This semester I took a class in Geology. I was a bit upset when we came to the anticipated information about dinosaurs, and I learned that my beloved tree flyer from land before time is not a pterodactyl.
This is a nice site that lists over 300 dinosaurs. I stumbled upon it while searching for how to pronounce various dinosaur names. In addition to the pronunciation, I like the charts that show the relative size of each dinosaur to man.
