So, yes, I’ve already written an OK song about giant penguins before, but this is a new and different thing. NPR is reporting on a Nature study about a 220-pound penguin that was something of a terrifying apex predator once the Cretaceous Period came to a close:
The bird waddled around off the east coast of New Zealand between 55 and 60 million years ago. And it was a giant as far as penguins go. The researchers estimate that it probably weighed about 220 pounds and was around 5 feet 10 inches tall.
“That’s about as tall as a medium-sized man,” says Gerald Mayr, a paleontologist at the Senckenberg Research Institute and Natural History Museum in Franfurt, Germany, and the lead author of the new study published today in Nature Communications. “This particular specimen is one of the largest known fossil penguins.”
The largest living penguin, on the other hand, the Emperor penguin, is a good bit shorter — around 4 feet.
The scientists have named the new species Kumimanu biceae, which means ‘monster bird’ in the Maori language. (Kumi is the name of a monster in Maori mythology and manu means bird.)
What this new species shows is that penguins evolved to be big very early in their evolution, says Ewan Fordyce, a paleontologist at the University of Otago, New Zealand, who wasn’t involved in the new study.
“It’s a few million years after the extinction of the dinosaurs,” says Fordyce. With the giant reptiles gone, it may have opened “new ecological opportunities” to birds like penguins, allowing them to break through “a glass ceiling of evolutionary size,” he says.
The oceans may also have allowed penguins to get so big.
“Giant penguins were occupying the seas about 20 million years before whales entered the oceans,” she says. No whales, no seals, no marine mammals.
