Fossilised footprint tracks, recently discovered within the Hanna Formation in Wyoming, USA, which have been dated to 58 million years ago, may represent the earliest evidence of mammals gathering by the sea, according to a study published in Scientific Reports. Findings suggest that mammals may have first used marine habitats at least 9.4 million years earlier than previously thought, in the late Paleocene (66-56 million years ago), rather than the Eocene (56-33.9 million years ago).
Climate change may be accelerating the degradation of ancient rock paintings in Indonesia, including the oldest known hand stencil in the world which dates back to 39,900 years ago, according to a study published in Scientific Reports.
Meradeth Snow, a University of Montana researcher and co-chair of UM's Department of Anthropology, was part of an international team that used human "paleofeces" to discover that ancient people had far different microorganisms living in their guts than we do in modern times.
Geochemical evidence reveals that armies in the Battles of Himera were a mixture of locals and outsiders, according to a study published March 24, 2021 in the open-access journal PLOS ONE by Katherine Reinberger of the University of Georgia, US, and colleagues. These data contradict certain claims made in historical accounts by ancient Greek writers.
A research team including Binghamton University anthropologists Carl Lipo and Robert DiNapoli explore how complex community patterns in Easter Island helped the isolated island survive from its settlement in the 12th to 13th century until European contact.
A new study lead by Dr Kimberley Chapelle of the American Museum of Natural History and Honorary Research Fellow at the University of the Witwatersrand suggests that growth of the dinosaur Massospondylus carinatus varied season-to-season, more like a tree than a puppy or a baby human. Massospondylus was a medium sized dinosaur, up to 500kg in body weight, that lived in the Early Jurassic. The study suggests that Massospondylus' growth directly responded to its environmental conditions.
In a new study, an international team led by Sebastian Stumpf from the University of Vienna describes a fossil skeleton of an ancient shark, which is assigned to a new, previously unknown genus and species.
Aqueducts are very impressive examples of the art of construction in the Roman Empire. Even today, they still provide us with new insights into aesthetic, practical, and technical aspects of construction and use. Scientists investigated the longest aqueduct of the time, the 426-kilometer-long Aqueduct of Valens supplying Constantinople, and revealed new insights into how this structure was maintained back in time.
A new study looking at the evolutionary history of the human oral microbiome shows that Neanderthals and ancient humans adapted to eating starch-rich foods as far back as 100,000 years ago, which is much earlier than previously thought.
A ceremonial tsantsa - or shrunken head - was authenticated and repatriated to Ecuador in 2019, after it had been discovered amongst stored exhibits at Mercer University, USA. The history of the artefact and the process of its authentication - which involved CT scans and assessment of 33 criteria such skin and hair features - are described in a study published in Heritage Science.
