, a horny beak, spikelike thumbs, and a powerful tail. It may have been capable of walking on either two or four feet. Fossils remains of the 30-ft-long (9-m) reptile have been found in Europe, Asia, Africa, and the W United States in strata of the early Cretaceous period, approximately 135–110 million years ago. It possessed characteristic spikelike thumbs. Iguanodon, the second dinosaur to be formally named, was first described by Gideon Mantell, an English physician and geologist. He credited his wife, Mary Ann Woodhouse Mantell, with the discovery. An impressive find by miners in a Belgian coal mine in 1878 turned up more than 20 nearly complete fossil skeletons.

Just as the film depicts the effects of a massive meteor shower on the Dinosaur population during the Cretaceous period, this ride places guests on "time rovers" which take them back to the very end of the Dinosaur era, there to rescue a young Iguanodon -- like the central character of Dinosaur -- before the meteor storm wipes out his kind, and perhaps our time rover as well.
Barbara Kerley became interested in Hawkins when she saw a picture of the iguanodon dinner party and was struck by Hawkins' unusual name.
Within the first ten pages of Chapter 1 alone, Barbara Black takes us to dinner in the belly of a thirty-five-foot-long model Iguanodon, entertains us with a twenty-four-piece orchestra in the literally named Whale-bone Lounge constructed within the skeleton of a vast whale, and invites us to explore the interior of James Wyld's massive model of the globe on a journey at once to the centre of the earth and to its farthest reaches.
Ironically, given that the author seems intrigued by images, the publisher did not allow for nearly enough illustrations--the omission of the Dinner in the Iguanodon being the most egregious.
