Oldest-known aquatic reptiles probably spent time on land
Wed, 19 Sep 2018 11:14:57 EDT
A comprehensive analysis of Mesosaurus fossils shows that bones from adults share similarities with land-dwelling animals -- suggesting older Mesosaurus were semi-aquatic, whereas the juveniles spent their time in the water. This new research emphasizes the importance of thoroughly analyzing fossilized remains from across all stages of a reptile's life to get a full appreciation of its lifestyle and behavior.

Wild animals were routinely captured and traded in ancient Mesoamerica
Wed, 12 Sep 2018 14:44:30 EDT
New evidence from the Maya city of Copan, in Honduras, reveals that ancient Mesoamericans routinely captured and traded wild animals for symbolic and ritual purposes, according to a new study.
Discovery of the earliest drawing
Wed, 12 Sep 2018 13:35:31 EDT
The oldest known abstract drawing has been found in South Africa's Blombos Cave -- on the face of a flake of siliceous rock retrieved from archaeological strata dated to 73,000 years before the present. The work is at least 30,000 years older than the earliest previously known abstract and figurative drawings.
A prehistoric thirst for craft beer
Wed, 12 Sep 2018 11:19:07 EDT
Evidence suggests that stone mortars from Raqefet Cave, Israel, were used in brewing cereal-based beer millennia before the establishment of sedentary villages and cereal agriculture.
Understanding 6th-century barbarian social organization and migration through paleogenomics
Tue, 11 Sep 2018 13:21:15 EDT
Applying a comprehensive analysis of genetic, historical, and archeological factors in two 6th-century barbarian cemeteries, researchers have gleaned new insights into a key era known as the Migration Period that laid the foundation for modern European society.
DNA of early medieval Alemannic warriors and their entourage decoded
Wed, 05 Sep 2018 18:48:21 EDT
In 1962, an Alemannic burial site containing human skeletal remains was discovered in Niederstotzingen (Baden-W├╝rttemberg, Germany). Researchers have now examined the DNA of these skeletal remains.
The gens isiaca in Hispania: Egyptian gods in Roman Spain
Tue, 04 Sep 2018 11:47:59 EDT
Researchers have developed a geo-localized database which enables archaeological pieces from ancient religions to be located on the Iberian Peninsula. This platform, named ''The gens isiaca in Hispania'', provides a catalogue with more than 200 remains from the Roman age on Isis and other Egyptian gods.
Evolutionary origins of animal biodiversity
Mon, 03 Sep 2018 15:29:07 EDT
A new study has revealed the origins and evolution of animal body plans.
Early amber trade: Sicilian amber in Western Europe predates arrival of Baltic amber by at least 2,000 years
Wed, 29 Aug 2018 14:38:29 EDT
Amber from Sicily arrived in Iberia as early as the 4th Millennium BC, some 2,000 years before the appearance of Baltic amber to the peninsula. New study also suggests that Baltic amber reached Iberia via the Mediterranean not via direct trade with the North.
Discovery on East Asian monsoon dynamics
Tue, 28 Aug 2018 10:40:16 EDT
Scientists have identified four pervasive East Asian summer monsoon strengthening events at 1250, 1450, 1550, and 1900 CE and found that oceanic and continental settings could partially explain spatial differences in Asian summer monsoon trends at decadal to centennial scale.
Neanderthal mother, Denisovan father! Hybrid fossil
Wed, 22 Aug 2018 13:10:02 EDT
Up until 40,000 years ago, at least two groups of hominins inhabited Eurasia -- Neanderthals in the west and Denisovans in the east. Now, researchers have sequenced the genome of an ancient hominin individual from Siberia, and discovered that she had a Neanderthal mother and a Denisovan father.
Carbon reserves in Central American soils still affected by ancient Mayan deforestation
Mon, 20 Aug 2018 11:30:55 EDT
Deforestation is suspected to have contributed to the mysterious collapse of Mayan civilization more than 1,000 years ago. A new study shows that the forest-clearing also decimated carbon reservoirs in the tropical soils of the Yucatan peninsula region long after ancient cities were abandoned and the forests grew back.
DNA analysis of 6,500-year-old human remains with blue eye mutation
Mon, 20 Aug 2018 10:42:04 EDT
Scientists have discovered that waves of migration from Anatolia and the Zagros mountains to the Levant helped develop the Chalcolithic culture that existed in Israel's Upper Galilee region some 6,500 years ago. "Certain characteristics, such as genetic mutations contributing to blue eye color, were not seen in the DNA test results of earlier Levantine human remains," according to one of the researchers.
Prehistoric mummy reveals ancient Egyptian embalming 'recipe' was around for millennia
Wed, 15 Aug 2018 19:05:21 EDT
The ancient Egyptians developed sophisticated embalming treatments far earlier and across a wider geographical area than had been previously known, forensic tests on a well-known prehistoric mummy have revealed.
Dating the ancient Minoan eruption of Thera using tree rings
Wed, 15 Aug 2018 14:13:26 EDT
New analyses that use tree rings could settle the long-standing debate about when the volcano Thera erupted by resolving discrepancies between archeological and radiocarbon methods of dating the eruption, according to new research.
Origins and spread of Eurasian fruits traced to the ancient Silk Road
Tue, 14 Aug 2018 14:05:21 EDT
Studies of ancient plant remains from a medieval archaeological site in the Pamir Mountains of Uzbekistan have shown that fruits, such as apples, peaches, apricots, and melons, were cultivated in the foothills of Inner Asia. The archaeobotanical study is among the first systematic analyses of medieval agricultural crops in the heart of the ancient Silk Road.
Prehistoric peopling in southeast Asia: Genomics of Jomon and other ancient skeletons
Thu, 09 Aug 2018 09:34:27 EDT
Current evidence suggests that Southeast Asia was occupied by Hoabinhian hunter-gatherers until about 4000 years ago, but the human occupation history thereafter with farming economies remains unsettled. By sequencing 26 ancient human genomes (25 Southeast Asians, 1 Japanese Jomon), the history is shown to be more complex than previously thought; both Hoabinhian hunter-gatherers and East Asian farmers contributed to current Southeast Asian diversity. The results help resolve one of the long-standing controversies in Southeast Asian prehistory.
Lost Norse of Greenland fueled the medieval ivory trade, ancient walrus DNA suggests
Tue, 07 Aug 2018 19:28:42 EDT
New DNA analysis reveals that, before their mysterious disappearance, the Norse colonies of Greenland had a 'near monopoly' on Europe's walrus ivory supply. An overreliance on this trade may have contributed to Norse Greenland's collapse when the medieval market declined.
