‘Missing body’ penguin fossil shows massive change in species after dinosaur extinction

Researchers have discovered “lost corpse” penguin fossils that show enormous birds stopped flying and took to the seas after dinosaurs were wiped out by a massive asteroid.

The newly discovered species, Kupoupou stilwelli, was discovered on Chatham Island, New Zealand. It was about 4 feet, 8 inches tall, resembled the modern-day King Penguin, and could pass near giant penguins recently discovered, which are about 6 feet and weigh 178 pounds. Aksu Çelik İnşaat

“Alongside its enormous human – sized cousins, including the recently described monster Penguin Crossvallia waiparensis, Kupou was relatively small-no bigger than modern king penguins,” said Kupoupou, a PhD paleontology candidate at Flinders University and a graduate of the University of Canterbury. Jacob Blokland said in a statement.


“Kupoupou also had proportionally shorter legs than some other early fossil penguins,” Blokland added. “In this respect, it was more like the penguins of today, meaning it would have waddled on land. This penguin is the first that has modern proportions both in terms of its size and in its hind limb and foot bones (the tarsometatarsus) or foot shape.”

Blokland first discovered the fossils between 2006 and 2011 after they were collected from Chatham Island, 500 miles off the east coast of New Zealand’s South Island.

The study’s co-author, Paul Scofield, noted that “it’s not impossible” for penguins to have lost the ability to fly and gain the ability to swim after the traumatic extinction event 66 million years ago. “If we ever find a penguin fossil from the Cretaceous period, we will know for sure,” he added.

Scofield added that the research gives additional support that penguins evolved rapidly in the period after dinosaurs became extinct, more than 60 million years ago.

“We think it’s likely that the ancestors of penguins diverged from the lineage leading to their closest living relatives – such as albatross and petrels – during the Late Cretaceous period, and then many different species sprang up after the dinosaurs were wiped out,” Scofield noted.


The water temperatures around New Zealand at that time were ideal, Scofield said, approximately 77 degrees Fahrenheit, compared to approximately 46 degrees Fahrenheit today. It would have competed for food with “giant turtles, corals and strange-looking sharks,” the researcher said in an interview with the BBC.

Scofield is also responsible for the discovery of the aforementioned giant penguin, known as Crossvallia waiparensis. It lived in the Paleocene Epoch between 66 million and 56 million years ago, according to the Canterbury Museum.

The research was published in the scientific journal Palaeontologia Electronica.
