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.
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.
Scientists from China and the United States reported discovering fossil footprints for animal appendages in the Ediacaran Period (about 635-541 million years ago) in China. This is considered the earliest animal fossil footprint record.
New research from Northumbria University has revealed that metal-related pollution began in the Balkans more than 500 years before it appeared in western Europe, and persisted throughout the Dark Ages and Medieval Period, meaning the region played a far bigger role in mineral exploitation than previously believed.
In just over 1,000 years, Icelanders have gone through numerous changes in their gene pool, to the extent that Icelanda's first settlers, who came to the island from Norway and the British and Irish isles between the years 870 and 930, are much more similar to the inhabitants of their original home countries than to Iceland's present-day inhabitants.
A tiny Egyptian mummy long believed to be that of a hawk is actually a rare example of a near-to-term, severely malformed fetus, says an examination led by mummy expert Andrew Nelson of Western University in London, Canada.
Analysis of the skeletal remains of a Mesolithic man found in a cave on a Croatian island has revealed microscopic fish and plant remains in the dental plaque of a tooth -- a first-time discovery for the period and region.
