Argentinosaurus is perhaps the largest creature ever to have lived on dry land. Its immense size is almost certain to have protected it against even the larger predator dinosaurs. Only a few Argentinosaurus bones have been discovered, but these have been used to estimate its size. One of its spinal vertebrae alone was 1.6 m high!
Lenght: 35-40 m
Weight: 80-100 t
Age: Late Cretaceous (100-90 mio. years ago)
DID YOU KNOW…
that even though Argentinosaurus was enormous, its babies were not? In fact, they had to grow to around 25,000 times their hatchling size before they were fully grown!
