6_Ichthyosaur-Summary_figure_2 (IMAGE) Natural History Museum of Los Angeles County Caption A figure from the text comparing "C. youngorum" to a modern sperm whale as well as rates of body size evolution over time between ichthyosaurs and cetaceans. The lines trending towards the top indicate larger body sizes whereas those towards the bottom are smaller sizes. Time is displayed as starting from the point of origin of the group until their extinction (for ichthyosaurs) or present (for whales).
