Dino Days

From BoardGameGeek:

Fill your week of dinosaurs, scoring the most points in the process. Each dinosaur has unique rules of play, some cancel scores, some swap dinos, other special cards affect game play like the diplodocus where you need two cards to play and the giganotosaurus which each player starts with that can wipe out an entire opponent's board, but gives them 10 points. One deck is needed per two people playing. -description from the designer
