On this episode, we talk about:

Identify means “big southern lizard”
Carolinii title got here from Ruben Carolini, an novice fossil hunter who discovered Giganotosaurus within the Rio Limay Formation of Patagonia in 1993
First described within the journal Nature, by paleontologists Rodolfo Coria and Leonardo Salgado in 1995 (considered the biggest carnivorous dinosaur on the time)

Giganotosaurus was discovered close to Villa el Chocon, which now has a Giganotosaurus statue beside the street
First skeleton discovered was 70% full, and included the cranium, pelvis, leg bones and many of the spine (was 6.5 tons, 13 toes tall at hip, 40-41 toes lengthy)
A second Giganotosaurus skeleton was estimated to be 8% larger (43 toes lengthy and eight tons)

Giganotosaurus about 100 to 90 million years in the past, throughout the mid Cretaceous time
It had a small mind for its measurement (measurement of a banana), however had a very good sense of scent
Cranium was about 6 toes lengthy

Giganotosaurus had sharp, 8-inch tooth with serrated edges, three-fingered “arms” and two quick arms, and a skinny, pointed tail
Additionally was bipedal, with highly effective legs that would transfer as much as 31 mph; might flip shortly whereas operating
Could have hunted titanosaurids, like Argentinosaurus; different titanosaurs discovered close to Giganotosaurus have been Andesaurus and Limaysaurus

Wouldn’t have been capable of tackle an grownup alone; could have hunted in packs to take down giant prey
Used its tooth to slice by means of prey (widespread to its household carcharodontosaurids); bones of Argentinosaurus have been too giant to crunch with tooth, so Giganotosaurus would have needed to chunk on softer tissue, raking throughout the flesh
Then it might look ahead to the Argentinosaurus to lose blood of be contaminated and die (could have focused leg muscular tissues to sever a tendon and cripple the titanosaur)

Seven skeletons of Mapusaurus, an in depth cousin that seemed related, the place present in the identical space as Giganotosaurus (means they died close to one another, however raises the chance that they lived in a group)
Giganotosaurus rescued the protagonists in James Gureny’s Dinotopia from a T-rex
Giganotosaurus can be within the fifth Land Earlier than Time film, and within the 2008 film Journey to the Heart of the Earth

Carcharodontosaurids means “shark-toothed lizards” they usually have been a bunch of carnivorous theropods
Ernst Stromer named the Carcharodontosauridae household in 1931
Some Carcharodontosaurids embrace Giganotosaurus, Mapusaurus, Carcharodontosaurus, and Tyrannotitan, which have been all related in measurement or barely larger than T-rex

In 2006, when Mapusaurus was found, Rodolfo Coria and Phil Currie named a subfamily of Carcharodontosauridae, referred to as Giganotosaurinae, for essentially the most superior species from South America (which have been extra carefully associated than those from Africa and Europe)
Enjoyable truth: 99% of all species are extinct (10-14 million are round at present)
