Overview: Almost a century ago, paleontologists found the first tantalizing hints of a monster even bigger than Tyrannosaurus Rex, perhaps the largest predator ever to walk the Earth: spectacular fossil bones from a dinosaur dubbed Spinosaurus. But the fossils were completely destroyed during a World War II Allied bombing raid, leaving only drawings, lots of questions, and a mystery: What was Spinosaurus?

DVD Verdict: First discovered in 1912 by German aristocrat Ernst Stromer, the dinosaur called Spinosaurus was believed to be a meat eater even larger than Tyrannosaurus rex. Unfortunately for Stromer and the science of palaeontology, the world's only Spinosaurus skeleton was destroyed in World War II leaving behind many secrets.

Modern day palaeontologist Nizar Ibrahim receives word that an amateur Moroccan fossil hunter has unearthed a new Spinosaurus skeleton so he travels to Morocco, along with a team of scientists that includes Paul Sereno, in order to verify these claims and find more Spinosaurus bones.

Upon finding the fossil hunter who found the additional Spinosaurs material, Inbrahim's team are taken to the site of the excavation where they find yet more Spinosaurus bones. Upon studying the newly discovered skeleton, the team realize that they are looking at one of the weirdest dinosaurs ever found. The newly reconstructed Spinosaurus turns out to be the first aquatic dinosaur to be the first aquatic dinosaur to be discovered by science.

'NOVA: Bigger Than T. Rex' follows the paleontologists who are reconstructing this terrifying carnivore piece by piece, revealing a 53-foot-long behemoth with a huge dorsal sail, enormous, scimitar-like claws, and massive superjaws hosting an army of teeth. It is a painstaking puzzle, and it is missing many of its pieces.

Bringing together experts in paleontology, geology, climatology, and paleobotany, this NOVA/National Geographic special brings to life the lost world over which Spinosaurus reigned more than 65 million years ago. This is a Widescreen Presentation (1.85:1) enhanced for 16x9 TVs.
