Dimetrodon’s sail has sparked debate ever since its discovery in the 1870s by Edward Drinker Cope. Earlier interpretations of the sail suggested it was used to regulate Dimetrodon’s body temperature by absorbing heat. However, more recent studies suggest it may have been poorly suited for such a task. Scientists now believe it may have been used for display purposes, to attract mates, and it may have had intricate, brightly colored patterns to achieve this purpose.
