The Extinct Research Lab came in Extinct Animals. After you buy it you are able to find Fossils and create dinosaurs and other Extinct Animals in a minigame, if you fail you can create an ambient animal or Killer Penguins. You are also able to cure special diseases with a different minigame.
To begin, the player must purchase an Extinct Animal Research Lab, and then enter 'fossil finding mode'. The player must then find fossils using a hand held sonar device, which beeps when a fossil is nearby. Once the player has achieved the required number of bones, one must return to the Research Lab for the next step. The player can get upgrades for the sonar device as his star rating increases, which also unlocks the fossils of additional animals. The player must also dig up a majority of the bones, as paleontologists will sometimes abandon a dig site to continue searching for new ones. The player can jump to the dig site using the zoo map.
Then the hunter can enter the lab and put the fossils together like a jigsaw puzzle. Using the '<' and '>' keys, the player can rotate each piece of fossil to fit into the skeleton. Once completed, the player can then move on to the cloning stage.

This is then followed by the cloning stage, also within the Research Lab. This minigame is more similar to Marine Mania's trick training game. The player uses a scanner to analyze the DNA, while pressing the left mouse button and arrow keys. Once this is completed, the player can clone the animal in question for no price at any time, but must repeat the DNA minigame to do so.<ref name="YouTube">YouTube - Zoo Tycoon 2: Extinct Animals.

If the player gathers a low score in the minigame, an unlockable animal, usually a deformed version of an ambient animals, is given instead. Also during the DNA minigame, if a high-enough accuracy is achieved, a super animal will be created. The name of the animal will be 'Super' followed by the animal name and number. Super animals are slightly larger than their original size, get ill less often and instead of the regular circle around the animal when it is selected, a DNA symbol with a star surrounds the animal. By the gender of the animal in the animal's stats tab, a test tube symbol will signal a super animal. It is impossible to purchase super animals. However, if one breeds a super animal with either a normal or super animal, the offspring will occasionally be one. Very rarely, the offspring of two normal animals will be a super animal.
