From dig site to egg

Hold with your shovel at a dig site and release in the green segment. Continue collecting toward a full set; Dr. Ivy is the named conversion destination.

Why set completion matters

The official requirement is a full fossil set. A single loose fossil is not the documented egg route. Match your collection to the set requirement shown in-game instead of assuming a fixed number of parts.

More islands

The developer says bigger boats open new fossil islands. That supports boat progression as an exploration route, but not a species-by-island drop table.
