Not to be confused with Amargasaurus

Agustinia was a huge sauropod of the Early Cretaceous. Agustinia is a bizarre dinosaur whose remains have been found in South America. It had large spikes upon its back of an unknown purpose.

Classification Edit

Classification: Sauropoda, Somphospondyli, Agustiniidae

Species: A. ligabuei

Synonyms: Augustia

Characteristics Edit

Agustinia lived in the woodlands of the area which is currently known as South America.

As far as the armor is concerned, some paleontologists who have studied the fossil remains say that what appeared to be armors were actually fragments of hips and ribs. If those paleontologists are correct then, Agustinia didn’t have any armored plates.

However, it is assumed that the dinosaur did have armored plates on its neck and back and that the plates were arranged in such a way that they appeared to be thin when looked from side but full size appeared only when looked at from the front.

Agustinia was actually named as Augustia in 1998. However, when it was found that Augustia had already been used for naming another creature, the name was changed to Agustinia.

Another interesting one of Agustinia facts is that though the fossil was discovered by Agustin Martinelli, paleontologist Jose F. Bonaparte was the person who was actually responsible for identification of the dinosaur.

Discovery Edit

The fossil was discovered in Argentina by Agustin Martinelli before 1998.

Size Edit

Length: Unknown

Behaviour Edit

Unknown, although Agustinia may have lived in herds for protection.
