Teach to learn

Via Joho, I found a 2^nd grade class that maintains a blog. They've got a question that needs to be answered. The teacher who thought of this idea, using a blog to teach, should get teacher of the year. The concept is great, community teaching in a really organic form. The question is about dinosaurs and the kings of the jungles. Help them out and do your teaching duty for the day. My thoughts in their comments.
