Four little dinosaurs are playing outside, but their mothers have warned them to watch out for the Gigantosaurus. Gigantosaurus is a Mesozoic spin on a Peter and the Wolf like tale full of great rhythm, rhyme, and patterning. Now in danger of becoming a landlubber, Jonny lives in Wales with his wife, Jane, and their daughters, Daisy and Rosie. This book doesn't have dinosaur poop in but does have lots of dinosaurs and beautiful illustrations throughout. There's also a fold out page and, to whet the appetites of knowledge seekers, there are snippets of information about the featured dinosaurs on the two final double spreads.

I appreciate the rhythm of the text but there are some boo-boos (but nothing that will really distract kids or puzzle a reader). Three cute dinosaurs and one ugly dinosaur subtly named Bonehead are warned by their parents to avoid the Gigantosaurus.The included little baby Ankylosaurus plush toy measures approx 10cm tall at it longest length and approx 16cm long from it's outstretched hands to the end of it's tail and so it's not a very big plush toy but it is cute and also resembles the star of the book (Bonehead) very well. Giganotosaurus was also slightly smaller than Spinosaurus, currently the record holder for the longest carnivorous dinosaur , although it may have been more solidly built than the larger animal. Like The Boy who Cried Wolf, the theme to the story shares the caution of even when a liar is telling the truth, they are unlikely to be believed.

Describes some of the biggest dinosaurs that ever lived including the Sauroposeidon, the Giganotosaurus, the Spinosaurus, the Sauropelta, the Seismosaurus, the Argentinosaurus, the Shantungosaurus, and the Torosaurus.The story was simple, with repetitions, but the expectations were nice and I liked that the book ended with a touch of humor. The artwork is wonderful and fun to look at and the dialogue itself is also fun as it is all in rhyme.
