I found one on extinction but no gigas and 1 carcha, I’m on day 86

Anyone had any luck finding these in single player extinction? I've ran a dino wipe and using a dino finder mod and still unable to find one. Not sure how long it takes for one to spawn

I have seen it on island! Down from 50/50 there was like 6 there around that little pond oasis.

Yes you can find them on the Island. I found one while trudging through the swamps of all places.

The rhyniognatha can pick it up for the pvp people.

Has anyone found one on the island yet? I'm hoping to get one of these absolute units so that I can do more effective meat runs.
