Study of Giant Viruses Shakes Up Tree of Life

A new study of giant viruses supports the idea that viruses are ancient living organisms and not inanimate molecular remnants run amok, as some scientists have argued. The study may reshape the universal family tree, adding a fourth major branch to the three that most scientists agree represent the fundamental domains of life. The new findings […]

Research: Ichthyosaur Survival across the Jurassic–Cretaceous Boundary

Ichthyosauria is a diverse clade of marine amniotes that spanned most of the Mesozoic. Until recently, most authors interpreted the fossil record as showing that three major extinction events affected this group during its history: one during the latest Triassic, one at the Jurassic–Cretaceous boundary (JCB), and one (resulting in total extinction) at the Cenomanian-Turonian […]

World’s Smallest Fossil Footprints: Small Amphibian Roamed Earth 315 Million Years Ago

A new set of fossil footprints discovered in Joggins, Nova Scotia, near Amherst, have been identified as the world’s smallest known fossil vertebrate footprints.  The footprints were found at the UNESCO World Heritage Site, the Joggins Fossil Cliffs. A fossil specimen of the ichnogenusBatrachichnus salamandroides was collected by local amateur paleontologist Gloria Melanson, daughter of Don […]

‘Absolutely amazing’ fossil excavated near Richmond

Curator at Kronosaurus Korner museum at Richmond says the well-preserved fossil of a baby Ichthyosaur, being excavated and prepared this week, is “absolutely amazing”. Paul Stumkat says the fossil, discovered last year, is a rare find, “what we’ve got here is probably the most complete baby Ichthyosaur ever found in Australia. This thing is absolutely […]

Strange predatory dinosaur from Europe’s Late Cretaceous

By describing a new double-clawed and highly-unusual relative of Velociraptor, paleontologists have answered a long-standing question: what did the Late Cretaceous predatory dinosaurs in Europe look like? Balaur bondoc, described this week in Proceedings of the National Academy of Sciences, is the first reasonably complete skeleton of a meat-eating dinosaur from the final 60 million years of the […]

Scientists Obtain Rocks Moving Into Seismogenic Zone

An international group of scientists aboard the Deep-Sea Drilling Vessel CHIKYU, operated by the Japan Agency for Marine-Earth Science and Technology (JAMSTEC) for the Integrated Ocean Drilling Program (IODP), return from a 40-day scientific expedition off the shore of the Kii Peninsula, Japan on Oct. 10, 2009. Expedition 322, called “Subduction Inputs” in the multi-stage […]

New World Drilling-Depth Record of Scientific Ocean Drilling

Scientific deep sea drilling vessel Chikyu sets a world new record by drilling down and obtains rock samples from deeper than 2,111 meters below the seafloor off Shimokita Peninsula of Japan in the northwest Pacific Ocean. The Japan Agency for Marine-Earth Science and Technology (JAMSTEC), the implementing organization for scientific expedition aboard theChikyu, announced this achievement on […]

Fossil records ‘crab’ death march

The behaviour of an ancient horseshoe crab in its final moments before death has been captured in the fossil record. A 9.7m-long trackway was created around 150 million years ago when a horseshoe crab fell into a lagoon. The find is of interest because the fossil of the animal itself is present at the end of the […]

Darwinopterus: New flying Reptile

Researchers in China and the UK say they have discovered the fossils of a new type of flying reptile that lived more than 160 million years ago. The find is named Darwinopterus, after Charles Darwin. Experts say it provides the first clear evidence of a controversial idea called modular evolution. The 20 new fossils found in […]

Sinornithosaurus : Bird-like dinosaur was ‘venomous’

A bird-like dinosaur that prowled an ancient forest 125 million years ago used venom to subdue its prey, according to a new theory. Sinornithosaurus‘s upper teeth resemble those of “rear-fanged” snakes which bite their prey and channel venom into the wound.The dinosaur probably fed on the abundant birds which inhabited what is now north-east China.The […]
