![]() Lordkipanidze and his coauthors suggest that, taken together, these skulls demonstrate how the Dmanisi humans varied in appearance from one individual to the next. Those individuals may not have actually lived alongside each other, but apparently occupied this same place within a window of a few thousand years more than 1.75 million years ago. At least five relatively complete skulls have been found there in the last two decades. The newly described skull isn't the only one that has been found at Dmanisi. This combination of features has fueled a long-running discussion over whether the Dmanisi humans were an early form of Homo erectus, a distinct species called Homo georgicus, or something else. The skull's face, large teeth, and small brain size resemble those of earlier fossil humans, but the detailed anatomy of its braincase-which gives clues to the wiring of the brain-is similar to that of a more recent early human species called Homo erectus. That is because Skull 5 is what paleoanthropologists often refer to as a "mosaic," or mixture of features seen in earlier and later humans. ![]() He adds that the fossil's importance was clear as soon as the team saw it, but required eight years of preparatory analysis. "It was discovered on August 5, 2005-in fact, on my birthday," Lordkipanidze says. The cranium turned up five years later, at the fossil-rich Dmanisi site 96 miles southwest of Tbilisi, and is now being reported in the journal Science. Researchers, led by Georgian National Museum anthropologist David Lordkipanidze, first found the complete lower jaw of a fossil human in 2000. The survival of the individuals with such ailments is indicative of group support and care, which allowed their injuries to heal.Please be respectful of copyright. In addition to Cro-Magnon 1’s fungal infection, several of the individuals found at the shelter had fused vertebrae in their necks indicating traumatic injury, and the adult female found at the shelter had survived for some time with a skull fracture. A large brow ridge no longer tops the eye sockets and there is no prominent prognathism of the face and jaw.Īnalysis of the skeletons found at the rock shelter indicates that the humans of this time period led a physically tough life. However, the skull of Cro-Magnon 1 does show traits that are unique to modern humans, including the tall, rounded skull with a near vertical forehead. While the Cro-Magnon remains are representative of the earliest anatomically modern human beings to appear in Western Europe, this population was not the earliest anatomically modern humans to evolve - our species evolved about 200,000 years ago in Africa. Except for the teeth, his skull is complete, though the bones in his face are noticeably pitted from a fungal infection. Scientists estimate his age at death at less than 50 years old. Associated tools and fragments of fossil animal bone date the site to the uppermost Pleistocene, probably between 32,000 and 30,000 years old.Ĭro-Magnon 1 is a middle-aged, male skeleton of one of the four adults found in the cave at Cro-Magnon. The site was one of the first to establish the ancient roots of modern humans, and fossils from this shelter represent some of the oldest Homo sapiens populations of Europe. The condition and placement of ornaments, including pieces of shell and animal teeth fashioned into what appear to be pendants or necklaces, led researchers to believe the skeletons had been intentionally buried within the shelter in a single grave. The occupation area revealed the remains of four adult skeletons, one infant, and some fragmentary bones. Researchers recognized an occupation floor toward the back of the cave during excavations. Road construction in 1868 revealed the rock shelter tucked into a limestone cliff. ![]() This famous fossil skull is from one of several modern human skeletons found at the famous rock shelter site at Cro-Magnon, near the village of Les Eyzies, France.
