A new study by a team of international experts, led by University of Witwatersrand Ph.D. candidate Kathleen Dollman and Professor Jonah Choiniere published today in the American Museum Novitates, endeavoured to further explore the mouth of one of the earliest occurring and least understood groups of crocodilians, the shartegosuchids.
A new way of dating skeletons by using mutations in DNA associated with geography will avoid the difficulties and inaccuracies sometimes associated with existing dating methods. The technique will enable a better understanding of historical developments from the beginning of the Neolithic period, through the Bronze and Iron Ages.
The intensive whaling that has pushed many species to the brink of extinction today may be several centuries older than previously assumed. This view is held by archaeologists from Uppsala and York whose findings are presented in the European Journal of Archaeology.
Though scholars have long assumed that Aztec and Mixtec turquoise artifacts uncovered in Mesoamerica were imported from the American Southwest, a new isotopic analysis suggests these artifacts likely derived from Mesoamerican sources.
New research overturns more than a century of claims that the source of turquoise used and revered by ancient civilizations in Mexico, such as the Aztecs, came from the Southwestern US Geochemical analyses show the origin of the turquoise is Mesoamerica (Central Mexico to Central America).
Agricultural activity by humans more than 2,000 years ago had a more significant and lasting impact on the environment than previously thought. The finding -- discovered by a team of international researchers led by the University of British Columbia -- is reported in a new study published today in the journal Science Advances.
A new International Journal of Nautical Archaeology study provides precise geographic information for the preservation, long-term research, and future use of a historically important World War II battle site on the seafloor off the coast of Okinawa, Japan.
Are crowd-sourced photos taken with mobile phones useful in collecting analytics for antiques? Can smell be used to classify degradation of plastic artifacts in museums? How are cannonballs from shipwrecks affected by conservation techniques? The answers to all these questions are found in a Special Issue on heritage science published by the journal Angewandte Chemie.
An international team of researchers led by the Max Planck Institute for the Science of Human History has analyzed two 3,800-year-old Y. pestis genomes that suggest a Bronze Age origin for bubonic plague. The study, published in the journal Nature Communications, shows that this strain is the oldest sequenced to date that contains the virulence factors considered characteristic of the bubonic plague and is ancestral to the strain that caused the Black Death.
The first African fossils of Devonian tetrapods (four-legged vertebrates) show these pioneers of land living within the Antarctic circle, 360 million years ago.
