MemberCompsognathusSeptember 09, 2015For years, it was thought the domain of the tyrannosaurs was restricted to the northern hemisphere. Killers like T.rex, Tarbosaurus, and Eotyrannus illustrating a range from North America, to Asia, and also Europe. However, it was assumed these tyrants never reached the south. Until now.
Recent analysis places another group of theropods, the megaraptora, under the tyrannosaur umbrella as tyrannosauroids. Though not very closely related to the more derived tyrannosaurs like Tyrannosaurus and Albertosaurus, they are still technically members of the family as a whole. This discovery extends the range of the tyrannosaurs much further than previously thought. Now it can be said they stalked the continents of South America and Australia, as well as the lands of the north. Also, given the similarity between species found in the south, I would not be surprised if any megaraptorids are also discovered in Africa.
Not only does this extend the range of tyrannosaurs to the south, but it brings giants like Siats and deadly killers like Australovenator into the tyrannosaur family.
The reign of the tyrannosaurs was truly global...
More primitive tyrannosauroids like Megaraptor hunted in the south...
While more derived species like Daspletosaurus terrorized the north...
Some form or a Rex walked on Australia...? 0_0 Thanks for informing me...
Hooray for Australia!

Rex fan! Good to see you again man! Great post, really covered the expanse of the Tyrannosaurs' domain. Very informative for the less informed!

REX FAN 684 - Greetings! It is so very good to see you again! The information you have presented is exceptionally compelling! I had no idea that the Megaraptors were part of the Tyrannosaur family - how very neat! Thank you so very much for sharing this fascinating topic with us! Once again, it is very good to see you! :)

Cool post, it is cool to think how in the past many groups of animals migrated and lived all over. Interesting how early humans made it all over the globe, too.

Who placed the megaraptors in the tyrannosaurid umbrella? And I thought Siats was more acrocanthosaur/carchardontosaur?

As far as Siats goes, Zanno and Makovicky placed it in the megaraptora in 2013.

Nice list, i thought for years that Megaraptor and it's kind were Allosaurs, like Giganotosaurus and Carcharodontosaurus...... Nice to see Tyrannosaurus in south, but it might not be as Powerful as The Abelisaurid or Allosaurid of the South. but to be sure, how the hell did Tyrannosaurus gets to south america ?? are they theory's.

Keep in mind the megaraptora represent primitive tyrannosauroids and could have radiated south before Pangea seperated the whole way(island hopping and such).
And originally, Megaraptor was only known by the large claws. However, based on the discovery of a front limb and it's cousin Austrolavenator, scientists have been able to piece it together. Then, in 2014, they described a juvenile specimen...

Hm. Never knew Megaraptor was a tyrannosaur.
