Maiasaura — "good mother lizard" — earned its name from Jack Horner's 1978 Montana dig at Egg Mountain, where the first evidence of dinosaur parental nest care was documented. That discovery upended the prevailing view of dinosaurs as instinct-driven reptiles indifferent to their young. Niue has issued dozens of these dinosaur-themed silver rounds under rotating monarchs; this piece simply catches the series mid-stride at the accession of Charles III following Elizabeth II's death in September 2022.
