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 […]

Oxygen Theory Of Mass Extinction Questioned By New Research Findings

Several theories have been proposed by scientists to explain the two mass extinction events which took place on the earth 250 and 200 million years ago. The Permian-Triassic catastrophe (250 million years ago) was the worst of all five of the mass extinction events to ever have befallen the earth. It eradicated almost 95% of […]

New Permian Fish Discovered in Brazil

Dr. Eliseu Vieira Dias of the State University of Western Paraná (UNIOESTE) has announced the discovery of a new species of deep-bodied fish that prowled ancient rivers and lakes in the South American part of Gondwana during Permian period.   A fossil of Paranaichthys longianalis (E.V. Dias) A paper in the journal Zootaxa describes a new species […]

When continents collide: A new twist to a 50 million-year-old tale

Fifty million years ago, India slammed into Eurasia, a collision that gave rise to the tallest landforms on the planet, the Himalaya Mountains and the Tibetan Plateau. India and Eurasia continue to converge today, though at an ever-slowing pace. University of Michigan geomorphologist and geophysicist Marin Clark wanted to know when this motion will end […]

Tibetan Plateau May Be Older Than Previously Thought

The growth of high topography on the Tibetan Plateau in Sichuan, China, began much earlier than previously thought, according to an international team of geologists who looked at mountain ranges along the eastern edge of the plateau. The Indian tectonic plate began its collision with Asia between 55 and 50 million years ago, but “significant […]

Plant-Eating Dinosaur Discovered in Antarctica

For the first time, the presence of large bodied herbivorous dinosaurs in Antarctica has been recorded. Until now, remains of sauropoda — one of the most diverse and geographically widespread species of herbivorous dinosaurs — had been recovered from all continental landmasses, except Antarctica. Dr. Ignacio Alejandro Cerda, from CONICET in Argentina, and his team’s […]

Listening To Rocks Helps Researchers Better Understand Earthquakes

When Apollo punished King Midas by giving him donkey ears, only the king and his barber knew. Unable to keep a secret, the barber dug a hole, whispered into it, “King Midas has donkey ears,” and filled the hole. But plants sprouted from the hole, and with each passing breeze, shared the king’s secret. Earth, […]
