Troodon posted a topic in Questions & AnswersAlthough identification of Hadrosaurid teeth in North America is very difficult or impossible some older publications by John Horner give us some information to help us with a few.

If anyone has publications that can add to the dentary information of teeth from North America please feel free to post it. Horner notes that on dentary teeth all Saurolophinae teeth have diamond-shaped crown whereas Lambeosaurinae teeth are more elongate see figure 13.4. So one may not be able
We all know that Magnapaulia was the biggest lambeosaurine hadrosaur that ever lived, but did you know that Kritosaurus means "broken lizard" due to the original specimen being found with broken nasal bones?

Hello, I was stopping through Indianapolis and gave their children's museum a try. It was surprisingly enjoyable! The museum covered topics from agriculture to racing to dinosaurs!

Following the path I emerged into a huge planetarium like structure filled with dinosaurs.
