Class is in session over at Coursera, they have a dinosaur class starting this week.   It’s Dino 101.  A good introduction to dinosaurs, how they lived, and the world they lived in.  Your friendly blogger took the class a few years ago.  It’s a good class with interesting content.  Professor Phil Currie is one of the instructors.   You may have heard him speak at a previous Paleofest in Rockford, IL.
