The close relative of the Emperor Penguins lived in NZ about 3 million years ago: What is the reason for their death?

Three million years ago, today’s great penguins, an outrageous relative of today’s great penguins living in Authero New Zealand.

We know this because our new research has been published in Journal of Pilotology Explains a wonderful foam skull of a great penguin found on the coast of Tranaki.

Overall, it is 31 % longer than the skull of an Emperor Penguin (epithenoids forestry), which can be more than meter long and can weigh more than 35kg.

However, compared to the Emperor Penguins, however, the great penguin had a very strong and long lime. It probably looked like a king penguin (epitheniditis pategonic), which was only huge.

At that time, the world was hot more than today. But when the climate was cool, the penguin disappeared.

We argue that the cold was not accused because Crushed and Little Penguins in New Zealand fought the same change and remained. Great Penguins moved to the south and today live in the frozen waste of Antarctica. So what did their ancient relatives suffer from an end?

The sesame seeds that now form the huts towards the beach in southern Tarnaki were deposited at a time when the global temperature was already more than 3 ° C in the industrial period. For a long time, the focus has been changing our understanding of how gewyota can respond to the growing temperature.

For example, there was a house of fish and monk seals in Autirova, both of which still (all) are tropical. In a strange contradiction, he combined with the great penguins in ancient New Zealand, which only found in the more cold climate.

The colonialism of the northern genocide of King Penguins is around 46.1 ° S in the suburbatic crocodile islands today, where seawater temperatures reach 3-10 ° C. From there, it only cools towards the highest levels where the Emperor Penguins live.

Three million years ago, the Great Penguins of Otiroa extended to 40.5 ° S north, where southern Taranaki was located. The relatives of their relatives, which were 20 ° C in the water, were much hoter than today’s experience.

The upper existence ended with a plason icy period about 2.5 2.58 million years ago. When the temperature fluctuates and eventually moves down, the snow range and surface surfaces go back and forth. But why will such a cooling be eliminated?

Giant air hunter

The evidence for the giant penguins in Autarwa is limited and the exact reasons for his death are unclear. Nevertheless, their sheer presence suggests that they were less compulsory because of the more levels of temperature. Another method should be in the game.

Until about 500 500 years ago, Autarova was a hunting field for the Dev Hast Eagle and a huge Forbes Herrier. They were a big repair. Among them, big birds like MOA were in their diet. His ancestors came from Australia in the last three million years.

Based on what we see with the living great penguins, Tranaki’s great penguin certainly created large exposed colonies along the coast. These could have been the simplest goals for a giant eagle or herrer hunting from the air.

On the contrary, even today, the small penguins found in Autarwa are more secretive breeding. They nest the bills, natural spares and dense plants and cross the beaches at night, which can help them avoid air hunters.

Earth predictions are just one assumption, though, to help explain why these penguins disappeared in the region while others survived. Other possibilities include changes to the maritime environment.

We know that less food availability can be destructive to penguins, but it is difficult to see why it will compete with penguins.

The important thing is that our study provides new insights about tolerance for great penguins. King and Emperor Penguins can compare temperatures up to 20 ° C nowadays than they usually fodder.

Three million years ago, his relative experienced such warmth. As the world is hot, we need to remember that the geographical limit of any kind can change as the situation changes.

The Ottirova’s Economic System will go to the residential zone of many new species, which will be more important than ever.
