Trilobites

Trilobites appeared in the console version of the video game Night at the Museum: Battle of the Smithsonian, as a part of both the main game and as well as an extra mini-game in the menu.
== Overview ==
=== Night at the Museum: Battle of the Smithsonian (Video Game) ===
==== Wii/PC/Xbox 360 ====
Trilobites appear in the National Museum of Natural History level in the Night at the Museum: Battle of the Smithsonian video game, where they distract an Allosaurus skeleton named Ally, until they crawl into an air grate. To get past the dinosaur, Larry must use his key chain to open the grate and release the trilobites so the can continue distracting the Allosaurus. Before the fight against Al Capone, they continue to distract Ally as they enter the rotunda until Larry tames her with the Tablet of Ahkmenrah's animal ingot.
Trilobites are also featured in a puzzle mini-game in the same level (located on the wall on the right side of the entrance to Cleopatra's room) as part of a side quest, also activated with the animal ingot. The goal of the game is to use the flashlight to lead each colored trilobite (red, yellow, green, and blue) to its original place on the wall. They can only move forward and can pass over other holes (including their own if not facing the same direction), but can't pass over other trilobites.
Once a trilobite reaches its spot facing the same direction, it will be embedded into the wall and allow other trilobites to pass over. If a pair of trilobites end up getting stuck facing each other, the player will have to restart (which they can do at any time) and try again. The mini-game and side quest will be completed once all the trilobites return to their places on the wall and complete the puzzle. 
The player can also get the Fossil Fuel achievement for solving the puzzle and play more Trilobite Game configurations from the Mini Games Menu.
=== History ===
Trilobites are extinct marine arthropods that form the class Trilobita. Trilobites form one of the earliest known groups of arthropods. The first appearance of trilobites in the fossil record defines the base of the Atdabanian stage of the Early Cambrian period (521 million years ago) and they flourished throughout the lower Paleozoic before slipping into a long decline, when, during the Devonian, all trilobite orders except the Proetida died out. The last extant trilobites finally disappeared in the mass extinction at the end of the Permian about 251.9 million years ago. Trilobites were among the most successful of all early animals, existing in oceans for almost 270 million years, with over 22,000 species having been described.
