I've taken paleontological courses before, but this one is different from the usual 20-minutes-long videos. Topics are brought up in 1-3 minute long videos, enough to keep you interested, but yet full of information. Practice quizzes were also helpful, and final quizzes were easy enough after watching the videos and solving the practice quizzes. I liked the real-life problems and applications, lab videos, and recent discoveries - this course gives you the latest updates in form of roundup videos, and discusses the most interesting forum questions as well, so it's easy to get and stay involved. All in all, a great course, I'd like to see a sequel.
