''Nanosaur'' is a third person shooter developed by Creator/PangeaSoftware and released for the UsefulNotes/AppleMacintosh in 1998. In Nanosaur, you play a genetically engineered velociraptor from the the year 4122 sent to the Cretaceous Period to retrieve the eggs of five dinosaur species to save the Nanosaur species in the future. You only have twenty minutes to complete your mission before the asteroid hits Earth. During the mission, your Nanosaur will have to blast its way through several dinosaurs while collecting weapons and powerups.

A modified version, titled ''Nanosaur: Extreme!'' was released in 2002 for the Macintosh and Windows PC. This version is exactly the same as the regular version, except more dinosaurs appear at a time as well as more powerups available.

A sequel was released in 2004 titled ''Nanosaur II: Hatchling''. In this game, it is assumed that the first Nanosaur completed its mission successfully and returned to the future. But a group of rebel Nanosaurs stole the eggs and took them to distant planets, where they intend to use them to build an army to fight their battles against Earth. But one egg was left behind, which turns out to be a pterodactyl. This pterodactyl is sent on a mission to retrieve the stolen eggs and return them safely to Earth. The basic concept of ''Nanosaur II'' is similar to that of the first installment, in terms of collecting eggs and powerups, except that it contains three levels that take place on different planets, and you must kill hostile dinosaurs as well as turrets and other future defenses.

!! Nanosaur contains examples of:

* AllThereInTheManual: The human race is extinct in 4122.
* ArtisticLicensePaleontology:
** ''Stegosaurus'' did not live during the Cretaceous Period, they lived during the Jurassic.
** ''Dilophosaurus'' also lived in the Jurassic (only even earlier than ''Stegosaurus''), and it did not have a frill or spit venom like in ''Franchise/JurassicPark''.
* TheCretaceousIsAlwaysDoomed: You were sent back twenty minutes before the asteroid hits.
* DeflectorShields: One of the powerups.
* DumbDinos: All of the dinosaurs besides the player character fall under this trope - they neither notice nor care that you're trying to help. Doubly [[JustifiedTrope Justified]] by the fact that the player is both an ''intelligent'' dinosaur whereas the ones encountered are just savage animals, ''and'' a ''raptor'' who came to take their eggs.
* EverythingTryingToKillYou: If you thought dinosaurs were bad enough, you also have lava-balls, spore-shooting fungi, and rolling boulders to worry about!
* EverythingsBetterWithDinosaurs
* GottaCatchThemAll: The point of the first game is to gather one of each of the five types of eggs.
* {{Handguns}}: The Nanosaur's weapon, which has five different attacks: [[FrickinLaserBeams standard laser]], [[HomingProjectile heat-seeking missiles]] (which can lead to a MacrossMissileMassacre if the player has plenty to spare), [[MakeMeWannaShout sonics]], [[SpreadShot a dividing shot]], and [[NukeEm nuclear weapons]].
* JetPack: The Nanosaur has one.
* LethalLavaLand: The second environment after the green rainforest zone.
* MadeOfExplodium: Dinosaurs, apparently. (Though they actually "shatter" when they die.)
* NinjaPirateZombieRobot
** You are a raptor, armed with a jetpack and a laser cannon.
** Or a pterosaur, with a jetpack, various weapons, and a [[MakeMeWannaShout sonic scream]].
* RaptorAttack:
** Inspection of the game files will reveal a skeleton called "Deinon.skeleton", which hints that the Nanosaur is meant to be a ''[[http://en.wikipedia.org/wiki/Deinonychus Deinonychus]]'' and not the usual ''Velociraptor''. However, the Nanosaur model doesn't even have the sickle claws on its feet, making it look more like a miniature ''Allosaurus''.
** The ''Velociraptor'' from the sequel are Film/{{JurassicPark}}-styled as usual, with feathers on their heads.
* StockDinosaurs:
** You are a ''Deinonychus'', and you fight ''TyrannosaurusRex'', ''Stegosaurus'', ''Pteranodon'', ''Triceratops'', and ''Dilophosaurus''.
** The sequel has you playing as a pterosaur (resembling a toothed ''Pteranodon''), and the enemies are ''Brachiosaurus'', ''Velociraptors'', and ''Rhamphorhynchus''.
* TyrannosaurusRex: These like to pounce on you.
