Roger is the name Buck gave to a pteranodon who appears in the third Ice Age film. He is a male pteranodon who was used by Buck, alongside with Crash and Eddie, to go to the Lava Falls to rescue Sid from Rudy.
Roger was "commandeered" by Buck, Crash and Eddie in order to save Sid. During the attempt, they were attacked by Quetzacoatlus'. Roger was knocked out, but given mouth-to-mouth by Buck. They saved Sid, but accidentally flew into the ice ceiling above. They returned to the Plates of Woe, just in time to see the arrival of Peaches. When Buck asked Roger if he had ever thought of settling down and starting a family, the pteranodon gave him a weird look, then flew away.
