Nationalgeographic.co.id—When early humans first arrived in Europe, they probably coexisted with bird the largest creature that walks on Earth is a creature like bird camel with and weight 453 kg and height 3.3 meters.
Quoted from News Week, bird bird ancient giants have been thought to have lived only on the distant mainland of Madagascar, New Zealand, and Australia.
The largest known species is bird elephants, which lived towards the end of the Quaternary period (about 2.5 million to 11,700 years ago). This creature is estimated to have a body mass of up to 680 kilograms. As a comparison, bird an ordinary camel weighs about 136 kg.
“Bird fossils of impressive giant size have never been documented from Europe or the Northern Hemisphere in general,” scientists from the Russian Academy of Sciences noted in a paper published in Journal of Vertebrate Palaeontology.
However, excavations in the Taurida Caves on the Crimean Peninsula led to the discovery of the species bird Very large. This species is not new. It has previously been identified from fossils found at sites in Eastern Europe. But until now it was unclear when he lived or whether early humans would come into contact with him.
Scientists say bird that, named Pachystruthio dmanisensis, probably a creature that can’t fly. His femur, which is long and thin, indicates that he is a fast runner. After analyzing the bones, the team said it was heavy Pachystruthio almost on par with polar bears.

Pachystruthio found along with ancient bison bones and other fossils, allowing scientists to date them to between 1.5 and two million years ago. This is comparable to the age of a nearby archaeological site that is thought to be the earliest evidence of hominins outside Africa.
As a result, researchers believe these large birds would have been part of the landscape by the time our ancestors arrived. “These large birds may have been a source of meat, bone, feathers, and eggshells for early hominin populations,” the scientists wrote.

Nikita Zelenkov, lead author of the study, said there was no evidence of further interactions with early humans, but that any type of them must have existed. He thought that Pachystruthio is a harmless animal. It’s just that the ability to run is most likely indeed to avoid predators.
Moreover, other animals that lived in the area at the same time as Pachystruthio included the giant cheetah, giant hyena, and saber-toothed cat. His ability to run is likely the key to his survival.
They currently don’t know which species of bird they are most closely related to Pachystruthio. Excavations are continuing at the cave site where it was found. Zelenkov hopes to dig up more bones to better understand the species.
