Agustinia

Agustinia is a genus of sauropod dinosaur that lived in South America during the Early Cretaceous period, about 116 to 100 million years ago.

It is known from a single species, Agustinia ligabuei, which was named after the student who discovered the fossil and the philanthropist who funded the expedition.

Agustinia is notable for its unusual and distinctive osteoderms, which are bony plates or spikes that cover the skin.

These osteoderms were initially thought to form a series of vertical plates and spines along the back of the animal, similar to the unrelated Stegosaurus.

However, later studies suggested that these osteoderms were actually fragments of ribs and hip bones, and that Agustinia did not have any armor at all.

Agustinia was a large herbivorous dinosaur, estimated to be about 15 meters (49 feet) long.

It had a long neck and tail, and four pillar-like legs.

It belonged to the group of sauropods called titanosaurs, which were the most diverse and widespread group of sauropods in the Cretaceous.

However, Agustinia is poorly known and does not have many distinctive features that can separate it from other sauropods.

Because of this, some researchers have considered Agustinia to be a dubious name that cannot be reliably identified.
