Red Tide Fossils Point to Jurassic Sea Flood

University of Adelaide

Dinosaur-age fossilised remains of tiny organisms normally found in the sea have been discovered in inland, arid Australia – suggesting the area was, for a short time at least, inundated by sea water 40 million years before Australia’s large inland sea existed.

Asteroid Impact Grounded Bird Ancestors

Cornell University

An international team of scientists has concluded the asteroid that smashed into Earth 66 million years ago not only wiped out the dinosaurs, but erased the world’s forests and the species that lived in trees. The researchers say only small ground-dwelling birds survived the mass extinction, profoundly changing the course of bird evolution.

Earth’s Orbital Changes Have Influenced Climate, Life Forms For at Least 215 Million Years

Rutgers University-New Brunswick

Every 405,000 years, gravitational tugs from Jupiter and Venus slightly elongate Earth’s orbit, an amazingly consistent pattern that has influenced our planet’s climate for at least 215 million years and allows scientists to more precisely date geological events like the spread of dinosaurs, according to a Rutgers-led study. The findings are published online today in the Proceedings of the National Academy of Sciences.
