A study of more than 6,000 marine fossils from the Antarctic shows that the mass extinction event that killed the dinosaurs was sudden and just as deadly to life in the polar regions. Previously, scientists had thought that creatures living in the southernmost regions of the planet would have been in a less perilous position during the mass extinction event than those elsewhere on Earth.

Some dinosaur feathers may have been more fab than drab. Take this ostrich-size adult dinosaur called  Ornithomimus edmontonicus, which would have been adorned with stringy down %u2014 filamentlike feathers up to 2 inches (5 centimeters) long. The sexually mature adult also had markings on its winglike forelimbs that suggest it bore longer feathers that were absent from the juveniles of the species that were also discovered. As such, the researchers think the feathers may have been used for…

Scientists have lately discovered two plankton-munching Rhinconichthys species, each with their own ancient skull. This now brings the genus to a total of three distinct species from three separate regions in the world. (Photo : Robert Nicholls | DePaul University)
