>>> when dinosaurs ruled the architect, the tyrannosaurus rex was roaming the earth.y not have been the biggest beast. this is by far the largest species of dinosaur. >> there's money advantages to being big. it helps them avoid predators. predators don't attack you if you're that big. >> the pat a gortaten reached 120 feet from head to tail and weighed in at 72 tons, about as much as ten african elephants. a fossil was first it is in patagonia, argentina. part of its name was named after the land on which it was developed and the skeleton has been in the natural history of museum last year. ite so big the head can't fit into the museum. >> it was not done fully growingle weer not sure how much bigger they would have gotten. still. this is not the full-size. >> large and in charge right there. >> i love the name titanosaur. >> the interesting thing, t-rex and this one did not live at the same time. >> speaking of big, they scale the highest skyscrapers in search of high paychecks. a picture perfect way to tell story. your local news is next. for the rest of you stick
