Diamonds & Dinosaurs

From BoardGameGeek:

A group of competing adventurers take on a dinosaur filled jungle in search of the biggest diamonds you've ever seen. Get them fast and get out quick as dinosaurs move across an expanding map every turn. The map is built as players explore the island so no two games will play the same. Use your actions wisely and make use of items found throughout the jungle. Be the first to collect four of the massive gemstones and make it back to base camp for evacuation! Explore the jungle, gather diamonds, avoid dinosaurs, will you be the first one out? At the start of a players turn, they draw 2 map cards to expand the map and 1 item card as they search the jungle. Players get 3 actions on their turn. Actions may be used to either move or pick up diamonds. Movement requires a player to roll 2 dice which allows them to move to a space with a number equal to or lower the number they rolled. The spaces are cards that are laid out by the players every turn so the map will always be different. The first player who collects 4 diamonds and is able to get them back to base camp (the central starting card) is the winner. -description from the publisher
