Over two million years ago, a third of the largest marine animals like sharks, whales, sea birds and sea turtles disappeared. This previously unknown extinction event not only had a consid-erable impact on the earth's historical biodiversity but also on the functioning of ecosystems. This has been demonstrated by researchers at the University of Zurich.
This shows that the expansion of grasslands isn't solely due to drought, but more complex climate factors are at work, both for modern Africans now and ancient Africans in the Pleistocene.
Water bottles replicated in the traditional method used by Native Californian Indians reveal that the manufacturing process may have been detrimental to the health of these people. The study is published this week in the open access journal Environmental Health.
Skeletal evidence shows that, hundreds of years after the Roman Republic conquered most of the Mediterranean world, coastal communities in what is now south and central Italy still bore distinct physical differences to one another -- though the same could not be said of the area around Rome itself.
It is likely to be one of the oldest prosthetic devices in human history: Together with other experts, Egyptologists from the University of Basel have reexamined an artificial wooden big toe. The find is almost 3,000 years old and was discovered in a female burial from the necropolis of Sheikh 'Abd el-Qurna close to Luxor. This area is currently being studied using state-of-the-art methods.
DNA found at archaeological sites reveals that the origins of our domestic cat are in the Near East and ancient Egypt. Cats were domesticated by the first farmers some 10,000 years ago. They later spread across Europe and other parts of the world via trade hub Egypt. The DNA analysis also revealed that most of these ancient cats had stripes: spotted cats were uncommon until the Middle Ages.
Huge pulses of volcanic activity are likely to have played a key role in triggering the end Triassic mass extinction, which set the scene for the rise and age of the dinosaurs, new Oxford University research has found.
Gihon Spring, was crucial to the survival of its inhabitants, and archaeologists had uncovered the remains of a massive stone tower built to guard this vital water supply. Based on pottery and other regional findings, the archaeologists had originally assigned it a date of 1,700 BCE. But new research conducted at the Weizmann Institute of Science provides conclusive evidence that the stones at the base of the tower were laid nearly 1,000 years later.
Being a member of the international scientific team, a student from the Faculty of Geology of the Lomonosov Moscow State University has taken part in study and description of a new genus and species of the ancient marine reptile, called pliosaur.
Using advanced imaging technology, Tel Aviv University researchers have discovered a hitherto invisible inscription on the back of a pottery shard dating from 600 BCE that has been on display at The Israel Museum for more than 50 years.
