"Standing with its neck up, it was about 20m high - equal to a seven-storey building"

Based on its huge thigh bones, it was 40m (130ft) long and 20m (65ft) tall.

Weighing in at 77 tonnes, it was as heavy as 14 African elephants, and seven tonnes heavier than the previous record holder, Argentinosaurus.

Scientists believe it is a new species of titanosaur – an enormous herbivore dating from the Late Cretaceous period.
