Bones discovered in Argentina are being called the bones of the largest, biggest, and most gigantic animal known to have walked on our planet. The animal bones are of a dinosaur type called titanosaur. The dinosaur had an approximate length of 40 meters (about 130 feet, the length of two trucks) and weight of 80 tons (160,000 pounds – the weight of about 14 elephants). It had a long neck and tail, and roamed on Earth 95 million years ago.
Even if we were around at the time, this titanosaur would not have chomped us down as it was a vegetarian (a herbivore). Previously, the largest animal record was held by the argentinosaurus. Many scientists believe that about 65 million years ago, a type of rock from space known as an asteroid hit the Yucatan Peninsula in Mexico, and caused big climate changes which wiped out the dinosaurs.
It is believed that our planet came into existence around 4.5 billion years ago. The first living things (single-celled organisms) came into existence around 3.5 billion years ago. Dinosaurs came into existence around 240 million years ago, and they all died around 65 million years ago. Humans came into existence just 0.2 million years ago.
