Latest Extinction events Stories
The massive asteroid that crashed into the ocean near the coast of Mexico millions of years ago (and is believed to have wiped out the dinosaurs) was likely the catalyst for a series of worldwide volcanic eruptions contributed to the extinction event, new research claims.
The theory that all animal life emerged from the sea has been well covered, but much less is known about the creatures that went back. Whales, dolphins, seals and sea turtles are examples of marine tetrapods--an exceptional group of animals that moved from the sea to the land and back again.
Chuck Bednar for redOrbit.com - @BednarChuck New evidence of severe losses in brachiopods in the northern Boreal latitudes around the island of Spitsbergen suggest that the controversial Capitanian extinction event that occurred about 262 million years ago should be classified as a true “mass extinction” event. Previously, the Capitanian extinction event was known only from equatorial settings, and thus its status as a full-fledged global crisis was controversial. However, the...
For the first time, scientists plan to conduct an expedition to collect and analyze core samples from the 125-mile-wide Chicxulub impact site in Mexico, a crater believed to have been caused by the asteroid that wiped out the dinosaurs more than 65 million years ago.
The Triassic extinction took place over 200 million years ago and a new study has found that a major factor in that global die-off was the oceans becoming toxic, according to a new study in the journal Geology.
A nearly 250 mile (400 km) wide impact zone recently discovered in Central Australia is being called the largest asteroid-caused craters ever discovered, according to research published earlier this month in the international earth sciences journal Tectonophysics.
Environment was just right--a 'Goldilocks effect'-- for well-preserved swim tracks from the Early Triassic age.
Scientists are calling it Eohupehsuchus brevicollis.
Paleontologists from the University of Zurich now reveal that climate catastrophes in the past played a crucial role in the dominance of ray-finned fish today.
Geologists from Trinity College Dublin have rewritten the evolutionary history books by finding that oxygen-producing life forms were present on Earth some 3 billion years ago – a full 60 million years earlier than previously thought.
