Say hello to one of Triceratops’ oldest relatives.
Scientists recently discovered the fossilized bones of a striking new species of horned dinosaur in southern Alberta, Canada. The 200-plus fossils are believed to have belonged to four specimens of Wendiceratops pinhornenis–three adults and one young dino.
According to the researchers, W. pinhornenis lived about 79 million years ago. Measuring about 6 meters (20 feet) in length and weighing more than a ton, it sported a parrot-like beak suited to eating scrubby plants. And while the dinosaur likely had a wide frill extending from its neck and horns over the eyes, its most bizarre feature was the giant horn on its nose. It’s the earliest known example of a tall, upright nose horn in the horned dinosaur family.

A thin disk of dark matter running through the Galaxy might be behind the large meteorite strikes that are thought to be responsible for some of Earth’s mass extinctions, including that of the dinosaurs, two theoretical physicists have proposed.
The model is based on a hypothetical form of dark matter described by the authors and their collaborators last year as a means to solve a separate cosmic conundrum. The existence of such a ‘dark disk’ could be tested soon by astronomical observations.
Mario Livio, an astrophysicist at the Space Telescope Science Institute in Baltimore, Maryland, who was not involved in the research, says that the latest idea, which brings together two speculative and very different theories, is “very interesting”, even if the evidence supporting it is far from compelling.

Mexican paleontologists say they have uncovered 50 vertebrae believed to be a full dinosaur tail in the northern desert of Coahuila state.
The National Institute of Anthropology and History says the tail is about 15 feet (5 meters) long and resembles that of a hadrosaur or crested duckbill dinosaur.
An institute Monday says it’s not yet possible to confirm the species, but it would be the first full tail of that kind in Mexico.
Paleontologist Felisa Aguilar says they uncovered roughly half of the dinosaur, which was 36 feet (12 meters) long and lived about 72 million years ago.
The excavation took 20 days in the municipality of General Cepeda in the northern state that borders Texas.

Researchers in northeastern Spain say they’ve uncovered hundreds of dinosaur egg fossils, including four kinds that had never been found before in the region. The eggs likely were left behind by sauropods millions of years ago.
Eggs, eggshell fragments and dozens of clutches were nestled in the stratigraphic layers of the Tremp geological formation at the site of Coll de Nargó in the Spanish province of Lleida, which was a marshy region during the Late Cretaceous Period, the researchers said.
“Eggshells, eggs and nests were found in abundance and they all belong to dinosaurs, sauropods in particular,” the study’s leader, Albert García Sellés from the Miquel Crusafont Catalan Palaeontology Institute, told Spanish news agency SINC this week.

How did the largest of all dinosaurs evolve necks longer than any other creature that has ever lived? One secret: mostly hollow neck bones, researchers say.
The largest creatures to ever walk the Earth were the long-necked, long-tailed dinosaurs known as the sauropods. These vegetarians had by far the longest necks of any known animal. The dinosaurs’ necks reached up to 50 feet (15 meters) in length, six times longer than that of the current world-record holder, the giraffe, and at least five times longer than those of any other animal that has lived on land.

SAN FRANCISCO — Volcanic activity in modern-day India, not an asteroid, may have killed the dinosaurs, according to a new study.
Tens of thousands of years of lava flow from the Deccan Traps, a volcanic region near Mumbai in present-day India, may have spewed poisonous levels of sulfur and carbon dioxide into the atmosphere and caused the mass extinction through the resulting global warming and ocean acidification, the research suggests.
