• 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

• Utahraptor was discovered around the time the movie Jurassic Park came out, more recently a new huge block of Utahraptors was found
• Paleontologist Bob Bakker tells a compelling story of a Utahraptor through her eyes in his novel Raptor Red
• Paleontologist John Ostrom named Deinonychus in 1969 (which also has ties to Jurassic Park)
• "The first definitive dromaeosaur with a reasonably complete skeleton ever found in the US" is nicknamed "Julietraptor"
