Ceropod vs. sauropods

Arianna decided to discuss ceropods and sauropods yesterday. I asked if she was sure that the triceratops was a ceropod. She gave me that "well, duh" look..I told her I didn't think it was and looked it up...she was right..I hate it (and love it!) when she's right...I think the victory dance around the living room was a little over the top though. Lol!
