Trying to remember the name of a game I used to play. It was somehwat three-dimensional. I remember you would start off in a museum, then you would go through exhibits and the exhibits would have you go into different prehistoric periods. You had a mission where the exhibit would turn into a grassland with dinosaurs from that period and you would have to search an entire island to find the dinosaur type in a certain amount of time, and you'd have to evade predator dinosaurs. One very specific thing I remember, which is the biggest clue, was the exhibit was kind of like a maze, and if you went down the wrong hallway there would be a 2-d velociraptor in it. It wouldn't like run after you or anything but if you ran into it you'd have tos tart over.
