Scientists have revealed the world’s first ever complete T-rex skeleton – found after it fell to its death in a deadly duel with a triceratops. Each of the 67-million-year-old remains are among the best ever found and have only been seen by a select few people since they were discovered in 2006.

Can dinosaurs come back?

Without access to dinosaur DNA, researchers can’t clone true dinosaurs.

What was the lifespan of a dinosaur?

Early estimates of 300-year lifespans for the largest sauropods were based on comparisons with crocodiles and turtles, which have much slower metabolisms. The consensus is now that Apatosaurus and Diplodocus dinosaurs probably only lived for 70 or 80 years, which is about the same as an elephant today.
