ISLAMABAD-New Zealand’s monster penguins that lived 62 million years ago had doppelgangers in Japan, the USA and Canada, a study published today in the Journal of Zoological Systematics and Evolutionary Research has found. Scientists have identified striking similarities between the penguins’ fossilized bones and those of a group of much younger Northern Hemisphere birds, the plotopterids. These similarities suggest plotopterids and ancient penguins looked very similar and might help scientists understand how birds started using their wings to swim instead of fly. Around 62 million years ago, the earliest known penguins swam in tropical seas that almost submerged the land that is now New Zealand. Paleontologists have found the fossilized bones of these ancient waddlers at Waipara, North Canterbury. They have identified nine different species, ranging in size from small penguins, the size of today’s Yellow-Eyed Penguin, to 1.6 meter-high monsters.
