EurekAlert [USA], 14-Dec-2011
Despite their extinction millions of years ago, Triceratops continue to
incite controversy. In the latest chapter, researchers present further
evidence that three genera thought at one time or another to be distinct
-- Triceratops, Torosaurus, and Nedoceratops -- actually represent
different individuals that all belong to the Triceratops genus. The
work, led by John Scannella of Montana State University and published in
the Dec. 14 issue of the online journal PLoS ONE, focuses on one
particular specimen -- a single skull -- that has been the subject of
considerable debate.

Dinosaurs with killer claws yield new theory about flight
PhysOrg.com [USA], December 14, 2011
New research from Montana State University's Museum of the Rockies has
revealed how dinosaurs like Velociraptor and Deinonychus used their
famous killer claws, leading to a new hypothesis on the evolution of
flight in birds. In a paper published Dec. 14 in PLoS ONE, MSU
researchers Denver W. Fowler, Elizabeth A. Freedman, John B. Scannella
and Robert E. Kambic (now at Brown University in Rhode Island), describe
how comparing modern birds of prey helped develop a new behavior model
for sickle-clawed carnivorous dinosaurs like Velociraptor. "This study
is a real game-changer," said lead author Fowler. "It completely
overhauls our perception of these little predatory dinosaurs, changing
the way we think about their ecology and evolution."

Dinosaur bone found in Sunderland garden
BBC, 13 December 2011
A dinosaur bone believed to be up to 130 million years old has been
found in a back garden in Sunderland. The bone, thought to be from a
dinosaur called Iguanodon, was found by a member of the public when they
were digging among tree roots in their garden. It was handed in by the
anonymous discoverer to Sunderland Museum and Winter Gardens to see what
their history experts made of it. Museum manager Jo Cunningham said it
was an "amazing find".
