Sauropod dinosaur - titanosaur

Argentinosaurus size

Argentinosaurus is one of the largest land animals ever discovered. ScaleCheck uses a 35 m, 70-tonne reconstruction to make its enormous but incomplete fossil record visible.

Argentinosaurus beside a 1.7 m human

The shared ground plane keeps 35 m and the human reference on one metre scale. Detailed models load progressively; labeled wireframes preserve scale where a model is pending.

Human scale

What 35 metres feels like

Its length spans about 20.6 reference-human heights - or a little more than three 11 m city buses placed nose to tail.

More than one number

Length, height and body mass

The dinosaur may be a little longer than the 33 m blue whale shown here, yet the whale's water-supported body carries far more mass.

Evidence boundary

How certain is this size?

Only fragmentary vertebrae, ribs and limb material are known. Body proportions and especially mass vary between reconstructions, so the displayed values are a reasoned midpoint, not a tape measurement.

Why compare it

The question this animal answers

Argentinosaurus turns the phrase 'largest land animal' into a physical constraint: four pillar-like limbs supported a body that would outweigh hundreds of people.
