Dinosaur of the day Pampadromaeus, one of the earliest known dinosaurs.

In dinosaur news this week:

• A new ceratopsian, Lokiceratops, had the biggest parietal frill ornamentation of any centrosaurine
• The asteroid killed off the non-avian dinosaurs, but volcanic eruptions may have set the stage for their mass extinction
• Dust from the asteroid impact may have been the biggest factor in the non-avian dinosaurs going extinct
• Studying fossils can help us understand the deep past and predict our future (and how vulnerable we are to going extinct)
• The Los Angeles County Natural History Museum is doing a poll to nickname their new green Jurassic sauropod
