The reference guide connects fossil collection with DNA and dinosaur eggs: complete fossil sets are brought to Dr. Ivy’s DNA Lab. This makes collection progress the key step before hatching.

A guide page checked on 2026-10-12 reports different set sizes by collection: Cambrian and Devonian entries use five fossils each, while Triassic and later island entries use three in the recorded table. Confirm the requirement shown for your chosen creature before making another trip.
