Argentinosaurus: The 120Ft Dinosaur Which Had A Long Neck Of About 29Ft And Weighed About 100,000Kg

Argentinosaurus which means "Argentine lizard" was a genus of giant Sauropod dinosaurs and a member of the Titanosauria group which existed during the late Cretaceous period.

Its first fossil bone was discovered by a farmer on his farm close to the city of Plaza Huincul in 1987, but the specimen was excavated in 1989 by a team led by Bonaparte a paleontologist who named it in 1993 alongside his colleague Rodolfo Coria.

How big were they

Argentinosaurus was believed to be among the biggest known land animals though it's actual size was not really determined due to incomplete fossils; but its size was estimated to be about 30-36.6 metres (98-120ft) and weighed up to 80-100 tonnes (80,000-100,000kg).

They had a tail of about 40 metres long and a neck of approximately 29ft long.

What did the feed on

Due to their fossils, argentinosaurus were believed to be plant eaters and ate only conifers and they were able to eat about 850kg of food daily.

Where did they live

They lived during the Cretaceous period and were found in South America.

Did they have predators

Argentinosaurus is believed to have had only one predator which was the Mapusaurus a large theropod that hunts big preys.

How did they protect themselves

Due to the absence of sharp teeths, Argentinosaurus had two ways of defending themselves from predators, which was either by lashing out its long tail or swinging its neck so as to drive away predators.

When did they go into extinction

Argentinosaurus went into extinction as a result of the mass extinction caused by an asteroid which hit Mexico during the Cretaceous period about 65 million years ago.
