Australia.  We studied the cause of megaphone extinction

Recent research published in the Papers in Paleontology sheds new light on the extinction of species. Geniornis. Giant birds were known to disappear suddenly from our planet, but there is no evidence to suggest why.

At the same time, about 40,000 years ago, many other large animals died in Australia. At a similar time, these areas were inhabited by humans, so some scientists believed that our species was responsible for their extinction.

At the end of the nineteenth century, several fossils of some of the largest birds in the world were found in the vicinity. Jessiora Calabona. At one point, individuals were trapped in the mud that ended their lives. However, it turns out that this is not their main concern.

These creatures had a high rate of bone disease. All kinds of chambers and deformities cause pain to the animals and significantly limit their mobility. As a result, it is very difficult to find enough food and water around a drying lake. It should be noted that it is similar to the emu species that live today Geniornis He could not fly, which would definitely help him in such a situation.

The drought phase began about 48,000 years ago. Later, the entire reservoir lost water and remains in this condition to this day. Until the end, the birds tried to absorb small amounts of life-giving fluid. By the end of this period, the majority of the population was extinct. It is not known how long individuals survived and whether they lived.

Of course, an example Jessiora Calabona It maps events taking place across the continent. Many reservoirs and forests have been depleted, and the amount of all kinds of goods has been significantly reduced. Larger creatures that need them the most, and, as a result of the long-term stress caused by this condition, began to suffer from various diseases.
