Many species of Iguanodon were named in the 1800s in North America, Asia, North Africa and eastern Europe, but these have since been reassigned to new genera, leaving those found in western Europe in the UK, Spain and Belgium, as the only valid Iguanodon species. It was only after over thirty complete skeletons were found in a Belgian mine that the dinosaur's true shape was revealed.
Pteranodontids had a distinctive, elongated crest jutting from the rear of the head (most famously seen in Pteranodon itself). The family was named in 1876 by Othniel Charles Marsh. The first few fossils of Iguanodon were found in southern England and were rather scattered, the thumb spike was originally believed to be a horn. The Pteranodontidae are a family of large pterosaurs of the Cretaceous Period of North America and Africa. Iguanodon was one of the first dinosaurs to be formally discovered and thus named, making it a historically significant animal. Although smaller than most of the Hadrosaurs ingame, Iguanodon is still a decently large animal. While they weren’t birds either, they exhibited many of the same behaviors as well as some unique traits of their own. They lived during the Late Cretaceous alongside well-known dinosaurs, including the Tyrannosaurus rex. In Prehistoric Kingdom, Iguanodon's defensive capabilities are bolstered by a long string of thick osteoderms across its back and sides. Pteranodon longiceps was one of the largest winged reptiles and weren’t actually dinosaurs at all.
As so often happens with such early discoveries, subsequent paleontologists assigned numerous individual species to each of these genera, with the result that the taxonomies of Pterodactylus and Pteranodon are as tangled as a birds nest. It was a relative of Centrosaurus and Monoclonius. Iguanodon's forelimbs were notably stiff, owing to their use as weapons and as a method of locomotion, but also featured a flexible, grasping finger, functioning similar to a thumb. Pterodactylus was unearthed way back in 1784, and Pteranodon in the mid-19th century. Styracosaurus ( meaning 'spiked lizard') was an herbivorous dinosaur from the Cretaceous period.

This large, late Cretaceous pterosaur attained wingspans of close to 20 feet, though its 'wings' were made of skin rather than feathers its other vaguely birdlike characteristics included (possibly) webbed feet and a toothless beak. More then capable of fighting back, Iguanodon was known to use its spikes in combat, as well as its impressive size and weight.

Still, if there's one specific pterosaur that folks have in mind when they say 'pterodactyl,' it's Pteranodon. Iguanodon is a large and bulky ornithopod famously known for its large thumb spikes on each forelimb.
