Ekrixinatosaurus
Name:
Ekrixinatosaurus
(Explosion-born lizard).
Phonetic: Ek-riks-in-at-oh-sore-us.
Named By: Jorge Calvo, David Rubilar-Rogers
& Karen Moreno - 2004.
Classification: Chordata, Reptilia, Dinosauria,
Saurischia, Theropoda, Abelisauridae, Carnotaurinae.
Species: E. novasi (type).
Diet: Carnivore.
Size: Roughly about 10 meters long, however different comparison
methods to other abelisaurid dinosaurs yields either slightly smaller
or even slightly larger estimates.
Known locations: Argentina - Candeleros
Formation.
Time period: Cenomainan of the Cretaceous.
Fossil representation: Partial skull and post
cranial remains.
To date Ekrixinatosaurus is without doubt one of the largest abelisaurid theropods that we currently know about, and even at the lower estimate of ten meters long, Ekrixinatosaurus was still bigger than the far more famous Carnotaurus which at the time of writing seems to have had a maximum size of nine meters long. Because of the large size, Ekrixinatosaurus was probably a predator of other large dinosaur in its ecosystem such as the sauropods like Andesaurus. Despite the large size however, Ekrixinatosaurus was likely not the apex predator of its time and location as the even bigger carcharodontosaurid Giganotosaurus is also known from the same formation.
