I found at 20/34 small island.

Any updates on this?

confirmed

For anyone still looking for Deinonychus nests. So far we found them here:
- Island in the far north/east corner of the map (found 2 nests so far)
- On the mountain at ~35,52 between the ruins (found 1 nest so far)
- Island in the west at ~20,32 (found 2 nests so far)
- Small island in the east at ~55,81 (found 1 nest so far)

We also found Deinonychus here, but so far no nests:
- Island in the far north at ~10,60 (the biggest island in the cluster of three)
- Island south of redwoods at ~70,48
- Large island in the far south/east corner of the map at ~85,85

In addition: I recommend the immersive taming mod. Not only is it way better than the standard way of taming, it also allows for taming the wild Deins.
