The large penguin, as reconstructed by Canterbury Museum

The stays of a large penguin the scale of a human have been found in New Zealand.

The fossilised bones are of an animal thought to have been about 1.6m (5ft 3in) tall, weighing as much as 80kg (176lb).

It lived within the Paleocene Epoch, between 66 and 56 million years in the past.

The animal, dubbed “monster penguin” by Canterbury Museum, provides to the record of now-extinct gigantic New Zealand fauna. Parrots, eagles, burrowing bats and the moa, a 3.6m-tall hen, additionally characteristic.

Why was the penguin gigantic?

“This is likely one of the largest penguin species ever discovered,” Paul Scofield, the museum’s senior curator, advised the BBC. It was particular to the waters of the Southern Hemisphere, he added.

Penguins are thought to have change into this huge as a result of massive marine reptiles disappeared from the oceans, across the identical time that dinosaurs disappeared.

“Then, for 30 million years, it was the time of the enormous penguins,” Mr Scofield stated.

At this time’s largest species, the Emperor Penguin, grows to about 1.2m tall.

“We predict that on the time, animals had been evolving very quickly,” Mr Scofield defined. “Water temperatures round New Zealand had been splendid again then, round 25C (77F) in comparison with the 8C we have now now.”

It is a small little bit of bone – however a sizeable discovery

In the course of the time of the enormous penguin, New Zealand was nonetheless joined with Australia, which in flip is believed to have been linked to Antarctica.

The brand new species, crossvallia waiparensis, resembles one other prehistoric large penguin, crossvallia unienwillia, which was discovered at a website in Antarctica.

In keeping with the researchers, the crossvallia penguin’s toes most likely performed an even bigger position in swimming than these of contemporary penguins.

It seemingly shared the waters round New Zealand with “large turtles, corals and strange-looking sharks,” Mr Scofield says.

Why is not it round anymore?

It is not fully clear why the enormous penguins disappeared from the waters of the Southern Hemisphere.

Probably the most generally held concept is that it is merely as a consequence of rising competitors with marine mammals.

“On the time large penguins developed, the massive marine reptiles simply had change into extinct,” Gerald Mayr, one other creator of the brand new research, advised the BBC.

“In Antarctica and New Zealand, there have been no massive marine opponents till the arrival of toothed whales and pinnipeds (seals) many million years later.”

The extinction of the enormous penguins appears to correlate with the rise of those opponents, however the precise causes for the disappearance of large penguins are nonetheless being mentioned, Mr Mayr cautions.

The place was it discovered?

The leg bones of the brand new species had been found at a website in North Canterbury final 12 months and have since been analysed by a world staff.

“This website is just about distinctive,” Mr Scofield stated. “It is a river mattress chopping right into a cliff.”

The place has been the positioning of fossil finds for the reason that 1980s, and most of the discoveries – like this newest one – are made by devoted novice palaeontologists.
