def. Jurassic: 
1. A geologic period spanning from approximately 200 to 145 million years ago. 
2. A cool adjective to use in everyday life to describe something or someone ancient and/or gargantuan. For example, "My Jurassic professor doesn't even know how to use a computer. He does all of his lectures in chalk on the blackboard!" and, "Wow, this is a Jurassic portion of french fries! Please help me eat these."
3. A time period when the following dinosaurs were NOT alive: T-Rex,Velociraptors, and Triceratops, the dinosaur stars of the movie "Jurassic Park." Dinosaurs that WERE alive during the Jurassic period include Sauropods such as Apatosaurus and Brachiosaurus, Theropods such as Allosaurus and Megalosaurus, and --one of my favorite dinosaurs--Iguanodons.
