Sorry for the delay on the comic this week!
I saw a great presentation by paleontologist Jack Horner over at Love in the Time of Chasmosaurs on the "condensing" of certain Dinosaur species--you'll probably remember some of this with the Triceratops/Torosaurus debacle a short while back, and he presents the information in a pretty informative and entertaining way, definitely give it a look if you have 20 minutes to spend on it.
