This sourcebook contains information about dinosaurs and other prehistoric animals for role-playing games. This information can be used for dinosaurs and other prehistoric animals cloned by mad scientists, encountered by time travelers, surviving in lost worlds or as monsters in fantasy worlds.

Playing Dinosaurs

This sourcebook can also be used for games where players control creatures like the informal "playing dinosaurs" games that kids play with dinosaurs toys and by LARPing (Live-Action Role Playing.) The prehistoric settings in this book list creatures who probably lived in the same area at the same time (with a few exceptions.) The settings and creatures chosen emphasize famous prehistoric creatures featured in toys, movies and popular books.

Dinosaurs and Prehistoric Animals can be played as a board game, simulation, strategy game, collectible card game, or using miniatures. To play The Dinosaur Game as a simulation or strategy game, choose a setting and a creature from that setting for each player to control. Decide what the players' goals are: Fighting for territory? Stalking prey? Escaping? To balance the game some players can control more than one creature of the same species.

To play the game as a collectible toy and card game, each player controls a creature corresponding to a toy, card or picture of a dinosaur or other prehistoric animal from any manufacturer or publisher, (including yourself!) The creatures don't have to be from the same setting. Players can control more than one creature if it is necessary to balance the game, but if possible the player should have a separate picture or toy for each individual creature. One player can control creatures of more than one type.

Scenarios

Permian Period

Before the dinosaurs, giant synapsid reptiles walked the Earth. These synapsids are more closely related to mammals than to dinosaurs. Dimetrodon and Edaphosaurus were pelycosaurs that looked like giant lizards with tall sails on their backs. The therapsids looked more like mammals, with short tails and powerful front legs. The armored pareiasaurs also grew large in the Permian period. They were anapsid reptiles, possibly related to turtles. Other Permian reptiles, including the ancestors of the dinosaurs, did not grow as large.

Triassic Period

The Archosaurs and the First Dinosaurs

The Triassic is the first period of the Mesozoic era. The Triassic introduces the giant sea reptiles, such as plesiosaurs and ichthyosaurs, and the first pterosaurs and dinosaurs. However, the landscape is still ruled by archosaurs combining dinosaur and crocodile-like features such as Postosuchus and the armored Aetosaurs. Beaked mammal-like plant-eating dicynodonts such as Lystrosaurus and Placerias were thick on the ground throughout the Triassic.

Jurassic Period

Giant Dinosaurs and Sea Monsters

The Jurassic is the middle and perhaps most iconic period of the Mesozoic era. Huge theropod dinosaurs like Allosaurus preyed on even more gigantic sauropod dinosaurs like Diploducus and better armored dinosaurs like Stegosaurus. In the sea pliosaurs such as Liopleurodon preyed on Ichthyosaurus and plesiosaurs like Cryptoclidus.

Early Cretaceous Period

Rise of the "Raptors"

Late Cretaceous Period

Tyrannosaurs and Sea Serpents

The late Cretaceous of North America is the most iconic scenario of the Cretaceous (only lacking sauropods and Stegosaurus.) Mosasaurs (sea serpents) replace pliosaurs in the late Cretaceous seas. Birds are the only dinosaurs to survive beyond the end of the Cretaceous. (The giant sea reptiles, pterosaurs and many other types of land and sea creatures went extinct at that time.)

Eocene Epoch

The Eocene epoch is the middle epoch of the Paleogene period - the beginning of the "Age of Mammals" but also a time when the giant flightless birds preyed on those mammals. Whales, including the mammalian "sea serpent" Basilosaurus, and the the first penguins first appear in the very warm Eocene epoch.

Miocene Epoch

The Miocene is the first epoch of the Neogene period. Cooler temperatures encouraged animals to grow larger. Australia and South America developed animals unlike anything alive today including new types of predatory marsupials and giant predatory birds.

Pleistocene

This recent cold period is sometimes called the Ice Age. Modern animals lived in most parts of the world, and many creatures moved back and forth between the contents of Africa, Europe, Asia, North and South America. Isolated Australia continued to have a unique fauna that included giant predatory birds and reptiles.
