WASHINGTON (AP) — A study proclaims a newly named species the heavyweight champion of all dinosaurs.
The plant-eating giant is the largest of a group of dinosaurs called titanosaurs (tye-TAN’-u-sawr). At 76 tons (69 metric tons), the behemoth was as heavy as a space shuttle.
A scientific paper released Tuesday describes and dates the fossils found in southern Argentina in 2012. A skeleton of the dinosaur is already on display at the American Museum of Natural History in New York.
The researchers examined fossils of six creatures of the new species and dated them back about 100 million years. The giants measured about 122 feet long (37 meters) with shoulders 20 feet high (6 meters), dwarfing Tyrannosaurus rex.
Researchers named it Patagotitan mayorum, combining Patagonia and titan, along with a host family’s name.
