Welcome to the Cretaceous. Our ancestors won’t climb down from the trees for another 66 million years, but here we are now. Time travel seemed like a good idea. Exploring the ancient world. Building. Creating an entire society here in the jungles of our primordial Earth. Until those SATI guys messed it all up.

This book includes:

• A complete, ready-to-play science-fiction game world for the Cypher System, with a detailed history, scores of fascinating locations, new gear and technologies, and a variety of factions and conflicts to drive your story.
  
• More than 20 new creatures and NPC types, from the snuggly nerezza to the unpredictable lab-grown supersauri. Encounter teslasaurs, cyberdrones, and genetically engineered spiders, plus dinosaurs of all descriptions.
  
• New character types and abilities. Be a Volcanic Karn who Self-Evolves, an Empirical Tec who Plays God, or perhaps a Daring Pteryx Who Walks with Dinosaurs.
  
• Rules for dinosaur companions. Choose a ceratopsian, pterosaur, early mammal, ornithomimid—even a raptor or tyrannosaur. You’ll want the help and companionship as you explore the dangerous wilds of Cretaceous Grevakc!
