(Yes, this is a real animal name) This mod adds Dickinsonia to the game. To tame Dickinsonia, you need to kill one, harvest the Dickinsonia Slices with a sword and then put them underwater. It will hatch into a Dickinsonia (after 2 hours 45 minutes) that you can claim. They rarely spawn where Eurypterids are, in The Island and The Center, in most waters in Extinction,and an aberrant variant spawns in Aberration in most waters.
