Most ancient pinworm yet found ?

An egg much smaller than a common grain of sand and found in a tiny piece of fossilized dung has helped scientists identify a pinworm that lived 240 million years ago.It is believed to be the most ancient pinworm yet found in the fossil record. The discovery confirms that herbivorous cynodonts — the ancestors of […]

Ancient marine ecosystem uncovered

Hidden secrets about life in Somerset 190 million years ago have been revealed by researchers at the University of Bristol and the Bath Royal Literary and Scientific Institution (BRLSI) in a new study of some remarkable fossils. Thanks to exceptional conditions of preservation, a whole marine ecosystem has been uncovered — and yet it was […]

Tetrapodophis :Four-legged snake fossil ?

Scientists have described what they say is the first known fossil of a four-legged snake. The limbs of the 120-or-so-million-year-old, 20-centimeter-long creature are remarkably well preserved and end with five slender digits that appear to have been functional. Thought to have come from Brazil, the fossil would be one of the earliest snakes found, suggesting […]

Radiocarbon Dating may Inaccurate Due To Fossil Fuel Emissions

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’ ?

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

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

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

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

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

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 […]
