Triceratops relative 'Wendi' sported a fantastic frill

The discovery of a 79-million-year-old frilled and horned relative of Triceratops is shedding light on the early evolution of the ceratopsid’s distinctive look. The new specimen, discovered in a quarry in southern Alberta, Canada, and described recently in PLOS ONE, was named Wendiceratops pinhornensis after the famed fossil hunter Wendy Sloboda of the University of Lethbridge in Alberta, who discovered the site in 2010.

Benchmarks: October 4, 1915: Dinosaur National Monument Founded

While moving across the country from California to Michigan two years ago, I stopped at Dinosaur National Monument, or “Dinosaur,” which today covers 85,000 hectares and straddles the northern portion of the border between Colorado and Utah. I camped at the Green River Campground on the Utah side, and from there, Split Mountain, on the western margin of the east-west-trending Uinta Mountains, glowed violet-pink in the sunset light.

Dinosaurs used the same nests repeatedly

Fossil dinosaur eggs and nests offer clues about dinosaur development and behavior: Based on past work, for example, scientists have thought that some dinosaurs, like oviraptors, brooded, or sat on their eggs, much like modern birds do. Now, the results of a new study describing two fossil egg nests suggest that some dinosaurs used the same nesting sites again and again.

Gender equity in dino bones

Modern birds like cardinals and peacocks offer some of the most dramatic examples of sexual dimorphism on Earth, with males and females varying in size and/or displaying different plumage, among other differences. But whether the two sexes of birds’ dinosaur ancestors also possessed different physical characteristics has long been debated. Now, in a new study, scientists using state-of-the-art measuring techniques to look at Protoceratops — a frilled, horned relative of Triceratops that’s found abundantly in the fossil record — are questioning past notions about whether the sex of specimens can be distinguished based on their fossils.

De-evolving the bird beak

The transition from dinosaurs with snouts to birds with beaks was a pivotal change in the evolution of dinosaurs into birds during the Late Mesozoic. Now, biologists have partially reversed this process by transforming chicken embryos into specimens with snout and palate configurations similar to those of small dinosaurs like Velociraptor and Archaeopteryx.

Makeovers for two popular dinosaurs

Two of the most recognizable dinosaurs are getting image makeovers. According to recent research, tyrannosaurs weren’t only fearsome predators with a taste for other species, but also may have been cannibals; and Brontosaurus, long thought to be obsolete — as a distinct genus at least — may be making a comeback.

One-of-a-kind dinosaur skull goes digital

Some dinosaur species are only known from a single skull, and gaining access to study such rare and fragile fossils can be difficult, especially if the skull is stored in a far-flung place like a museum in Mongolia. Now, a new technique using medical CT scans and digital imaging to create a digital model of fossils will allow such rarities to be studied by lots of eyes, all over the world, without damaging or transporting the delicate original.

Travels in Geology: Exploring Connecticut's Ancient Rift Valley

Fifty years ago, a bulldozer operator in Connecticut discovered one of the largest dinosaur tracksites in North America, now preserved at Dinosaur State Park. The formation of the tracksite, which lies in the remnant of a Triassic rift valley, is linked with the demise of the supercontinent Pangea.
