What does therapsid mean?
A therapsid refers to a type of mammal-like reptile that belonged to the group Synapsida. These animals lived during the Paleozoic and Mesozoic eras and exhibited a mix of reptilian and mammalian characteristics. Therapsids are significant in the study of vertebrate evolution, as they represent a key transitional phase between reptiles and mammals. They were characterized by their advanced dental structures, and some species had features such as hair, which is a characteristic typically associated with mammals. The study of therapsids provides valuable insights into the evolutionary history of mammals.

Etymology of therapsid
The term 'therapsid' originates from the Greek words 'therion', meaning 'beast', and 'apsis', meaning 'arch'. This refers to the animal's arch-like skull structure. The therapsids evolved from earlier synapsids during the Permian period, around 260 million years ago.
