ARK: Survival Evolved Companion
These are soooooooo valuable, you may not need them right away when first playing the game, but kill them and collect everything they drop anyways. Kill them when you dont need them, because eventually, you will, and if you dont, you'll regret it later. I go whole days trilobite hunting on my spino.
More Trilobite Utility Tips
These are tameable for Pc Users, all you need to learn is the Fish Basket engram and drop one down near a high lvl trilobite and then stand in the trilo’s way and guide it til it’s near your basket then capture it, release it before it expires in your inventory then cryopod it up for save keepings! Trick no ones sharing is you can hide blueprints in abberation trilobites and then hide them underwater ;) p.s you can also tame leeches and then leave them on aggro for biowarfare at obelisks or transmitters lol or Sabre salmon then catch release then cryo them for easier otter taming or attaching c4 to said salmon then attacking underwater targets....
