Revueltosaurus skeleton unearthed upsets dinosaur taleThe fossilized skeleton of a small crocodile relative excavated last year at Petrified Forest National Park in Arizona throws a wrench into theories of how and where the dinosaurs arose more than 210 million years ago at the end of the Triassic Period.
X-ray fluorescence recovers ancient textIn an unusual collaboration among scientists and humanists, a Cornell University team has demonstrated a novel method for recovering faded text on ancient stone by zapping and mapping 2,000-year-old inscriptions using X-ray fluorescence (XRF) imaging.
Studies of amazonian languages challenge linguistic theories
In an unusual collaboration among scientists and humanists, a Cornell University team has demonstrated a novel method for recovering faded text on ancient stone by zapping and mapping 2,000-year-old inscriptions using X-ray fluorescence (XRF) imaging.
Big game hunters killed off slothsPrehistoric big game hunters and not the last ice age are the likely culprits in the extinction of giant ground sloths and other North American great mammals such as mammoths, mastodons and saber-toothed tigers, says a University of Florida researcher.
New look at ancient diet dogma
A Penn State researcher is part of the team that developed techniques that have generated insights into dietary divergences between some of our human ancestors, allowing scientists to better understand the evolutionary path that led to the modern-day diets that humans consume.
Newly discovered birdlike dinosaur is oldest raptor ever found in Aouth AmericaThe recent discovery of a 90-million-year-old dinosaur in Patagonia demonstrates that dromaeosaurs, a group of carnivorous theropods that includes Velociraptor and is closely related to birds, originated much earlier than previously thought.
Oldest date evidence of cattle in Southern Africa found
A team of researchers working with colleagues from the Botswana National Museum shed new light on the questions of when cattle were brought to southern Africa and from where

India's smoking gun: dino-killing eruptionsNew discoveries about the timing and speed of gigantic, 6500-foot (2-km) thick lava flows that poured out of the ground 65 million years ago could shift the blame for killing the dinos
Still shellfish after 425 million yearsAn ancient shellfish not seen for 425 million years is recreated in vivid 3D images, following a unique fossil find in the UK.
Protective footwear started nearly 30,000 years agoThose high-tech, air-filled, light-as-a-feather sneakers on your feet are a far cry from the leather slabs our ancestors wore for protection and support. But believe it or not, our modern day Nikes and Reeboks are direct descendents of the first supportive footwear that new research suggests came into use in western Eurasia between 26,000 and 30,000 years ago.
New understanding of human sacrifice in early Peru
A study published in the August/October issue of Current Anthropology, reports on new archaeological evidence regarding the identities of human sacrifice victims of the Moche society of Peru.
Inka textile devices served as business ledgersWhile most ancient cultures recorded civil matters and business transactions by inscribing characters on 2-dimensional sheets, new evidence shows Peru's original inhabitants used a 3-dimensional system of knotted strings to keep track of things.
Extinct giant deer's descendant found in UK
UCL (University College London) scientists have found that the closest living relative to the extinct Irish Elk (giant deer) lives on their shores. The team tested for DNA and skeletal features to prove that the giant deer - which roamed across Europe and Siberia with prehistoric man and is the subject of numerous cave drawings - has its DNA in common with the fallow deer, one of the most widespread deer in the UK since their introduction by the Normans in the eleventh century.
Skull study sheds light on dinosaur diversityWith their long necks and tails, sauropod dinosaurs—famous as the Sinclair gasoline logo and Fred Flintstone's gravel pit tractor—are easy to recognize, in part because they all seem to look alike.
Morphology of fossil salamanders reflects climate change
A fossil record of the Tiger Salamander (Ambystoma tigrinum) shows population-wide changes in body size and morphology in response to climate change over the last 3,000 years. The observed changes offer predictions about the response of the species to future climate change, and the impact on the ecosystem.
The roots of civilization trace back to … rootsAbout five to seven million years ago, when the lineage of humans and chimpanzees split, edible root plants similar to rutabagas and turnips may have been one of the reasons.
Neanderthal teeth grew no faster than comparable modern humans'
Recent research suggested that ancient Neanderthals might have had an accelerated childhood compared to that of modern humans but that seems flawed, based on a new assessment by researchers from Ohio State University and the University of Newcastle.
E-Science records roman finds
Twenty first century e-Science met the ancient Roman world in a Hampshire field this summer. For the first time, archaeologists excavating at the Silchester Roman site used e-Science techniques to record their finds.
Long-sought maya city found in GuatemalaA team of scientists including Marcello Canuto, professor of anthropology at Yale, has found incontrovertible proof of Site Q, a long-speculated Maya city, during a mission to the northwest Peten region of Guatemala.
