98-million-year-old ichthyosaur fossil in New Zealand challenges ideas on marine reptile evolution.

A rare 98-million-year-old ichthyosaur fossil discovered in New Zealand is providing new insights into these ancient dolphin-like creatures. This nearly complete skeleton, one of the youngest and most intact of its kind, suggests that ichthyosaurs in New Zealand were distinct from those in South America. The find challenges earlier ideas about the evolutionary connections between southern hemisphere marine reptiles and indicates a more regional distribution of ichthyosaurs during the Late Cretaceous period.
