Dinosaur Digs includes 20 new prehistoric animals to choose from, including mammoths, sabre-toothed cats, and dinosaurs, as well as prehistoric-themed items and buildings. In addition, new types of electrical fences to accommodate the huge animals and prehistoric foliage have been introduced. In contrast to the regular animals, dinosaurs hatch from an egg and you need to employ a scientist to care for them. You also need to build a special building for dinosaur capture. Like in previous game, more extinct animals, foliage and better care for dinosaurs can be researched. Each of the animals comes as an egg, whereby a scientist is required to care for the egg, as well as the dinosaur once it hatches.
