Middle Earth Preserved in Giant Bird Dung

While the giant birds that once dominated New Zealand are all extinct, a study of their preserved dung (coprolites) has revealed many aspects of their ancient ecosystem, with important insights for ongoing conservation efforts.

Researchers Pose Revolutionary Theory on Horse Evolution

FigureA.jpg

Scientists have long wondered how the horse evolved from an ancestor with five toes to the animal we know today. While it is largely believed that horses simply evolved with fewer digits, researchers at New York Institute of Technology College of Osteopathic Medicine (NYITCOM) pose a new theory that suggests remnants of all five toes are still present within the hooves of the horse.

New Turkey-Sized Dinosaur From Australia Preserved in an Ancient Log-Jam

Diluvicursorpickeringi2.png

The partial skeleton of a new species of turkey-sized herbivorous dinosaur has been discovered in 113 million year old rocks in southeastern Australia. The fossilized tail and foot bones give new insight into the diversity of the small, bipedal herbivorous dinosaurs called ornithopods.

Mass Extinctions Remove Species but Not Ecological Variety

Though mass extinctions wiped out staggeringly high numbers of species, they barely touched the overall "functional" diversity--how each species makes a living, be it filtering phytoplankton or eating small crustaceans, burrowing or clamping onto rocks. University of Chicago scientists documented this surprising trend in a study on extinctions published Jan. 5 in the Proceedings of the National Academy of Sciences.

The Secret World of Dinosaur Tracks

Scans of fossilized dinosaur prints show how some dinosaur feet moved not just on top of but through the earth. The results of this study will be presented at the annual conference of the Society for Integrative and Comparative Biology in San Francisco, CA on January 4, 2018

Oldest Fossils Ever Found Show Life on Earth Began Before 3.5 Billion Years Ago

Researchers at UCLA and the University of Wisconsin–Madison have confirmed that microscopic fossils discovered in a nearly 3.5 billion-year-old piece of rock in Western Australia are the oldest fossils ever found and indeed the earliest direct evidence of life on Earth.

Researchers Capture Oldest Ice Core Ever Drilled Outside the Polar Regions

The oldest ice core ever drilled outside the polar regions may contain ice that formed during the Stone Age—more than 600,000 years ago, long before modern humans appeared.
