In Mass Effect 3, gathering war assets and completing side quests is essential for building the strongest possible force against the Reapers. Among these secondary objectives is finding the Kakliosaur Fossil for a salarian scientist on the Citadel. Understanding where to locate this artifact and when the mission becomes available ensures Commander Shepard can secure valuable krogan war assets without missing crucial campaign deadlines.

Unlocking the Citadel Kakliosaur Fossil Mission

To initiate the quest, players must head to the Presidium Commons area on the Citadel. Near the apartments, a salarian scientist explains that a kakliosaur specimen could assist krogan troops in surviving hostile environments. Overhearing or speaking directly to the scientist adds the Citadel: Kakliosaur Fossil entry to your mission log.

Prerequisite Story Progression and System Unlocks

Although you can obtain the quest early in Act 3, the cluster containing the fossil remains locked for a portion of the game. Players must progress through the main storyline and complete Priority: Perseus Veil followed by Priority: Geth Dreadnought. Finishing these primary story beats unlocks the Argos Rho cluster on the Galaxy Map, allowing Commander Shepard to begin the search.

Finding the Kakliosaur Fossil Location

Once Argos Rho is accessible, pilot the Normandy to the Intai'sei system within that cluster. Scan the planet Intai'sei to pinpoint the exact location of the fossilized specimen on the surface. Launch a probe to retrieve the item, which will then safely store the artifact in your inventory.

Completing the Quest and Claiming Rewards

After acquiring the artifact, return to the Citadel Presidium Commons and hand it over to the salarian scientist. Completing this exchange rewards Shepard with experience points, credits, and an update to your War Assets under the Krogan alliance tab. Finalizing these collection quests before point-of-no-return story events ensures maximum readiness for the endgame.
