"Extreme Dinosaurs" is an interesting BBC documentary about palaeontologists who through pain-staking detective work try to solve some mysteries surrounding Argentinosaurus and Giganotosaurus, two virtual monsters unearthed in Patagonia.
Frankly, it's almost unbelievable that a creature the size of Argentinosaurus could even have existed! The riddle scientists want to solve is whether this huge animal (a peaceful herbivore) had any natural enemies. The carnivorous Giganotosaurus (which was the size of a T-Rex) was nevertheless too small to take on a fully grown Argentinosaurus. One possibility is that Giganotosaurus was a pack hunter, but this is a controversial idea. Tyrannosaurus and similar dinosaurs are generally thought of as solitary animals.
The scientists featured in the documentary believe they have found tantalizing evidence that overturns the standard view. The fossilized remains of what might be a Tyrannosaurus pack have been unearthed in a remote region of Canada. More to the point, a newly discovered unnamed relative of Giganotosaurus in Patagonia might have lived in packs, too. Thus, a true "battle of the titans" between the super-sized Argentinosaurus and packs of marauding carnosaurs might actually have taken place... It seems even dinos need a dino-burger from time to time!
I admit that I really don't care whether or not Argentino and Giganoto fought the battle of the millennium, but some people seem childishly fascinated by such a prospect. Too much video games? I was more intrigued by the amount of research (and good luck) that went into this project. One of the palaeontologists managed to find the sensational Canadian site with the help of a century-old photo in National Geographic. Sherlock Holmes would have been impressed.
Overall, I think this was a relatively good documentary, so I give it four stars.
