You can find these at herbivore Island around the edges in the water! Hit da cool button so people can get pearls!

Keep the pearls. You'll thank me later.

Sure does come in handy when these guys are around. They crawl out of the water every morning at the same time every day. Easy way to get black pearls and oil

On the left side of the island map, there is a bit that looks a bit like a crooked finger. First of all, you can wall off the part that connects it to the rest of the island and turn the entire finger into your base. It is extremely safe and the only predators there are ichthyornises and dilos. Second of all, at the part where it connects to the rest of the island, there is a small pond surrounded by rocks and in that pond a ton of trilobites spawn. I made my base on this finger and made a chitin farm with the pond. Do with this knowledge what you will.

Early morning they come out of the water onto the beach

I have recently discovered that these are by far the most valuable tame for any level of player.

Why you ask? Try taming 1 and then put anything at in it's inventory and see what happens ;) also you don't have to feed them AT ALL

Kill these on sight to get resources that you’ll need later because these suddenly disappear when you need them

Hey guys for those who are playing on the island at the bit u spawn on the trilobites spawn mostly at 12:00 hope this helps someone

I struggle to find silica pearls on the island so at one point in time I hunted these guys down to the brink of extinction. (I basically just slaughter them).
