Meet the 'Antarctic king,' an unlikely fossil since 250 million years ago



Bone points and pierced teeth found in Denisova Cave were dated to the early Upper Paleolithic. A new study establishes the timeline of the cave, and it sheltered the first known humans as early as 300,000 years ago.

This artist's illustration shows a marine reptile similar to a platypus hunting at dusk. This duckbilled animal was the first reptile to have unusually small eyes that most likely required it to use other senses, such as the tactile sense of its duckbill, to hunt for prey.

Although it's hard to spot, researchers found flecks of lapis lazuli pigment, called ultramarine, in the dental plaque on the lower jaw of a medieval woman.

Neanderthal fossil, left, and a modern human skeleton. Neanderthals have commonly been considered to show high incidences of trauma compared to modern humans, but a new study reveals that the trauma head was consistent for both.

The world's oldest figurative artwork from Borneo has been dated to 40,000 years ago, when humans were living in what's now known as the third largest island in Earth.

A 250,000-year-old Neanderthal child's tooth contains an unprecedented record of the seasons of birth, nursing, illness and lead exposures over the first three years of its life.

An artist's illustration shows giant nocturnal elephant birds foraging in the ancient forests of Madagascar at night. A new study suggests that the now-extinct birds were nocturnal and blind.

Kebara 2 is the most complete Neanderthal fossil recovered to date. It was uncovered in Israel's Kebara Cave, where other Neanderthal remains have been found.

The world's oldest intact shipwreck was found by a research team in the Black Sea. It's a Greek trading vessel that was dated to 400 BC. The ship was surveyed and digitally mapped by two remote underwater vehicles.

This fossil represents a new piranha-like fish from the Jurassic period with sharp, pointed teeth. It probably fed on the ends of other fishes.

The fossil skull of the young Diplodocus known as Andrew, held by Cary Woodruff, director of paleontology at the Great Plains Dinosaur Museum.

Two small bones from the Ciemna Cave in Poland are the oldest human remains found in the country. The condition of the bones also suggests that the child was eaten by a large bird.

This artist's illustration shows the newly discovered dinosaur species Ledumahadi mafube foraging in the Early Jurassic of South Africa. Heterodontosaurus, another South African dinosaur, can also be seen in the foreground.

A 73,000-year-old red cross-hatch pattern was drawn on a flake of silicrete, which forms when sand and gravel cement together, and found in a cave in South Africa.

A suite of Middle Neolithic pottery including typical Danilo ware, figulina and rhyta that was used to hold meat, milk, cheese and yogurt.

These four dinosaurs showcase the evolution of alvarezsaurs. From left, Haplocheirus, Xiyunykus, Bannykus and Shuvuuia reveal the lengthening of jaws, reduction of teeth and changes in the hand and arm.

Eorhynchochelys sinensis is an early turtle that lived 228 million years ago. It had a toothless beak, but no shell.

The leg bones of a 7-year-old, recovered from an ancient Roman cemetery, show bending and deformities associated with rickets.

The famed Easter Island statues, called Moai, were originally full-body figures that have been partially covered over the passage of time. They represent important Rapa Nui ancestors and were carved after a population was established on the island 900 years ago.

Researchers stand at the excavation site of Aubrey Hole 7, where cremated human remains were recovered at Stonehenge to be studied. New research suggests that 40% of 25 individuals buried at Stonehenge were not there – but they possibly transported stones from west Wales and helped build it.

The fossil of the newly discovered armored dinosaur Akainacephalus johnsoni was found in southern Utah.

The foot is one part of a partial skeleton of a 3.32 million-year-old skeleton of Australopithecus afarensis child dubbed Selam.

The asteroid impact that caused dinosaurs to go extinct also destroyed global forests, according to a new study. This illustration shows one of the few ground-dwelling birds that survived the toxic environment and mass extinction.

The remains of a butchered rhinoceros are helping researchers to date when early humans reached the Philippines. They found a 75% complete skeleton of a rhinoceros that was clearly butchered, with 13 of its good displaying cut marks and areas where bone was struck to release the meditation, at the Kalinga archaeological site on the island of Luzon.

This is one of 26 individuals found at the site of a fifth-century massacre on the Swedish island of Öland. This teenager was found lying on his side, which suggests a slower death. Other skeletons found in the homes and streets of the ringfort at Sandby borg show signs of sudden death by blows to the head.

The skeleton of a young woman and her fetus were found in a brick coffin dated to medieval Italy. Her skull shows an example of neurosurgery, and her child was extruded after death in a rare "coffin birth."

This portion of a whale skull was found at Calaveras Dam construction site in California, along with at least 19 others. Some of the pieces measure 3 feet long.

A Stone Age cow skull shows trepanation, a hole in the cranium that was created by humans as a surgical intervention or experiment.

On the left is a fossilized skull of our hominin ancestor Homo heidelbergensis, who lived 200,000 to 600,000 years ago. On the right is a modern human skull. Hominins had pronounced brow ridges, but modern human evolved mobile eyebrows as their face shape became smaller.

On the left is a 13,000-year-old footprint found in the sediment on Calvert Island, off the Canadian Pacific coast. On the right is a digitally enhanced image, showing details of the footprint.

The central platform at Star Carr in North Yorkshire, England, was excavated by a research team studying past climate change events at the Middle Stone Age site. The Star Carr site is home to the oldest evidence of carpentry in Europe and of built structures in Britain.

Researchers have been studying Archeopteryx fossils for 150 years, but new X-ray data reveals that the bird-like dinosaur may have been an "active flyer."

This wall with paintings is in the La Pasiega Cave in Spain. The ladder shape of red horizontal and vertical lines is more than 64,000 years old and was made by Neanderthals.

These perforated shells were found in Spain's Cave of Aircraft to be cave and date to between 115,000 and 120,000 years ago. Researchers believe these served as body ornamentation for Neanderthals.

The earliest modern human fossil ever found outside of Africa has been recovered in Israel. This suggests that modern humans left Africa at least 50,000 years earlier than previously believed. The upper jawbone, including several teeth, was recovered in a prehistoric cave site.

This is an excavated structure at the northern edge of the Grand Plaza at Teposcolula-Yucundaa in Oaxaca, Mexico. Researchers investigated the "pestilence" cemetery associated with a devastating 1545-1550 epidemic. New analysis suggests that salmonella caused an epidemic typhoid fever.
