aren't able to exist side by side with each other? I guess Lions and Leopards living side by side in the same ecosystem must tear a hole in the universe.

Joking aside, two Tyrannosaurus genus isn't a stretch of the imagination since there are multiple modern day animals that share the same genus living alongside each other. Panthera leo (Lion), Panthera pardus (Leopard), Panthera onca (Jaguar), Panthera tigris (Tiger), and Panthera uncia (Snow Leopard) for an example.

GG I never said that A/T.brinkmani and T.rex coexisted.

Xeno, I'm saying that an Apex predator like Tyrannosaurus I don't think at-least could easily co-exist with another predatory of its own kind. The type of animal it was, its only competition would've been Dakotaraptor in the predatory field. All our knowledge dictates that T.rex was the sole big theropod predator of its region and time.

Tyrant yeah I was just saying in general, great topic btw.

^Do you think that A/T.brinkmani represents a new genus/species, or is it just a rex specimen that was located in the south?

Rex specimen in the south, definitely. There is evidence to suggest T.rex dominated all of America.

^Even the east?

Whole continent.

@GodzillaGorilla:

That doesn't mean there couldn't be two different species of Tyrannosaurs, I mean in Asia, Panthera leo (Lions) and Panthera tigiris (Tigers) have shared eco-systems together and even interacted with one and other... rarely in a violent confrontation but other times they ignore each other.

@Xenotaris

That's a great point!
