Giant, human-sized penguins once roamed Earth, researchers say

Gerald Mayr/Senckenberg Research Institute(WASHINGTON) — Giant penguins, standing over 6 feet tall and weighing more than 220 pounds, may have roamed Earth some 60 million years ago, according to new research.

Scientists on Tuesday said they discovered fossils of an ancient penguin that may have stood 5-foot-7 — nearly the height of the average American male — at about 223 pounds, according to a Nature Communications research report.

The monster flightless bird, called the Kumimanu biceae, is believed to have swam off the coast of New Zealand between 56 million and 60 million years ago, according to the research.

The size would dwarf the emperor penguin, the biggest penguin today, which stands at less than 4 feet tall.

Researchers said the fossils, unearthed in New Zealand, shed “considerable light on the early evolution of penguins.”

“Kumimanu shows that gigantism was not uncommon in early penguins, and was already in the earliest evolutionary stages of these birds,” said Gerald Mayr, a paleontologist at the Senckenberg Research Institute in Frankfurt, Germany, and lead author of the Nature Communications report.

He said the fossils are “among the oldest known finds of penguins and it is worth noting that already earliest forms were enormously large.”
