This book really boils my blood. Don Lessem claims "the King is dead" (refering to T .rex)just because Giganotosaurus is a little bit bigger. He forgot to include how T .rex has a much bigger brain, longer and stronger legs, WAY more powerful jaws, teeth and neck. Not to mention the advantage of Steroscopic vision and lots of other advantages T .rex had. He is trying to make Giganotosaurus what it isn't. This book is HIGHLY biased and is NOT recommended for serious reading. The pictures looked like Giganotosaurus was on steriods (over inflated chest). Giganotosaurus was an interesting animal, but all the hype and false claims is really damaging it's popularity. This book doesn't cover much info on this south american titan and leaves a lot to be desired.

We are all being deceived, as Giginotosaurus is NOT the biggest known carnivorous dinosaur ever found. Its skull was purposefully extended to make it look larger than T-Rex, but in fact it was not. And even if the skull is larger than Sue's (the largest and most complete T-Rex), there has been a new discovery of a T-Rex nearly 60 fet long, eclipsing Gigy by almost 20 feet. But all in all, it makes for a good reference for dinoartists and lovers of all kind.
