As for the feathered animals, Pachystruthio dmanisensis is a monster. With an approximate mass of about 450 kilograms (almost half a ton), this would make a 150-pound adult ostrich, the largest living bird in the world, looking like a canary.
Larger birds existed but not as large as the size of this non-flying bird, but the unexpected location of its remains were found on the northern Black Sea coast.
The Crimean peninsula in the summer of 2018 proved to be a fan of paleontologists.
Among picking, including bones of mammoths, cats, hyenas, horses, and even a small wolf, there was a rather strange femur.
Paleontologist of the Russian Academy of Sciences Nikita Zelenkov initially assumed that the petrified bone of the foot with its impressive weight had to come from a Madagascarian elephant bird.
Animals of unusual size ̵
The femur itself is roughly the expected bird-elephant, but with a slightly thinner look, suggesting it is a runner. the proportions of the bones set its height at about 3.5 meters (11.5 feet), which means that we can imagine P. dmanisensis either as a tall, thin elephant bird or as a rather ostrich.
"We still do not have enough data to tell if it is most closely related to ostriches or other birds, but we thought they weighed." That huge weight is almost twice as large as the largest moa, three times the largest living bird, the common ostriches, and almost as much as an adult polar bear. "
The crown of the greatest Aves class member goes to a vanished species of an elephant bird called Vorombe titan on the African island of Madagascar before disappearing about a thousand years ago.
With a huge 860 pounds (1895 pounds), it would also
Examining the mix of animals found in the cave, the researchers estimate that they would have been laid for resting about 1.5 to 2 million years ago
Homo erectus Bones found to the east of the Black Sea are dated to roughly the same period, making it more than likely that the relatives of our ancestors not only share the territory of the bird but may have hunted it.
With people in their queues, not to mention predators, including cats, wolves and hyenas, it is not surprising that P.
Finding a giant bird on the European continent helps us understand better only the species of fauna that people may have encountered as they migrate through the landscape but also the environment itself.
The rule could explain the size of some large, non-flying birds, but to explain why the egg and ostriches are so high, the researchers turn to the Jarman-Bell principle.
When it becomes difficult, animals turn to difficult foods. And when it comes to squeezing everything you can from a bunch of low-fat, fibrous meals, larger bodies offer greater benefits.
R. dmanisensis We can imagine a dry landscape at the edge of the open steppe, where ancient humans and long tooth predators are looking for fast and easy feeding in a huge chicken.
Whether people have a hand in his disappearance is too difficult to say at this stage. We hope this will not be the last bone we will ever find on this massive bird.
