Scientists have discovered a new dinosaur from Argentina with powerful claws, feasting on an ancient crocodile bone. The new find was possibly 23 feet (7 meters) long and hailed from a mysterious group of dinosaurs called megaraptorans. They prowled across what’s now South America, Australia and parts of Asia, splitting off into different species over millions of years. Ibiricu named the new dinosaur in memory of his son Joaquin. While Joaquin was very young and hadn't yet developed a fascination with dinosaurs, Ibiricu still thinks he would have appreciated being named after one.
