THERAPSID Meaning and
Definition
-
Therapsid is a noun that refers to a member of a group of extinct mammal-like reptiles that lived during the Permian and Triassic periods. These ancient creatures are considered key transitional forms between reptiles and mammals, displaying characteristics of both groups. The term "therapsid" originates from the Greek words "thera," meaning wild beast, and "opsis," meaning appearance.
Therapsids, also known as "mammal-like reptiles," were highly diverse in terms of size, shape, and ecological adaptation. They ranged in size from small, shrew-like creatures to large, bear-sized predators. They had advanced jaw mechanisms, with teeth that were specialized for various functions, implying a varied diet encompassing herbivory, insectivory, and carnivory.
One of the key distinguishing features of therapsids is the presence of several mammalian traits. This includes the ability to produce milk, a secondary palate that allowed for breathing whilst eating, and a wide variety of limb structures that suggested different modes of locomotion. However, therapsids retained characteristics commonly associated with reptiles such as scaly skin, laying eggs, and having a more sprawling limb posture.
The evolution of therapsids and their subsequent extinction played a crucial role in the emergence and diversification of mammals. As a result, they occupy a significant position in our understanding of vertebrate evolution and the gradual transition from reptiles to mammals. Therapsids serve as an important link in the evolutionary chain, helping scientists gain insights into the origins and development of diverse mammalian features and adaptations.

Etymology of THERAPSID
The word "therapsid" is derived from Greek roots. It comes from combining the Greek words "thera" (θήρα), meaning "wild animal" or "beast", and "opsis" (ὄψις), meaning "appearance" or "face". Therefore, "therapsid" can be roughly translated to mean "beast-like" or "wild animal-like".
The term "therapsid" was first coined in the early 20th century by South African paleontologist Robert Broom to classify a group of mammal-like reptiles that existed during the Permian and Triassic periods. These reptiles were characterized by their mammal-like teeth, as well as other anatomical features related to their feeding habits. The word "therapsid" is still used today to refer to this group of extinct reptiles.
