giganotosaurus

Seeing everyone make their  Pokemon variations I just wanted to make some of my own so bad! So I jumped on the Bandwagon with the mighty Tyrantrum!

Had the idea of making it into a few iconic theropods (even though a few of these aren’t too related lol).
Before you ask, I didn’t make Spinosaurus because it strays farther away from Tyrantrum’s design than what I preferred. The only reason I didn’t make Allosaurus was because of time constraints).

Carcharodontosaurus and other closely related species like Giganotosaurus  belong to the carcharodontid family because their sharp serrated teeth resemble sharks’ teeth. You can see how similar their skulls are even though they were found on two different continents.

Giganotosaurus reconstructions by James GurneyRodrigo Vega and Alain Bénéteau.

About Giganotosaurus being able to run, I quote James Gurney:

“This painting was done over ten years ago. Since then, John Hutchinson of Stanford University has convincingly argued that giant dinosaurs like T.rex or Giganotosaurus probably didn’t have the leg muscles to be able to run at the kind of speeds we imagine.

So if I were to do this painting again, I’d show him at a fast walk. A walking dinosaur may not be quite as impressive as a running dinosaur, but as long as he’s walking faster than his prey, it’s fast enough.”

NameGiganotosaurus carolinii 

Name Meaning: Carolinii’s Giant Southern Lizard 

First Described: 1995

Described By: Coria & Salgado 

ClassificationDinosauria, Saurischia, Theropoda, Neotheropoda, Averostra, Tetanurae, Orionides, Avetheropoda, Carnosauria, Allosauroidea, Allosauria, Carcharodontosauria, Carcharodontosauridae, Giganotosaurini 

Giganotosaurus is a rather famous, huge predatory dinosaur from the Candeleros Formation in Argentina. It lived in the Cenomanian stage of the Late Cretaceous, about 100 to 97 million years ago. It was 12 to 13 meters long and 4 meters high, and could have been even bigger than this. It was originally famous for being a theropod bigger than T. rex, however since this has become less of a special thing. Still, don’t underestimate this predator, since it was huge. However its relative lack of specimens (unlike T. rex) make understanding its growth patterns quite hard.

It had a very large skull, about 1.6 meters long. It was slender and elongate (so nothing like the skull of T. rex,) and with wrinkled patches on the snout tip and above the eye. The back of the skull is inclined so that the jaw joints far behind the attachment point of the neck. It had a larger brain than its close cousin Carcharodontosaurus, indicating it might have had somewhat better cognitive abilities than its cousin (assuming brain-to-body ratio is a good estimate of such things, which is of course up for debate.) It had short and thick shoulder blades, and the largest specimen known probably weighed between 6.5 and 13.8 tonnes.

Once again, feathered until proven otherwise. It lived near remains of titanosaurs Andesaurus and Limaysaurus, making it possible that Giganotosaurus hunted such large sauropods. It also lived near its cousin Mapusaurus, which has been found to hunt in packs (possibly), making it possible that Giganotosaurus did so as well (as depicted in the documentary Chased by Dinosaurus.) It has been estimated to have a top sprinting speed of 50 km/h, and wouldn’t have been able to balance well at speeds above that. However, given the size of this animal, 50 km/h is nothing to sneeze at.

It had a biting force three times less than that of T. rex, and instead was built for slicing prey, which would have allowed it to slash against soft tissue and the animal would wait for blood loss or infection to kill off the prey. It was probably one of the top predators in its ecosystem, preying not only on titanosaurs but also iguanodonts and other ornithischians, and competing against the abelisaurid Ekrixinatosaurus. It also lived alongside the dromaeosaurid Buitreraptor, the alvarezsauird Alnashetri, and the coelurosaurian Bicentenaria
