Tyrannotitan Chubutensis

a very poorly known theropod..

Tyrannotitan is a huge Carcharodontosaurid of the early Cretaceous period, discovered in Argentina. It is closely related to other giant predators like Giganotosaurus and Mapusaurus,Its fearsome appearance is reflected in the meaning of its name, "Tyrant titan".

The bones that could confirm its star status and immense size - around 13 meters and 6 tons - are still buried under Argentinan dirt.this is all we have, but despite this, we can take a guess on what Tyrannotitan looked and perhaps behaved like, based on its enormous relatives.  it's more 'basal' then other Carcharodontosaurs, and oddly enough had teeth closer to the Tyrannosaurs then Carcharodontosaurs. In fact, Tyrannotitan  seems to show an evolution towards a more Tyrannosaurid like appearence in Carcharodontosaurs. So little is known about Tyrannotitan, only guesses can be made to what its Paleobiology was. my best guess is It coexisted with the other large Carcharodontosaur Giganotosaurus, the Spinosaur Oxalaia,as well as the massive abelisaur Ekrixinosaurus. Massive competition drove the Carcharodontosaurs, and Tyrannotitan in particular, to immense size. These enormous theropods most likely fed on the massive sauropod Argentinosaurus, along with any thing else they could take out.
