FACT SHEET: iguanodon NAME: IGUANODON (ee-GUAN-oh-don), meaning: “Iguana Tooth” SIZE: 30 feet long, 16 feet tall at the hips (the size of a bus), weighed 5 tons TYPE OF DIET: Herbivore (leaves from cycads) WHEN: Late Jurassic period (135 - 125 million years ago) WHERE: Belgium, England, Germany (Europe), North America, North Africa Iguanodon fossils are some of the first dinosaur bones ever found. A tooth and a few bones were found by a British scientist named Gideon Mantell in the 1820s. These first fossils looked like the teeth of a modern iguana. That is how Iguanodon got its name, which means “iguana tooth”. Iguanodon lived about 135 to 125 million years ago. The Iguanodon was a very successful dinosaur; the species survived for a long time. Iguanodon bones have been found in many places. Iguanodon spread and lived in every continent except Antarctica. It was a big herbivore, meaning that it ate only plants. It grew to be about 30 feet long and 16 feet tall. That is about the size of a school bus. It spent most of its time on all fours, but could run on two legs when it needed to move quickly. It was a relatively fast dinosaur. It could rear up onto its two back legs in order to escape from predators, and it could use its hands to gather food. Iguanodon had a flat, stiff tail, which stuck straight out behind it for balance. It had no front teeth, just a horn-covered beak which it used to rip the leaves off tough plants. In the back of its mouth it had rows of grinding teeth packed closely together. We believe that Iguanodon traveled in large groups. We know this because about 30 Iguanodon skeletons were found together in a coal mine in Belgium, in Northern Europe. Among them were bones of adults and younger dinosaurs.

v^ Official Journal of the Biology Unit of the American Topical Association 10 Vol. 40(4) DINOSAURS ON STAMPS by Michael K. Brett-Surman Ph.D. Dinosaurs are the most popular animals of all time, and the most misunderstood. Dinosaurs did not fly in the air and did not live in the oceans, nor on lake bottoms. Not all large "prehistoric monsters" are dinosaurs. The most famous NON-dinosaurs are plesiosaurs, moso- saurs, pelycosaurs, pterodactyls and ichthyosaurs. Any name ending in 'saurus' is not automatically a dinosaur, for' example, Mastodonto- saurus is neither a mastodon nor a dinosaur - it is an amphibian! Dinosaurs are defined by a combination of skeletal features that cannot readily be seen when the animal is fully restored in a flesh reconstruction. Because of the confusion, this compilation is offered as a checklist for the collector. This topical list compiles all the dinosaurs on stamps where the actual bones are pictured or whole restorations are used. It excludes footprints (as used in the Lesotho stamps), cartoons (as in the 1984 issue from Gambia), silhouettes (Ascension Island # 305) and unoffi- cial issues such as the famous Sinclair Dinosaur stamps. The name "Brontosaurus", which appears on many stamps, is used with quotation marks to denote it as a popular name in contrast to its correct scientific name, Apatosaurus. For those interested in a detailed encyclopedic work about all fossils on stamps, the reader is referred to the forthcoming book, 'Paleontology - a Guide to the Postal Materials Depicting Prehistoric Lifeforms' by Fran Adams et. al. The best book currently in print is a book titled 'Dinosaur Stamps of the World' by Baldwin & Halstead.

A Revised Taxonomy of the Iguanodont Dinosaur Genera and Species
ARTICLE IN PRESS + MODEL Cretaceous Research xx (2007) 1e25 www.elsevier.com/locate/CretRes A revised taxonomy of the iguanodont dinosaur genera and species Gregory S. Paul 3109 North Calvert Station, Side Apartment, Baltimore, MD 21218-3807, USA Received 20 April 2006; accepted in revised form 27 April 2007 Abstract Criteria for designating dinosaur genera are inconsistent; some very similar species are highly split at the generic level, other anatomically disparate species are united at the same rank. Since the mid-1800s the classic genus Iguanodon has become a taxonomic grab-bag containing species spanning most of the Early Cretaceous of the northern hemisphere. Recently the genus was radically redesignated when the type was shifted from nondiagnostic English Valanginian teeth to a complete skull and skeleton of the heavily built, semi-quadrupedal I. bernissartensis from much younger Belgian sediments, even though the latter is very different in form from the gracile skeletal remains described by Mantell. Currently, iguanodont remains from Europe are usually assigned to either robust I. bernissartensis or gracile I. atherﬁeldensis, regardless of lo- cation or stage. A stratigraphic analysis is combined with a character census that shows the European iguanodonts are markedly more morpho- logically divergent than other dinosaur genera, and some appear phylogenetically more derived than others. Two new genera and a new species have been or are named for the gracile iguanodonts of the Wealden Supergroup; strongly bipedal Mantellisaurus atherﬁeldensis Paul (2006. Turning the old into the new: a separate genus for the gracile iguanodont from the Wealden of England. In: Carpenter, K. (Ed.), Horns and Beaks: Ceratopsian and Ornithopod Dinosaurs.

Jahrb. d. kgl. ungar. Geolog. Reichsanst. XXIII. Bd. 1 heft I. Introduction. Since it appears doubtful when my monographic description of the dinosaurs of Transylvania1 that formed my so-to-speak preparatory works to my current dinosaur studies can be completed, due on one hand to outside circumstances, but on the other hand to the new arrangement of the vertebrate material in the kgl. ungar. geologischen Reichsanstalt accomplished by Dr. KORMOS, the necessity emerged of also exhibiting some of the dinosaur material located here, so that L. v. LÓCZY left the revision to me; I view the occasion, already briefly anticipating my final work at this point, to give diagnoses of the dinosaurs from the Transylvanian Cretaceous known up to now made possible from a systematic division of the current material, as well as to discuss their biology. The reptile remains known from the Danian of Transylvania will be mentioned only incidentally. Concerning the literature, I believe in refraining from more exact citations, since this work presents only a preliminary note.

DINOSAUR BOOKLET No. 2 Iguanodon Bernissartensis and Mantellisaurus Atherfieldensis
DINOSAUR BOOKLET No. 2 Iguanodon bernissartensis and Mantellisaurus atherfieldensis Description Iguanodon (pronounced 'Ig-wan-oh-don') was one of the first dinosaurs to be named. The name is derived from 'Iguana' - a type of modern reptile, and 'don' meaning tooth. Iguanodon is the name of a small group of dinosaurs within the much larger group called Iguanodontids; they were large herbivores, with a long tail for balance, and hind legs that were longer than their fore limbs. There were three large hooved toes on each foot, and four fingers and a thumb spike on each hand. The mouth had a battery of chewing teeth, and a boney beak in place of front teeth. Since its initial discovery in the early nineteenth century, and more detailed reconstructions after complete skeletons were found in a Belgian mine in 1878, we have been forced to re-evaluate its posture, shape and movement; and to look again at how it fits in with other members of the Iguanodontids. Fossil remains from the group show they existed from the late Jurassic through to the late Cretaceous. Here on the Isle of Wight it was once thought there were two basic species of Iguanodon; a larger form called Iguanodon bernissartensis, and a more graceful species called Iguanodon atherfieldensis. The first was named after the Belgian town where complete skeletons were found (Bernissart) and the latter from Atherfield on the south west coast of the Isle of Wight. However 1 more recently palaeontologist Gregory Paul has moved our smaller variety to a new genera, leaving us with only one Iguanodon but a new genera of Iguanodontid called Mantellisaurus atherfieldensis (named after Gideon Mantell) in its place.

At the advent of dinosaur paleontology fossil hunters like Gideon Mantell discovered some of the first dinosaurs like Iguanodon and Megalosaurus. Through new disciples like Georges Cuvier’s comparative anatomy lead early dinosaur paleontologist to reconstruct them like giant reptiles of absurd proportions. This lead to the formation of a new paradigm that prehistoric animals like dinosaurs existed and eventually went extinct.
