On The Island, Trilobites sometimes spawn in the shallower part of the bay near South 1, the default spawn point.

Moschops can harvest both types of pearls in decent amounts and unreasonable amounts of chitin from these guys, along with a fair bit of oil. If youre planning to kill one of these guys, harvest it with a moschops.

I have a spawning point on the beach of these next to my house and I have like 9784 chitin from these guys and loads of black pearls plus other items it drops

You will find these in waterbed

Best source of oil for beginners and noobs

Kill on sight they are found near south one near the little strip of land. Hit with ax

I find them near 'the footpaw' on the Island.

Having a 180 Megatherium with 450 melee will give you 600-1100 chitin Per Trilobite.Tried myself

When I go hunting for these I have a low level wyvern and I walk down the shollow area of the water looking down and when I see one I use the breath weapon and bite then it’s normally dead

Me and my friend in survival evolved killed these guys a lot. Btw we didn't kill them for fun we did it for resources

If u need Pearl's harvest with a chainsaw

I have never seen this guy or the troodon since my playthrough... and im lvl 70...WHERE THE HELL ARE THEY?

Someone said bottom left if this is true they can be found at Craigs

And if you need chitin, tame baryonyx mount it and go to cave

On crystal isles a good place to find them, is on the outskirts of the island furthest southwest.

Where are they i hant seen one in ages

They spawn near the edge of the Arctic

You can find them on the beaches of carno island

You can find them around rivers

Or in the water of the rivers

These guys are in mobile its true i saw one on south zone 1 beach while i was going to get my rockcarrot farm .-. -hawk
