Crested Hadrosaurs

Fathom · 2019-07-18 22:35:16

Some hadrosaurs crested (Lambeosaurinae). Others (Hadrosaurinae) not. Crests had nasal passages. Underwater snorkel? Air reservoir? Adaptive advantage? Hide underwater? Crested also webbed feet? Not crested with camel feet? Crested more aquatic than not crested? Missing link? Evolved from crested water to not crested land?
