Massive Dreadnoughtus And Alien-Like Spinosaurus The Latest Dinosaurs To Create Waves

Though dinosaur finds are revealed on a fairly regular basis, very few result in as much excitement as the latest two. On Thursday, September 4th, a team of scientists led by Kenneth Lacovara, an associate professor at Philadelphia's Drexel University unveiled the Dreadnoughtus schrani, which they believe is the biggest known land animal to have ever inhabited Earth. While dinosaur fans were still digesting the facts, on September 11th, came news of the re-discovery of the Spinosaurus aegyptiacus, the only known semi-aquatic dinosaur.
