Meet Xenoceratops: Canada's newest horned dinosaur

Artist reconstruction of Canada's oldest ceratopsid, Xenoceratops foremostensis (Zee-NO-Sare-ah-tops), from southern Alberta 78 million years ago. The new species of horned dinosaur was identified from fossils originally collected in 1958. Approximately 20 feet long and weighing more than 2 tons, the newly identified plant-eating dinosaur represents the oldest known large-bodied horned dinosaur from Canada. Research describing the new species is published in the October 2012 issue of the Canadian Journal of Earth Sciences. (Credit: © Julius T. Csotonyi 2012)

1000pa (Nov. 8, 2012) — Rocks dating back 3.4 billion years from south-west Greenland's Isua mountain range have yielded valuable information about the structure of Earth during its earliest stages of development. In these rocks, which witnessed the first billion years of Earth's history, a French-Danish team led by researchers from the 'Magmas...

Saber-toothed cats and bear dogs: How they made cohabitation work

This illustration depicts how the region of Cerro de los Batallones in central Spain likely looked 9 million years ago. Researchers led by the University of Michigan have used carbon records in the teeth of fossilized predators to shed light on how saber-toothed cats and bear dogs shared space and prey during the late Miocene period.

Were dinosaurs destined to be big? Testing Cope's rule

In the evolutionary long run, small critters tend to evolve into bigger beasts -- at least according to the idea attributed to paleontologist Edward Cope, now known as Cope's Rule. Using the latest advanced statistical modeling methods, a new test of this rule as it applies dinosaurs shows that Cope was right -- sometimes. (Credit: © Derrick Neill / Fotolia)

1000pa (Oct. 31, 2012) — Since the age of dinosaurs, most species of day-active mammals have retained the imprint of nocturnal life in their eye structures. Humans and other anthropoid primates, such as monkeys and apes, are the only groups that deviate from this pattern, according to a new study from The University of Texas at Austin and Midwestern University.

The findings, published in a forthcoming...

Exhaustive family tree for birds shows recent, rapid diversification

Analysis of the family tree shows when and where birds diversified — and that birds’ diversification rate has increased over the last 50 million years, challenging the conventional wisdom of biodiversity experts. (Credit: Image courtesy of Yale University)

1000pa (Oct. 31, 2012) — A Yale-led scientific team has produced the most comprehensive family tree for birds to date, connecting all living bird species -- nearly 10,000 in total -- and revealing...

First ever family tree for all living birds reveals evolution and diversification

Experts used the family tree to map out where the almost 10,000 species of birds live to show where the most diversification has taken place in the world. (Credit: Image courtesy of University of Sheffield)

1000pa (Oct. 31, 2012) — The world's first family tree linking all living bids and revealing when and where they evolved and diversified since dinosaurs walked the Earth has been created.

Experts used the family tree to map out where the almost 10,000...
