Anyhow, the most surprising discovery from this visit concerned Dimetrodon, which when I was a child was one of my favorite dinosaurs from my extensive collection of plastic dinosaur toys. My Dimetrodon toy looked vaguely like the one below, minus the "Dino-Strike Clamping Jaws".
What an awesome sail on his/her back, right? Coolest dinosaur ever, or so I thought until my weekend stroll past the "Synapsid vs Diapsid" section of the evolving planet exhibit. It was in this section that one of my childhood dino dreams died, and out of the ashes rose what I like to call the phoenix of discovery! I discovered that Dimetrodon was not a dinosaur, but was instead our ancestor!!!!! While that sinks in, here are some cool Dimetrodon pictures.
