Dreadnoughtus schrani

Scientists have studied the bones of a dinosaur discovered in Argentina’s Patagonia region. The dinosaur species has been given the name Dreadnoughtus schrani. It is the largest, biggest, and most gigantic land animal ever found (whose mass has been calculable). Over 70% of its bones were found, which ranks pretty high for a dinosaur of this size.

The dinosaur is estimated to have been 85 feet (26 m) long with a weight of 65 tons (about 60,000 kg). That’s about a dozen African elephants! It falls into a group of dinosaurs called titanosaurs. The dinosaur had a long neck and tail, and roamed on our planet approximately 77 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). 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.

Here are videos about the dinosaur and about how to fossilize yourself.
