When it came to prehistoric school photo day, the Patagotitan would unequivocally have stood at the back. Thought to be the world’s largest terrestrial animal of all time, this giant would have been nine times heavier than an African elephant. To give you an idea of its size, the Patagotitan’s thigh bones alone were 2.4 metres tall.

Fortunately for smaller animals, this absolute unit wasn’t directly a threat (unless you got caught under its big feet). In the forested regions of Patagonia, roughly 100 million to 95 million years ago, the Patagotitan munched on leaves from coniferous trees.

When fossils of the species were found in the Cerro Barcino Formation in 2014, it was simply known as the Titanosaur until its formal naming in 2017.
