Fossil fuel emissions could soon start to cause headaches for archaeologists and paleontologists using radiocarbon dating to study artifacts. New research suggests the release of carbon-based gases into the atmosphere by vehicles and factories could alter radiocarbon measurements of ancient material. Radiocarbon dating measures levels of carbon-14, a naturally radioactive form of the atom. This […]

Velociraptor ancestor was ‘winged dragon’ ?
July 19th, 2015
Riffin Scientists have discovered a winged dinosaur – an ancestor of the velociraptor – that they say was on the cusp of becoming a bird.The 6ft 6in (2m) creature was almost perfectly preserved in limestone, thanks to a volcanic eruption that had buried it in north-east China and the 125-million year-old fossil suggests many other dinosaurs, […]
A vanished history of skeletonization in Cambrian comb jellies
July 12th, 2015
Riffin Ctenophores are traditionally regarded as “lower” metazoans, sharing with cnidarians a diploblastic grade of organization. Unlike cnidarians, where skeletonization (biomineralization and sclerotization) evolved repeatedly among ecologically important taxa (for example, scleractinians and octocorals), living ctenophores are characteristically soft-bodied animals. We report six sclerotized and armored ctenophores from the early Cambrian period. They have diagnostic ctenophore […]
Wendiceratops: Horned Dinosaur Evolutionary Tale
July 9th, 2015
Riffin Paleontologists say a dinosaur from 79 million years ago, known as Wendiceratops pinhornensis, could help them hook into the mysteries of how horned dinosaurs evolved. The species’ somewhat whimsical name is inspired by the place where its fossilized bones were found (the Pinhorn Provincial Grazing Reserve in Alberta) and the person who found them (Canadian […]
Great Karoo rocks reveals mass extinction
July 8th, 2015
Riffin An international team led by researchers from the Evolutionary Studies Institute (ESI) at the University of the Witwatersrand, Johannesburg, has obtained an age from rocks of the Great Karoo that shed light on the timing of a mass extinction event that occurred around 260 million years ago. This led to the disappearance of a diverse […]
Ground-based atomic clocks for monitoring volcanoes
July 5th, 2015
Riffin An international team led by scientists from the University of Zurich finds that high-precision atomic clocks can be used to monitoring volcanoes and potentially improve predictions of future eruptions. In addition, a ground-based network of atomic clocks could monitor the reaction of Earth’s crust to solid Earth tides. Atomic clocks measure time with unbelievable accuracy. […]
A New Eocene Casquehead Lizard from North America
July 3rd, 2015
Riffin A new fossil showing affinities with extant Laemanctus offers the first clear evidence for a casquehead lizard (Corytophanidae) from the Eocene of North America. Along with Geiseltaliellus from roughly coeval rocks in central Europe, the new find further documents the tropical fauna present during greenhouse conditions in the northern mid-latitudes approximately 50 million years ago […]
Helium leakage from Earth’s mantle ?
June 30th, 2015
Riffin UC Santa Barbara geologist Jim Boles has found evidence of helium leakage from Earth’s mantle along a 30-mile stretch of the Newport-Inglewood Fault Zone in the Los Angeles Basin. Using samples of casing gas from two dozen oil wells ranging from LA’s Westside to Newport Beach in Orange County, Boles discovered that more than one-third […]
Sefapanosaurus — SA’s new Sesotho dinosaur.
June 26th, 2015
Riffin South African and Argentinian palaeontologists have discovered a new 200-million-year-old dinosaur from South Africa, and named it Sefapanosaurus, from the Sesotho word “sefapano.” The researchers from South Africa’s University of Cape Town (UCT) and the University of the Witwatersrand (Wits University), and from the Argentinian Museo de La Plata and Museo Paleontológico Egidio Feruglio made […]
Dinosaur tracks reconstructed
June 24th, 2015
Riffin Twelve years ago, footprints of carnivorous dinosaurs were discovered and excavated in a quarry near Goslar. Paleontologists from the University of Bonn, working with Dinosaur Park Münchehagen and the State Museum of Hanover, have now created a three-dimensional digital model based on photographs of the excavation. The reconstruction of the discovery site suggests that carnivorous […]
