West zone one waters have them in mobile mostly in the stream that ties to the ocean

When I was on like level 20 in single player i used to find these guys everywhere, and i thought they were only useful for a handful of chitin. Now I’m on level 88 and i actually NEED black and silicia pearls and oil I haven’t seen one in months.

Kill on site they give chitin oil and pearls when you need them they disappear

Use a hatchet or megatherium to harvest for max silica pearls and oil. Gives about a stack of chitin with a primitive metal hatchet and loads with the mega.

Beware I brought a Rex to fight it but my rex died in deep water

All you need is a spear or pike and you have a good source of silica pearls,black pearls,and chitin st low levels.

Fun fact: The trilobites appeared during the Cambrian explosion and was one of the most successful lifeforms on the planet. Nature had to try and wipe them out about 3 times and it took the most deadly mass extinction in the history of our planet to wipe them all out. The Permian Extinction also known as "The Great Dying"

get a shell cracking weapon and kill the thing and just a hint don’t get rid of the loot
