Aptenodytes ridgeni, also referred to as Ridgen's penguin, is an extinct species of penguin from the Pliocene of New Zealand.^[1] It was intermediate in size between its living congeners, standing an estimated 90–100 cm tall. The remains were first found in 1968 on a Canterbury region beach by 11-year-old schoolboy Alan Ridgen.^[2]
