PELYCOSAUR Meaning and
Definition
-
A pelycosaur is an extinct reptile that belonged to a group of synapsids, or mammal-like reptiles, that flourished during the Late Paleozoic Era, specifically in the Pennsylvanian and Permian periods, approximately 318 million to 252 million years ago. The name "pelycosaur" is derived from the Greek words "pelys" meaning "wooden bowl" and "sauros" meaning "lizard" due to the shape of their skulls.
Pelycosaurs are characterized by their sprawling posture and reptilian features such as scaly skin, external fertilization, and egg-laying. They exhibited a wide range of sizes with some species growing up to the size of a small dinosaur. They were dominant terrestrial predators, feeding on a variety of vertebrates, insects, and plants. They possessed powerful jaws with sharp teeth and some had enlarged canine-like teeth for capturing prey. Pelycosaurs also had a sail-like structure composed of elongated spines on their back, which likely functioned in thermoregulation, sexual display, or both.
Pelycosaurs played a significant role in the evolution of terrestrial vertebrates as they were among the earliest reptiles to develop adaptations that foreshadowed mammalian characteristics. Their descendants eventually gave rise to more advanced synapsids known as therapsids, which eventually evolved into mammals. Pelycosaurs are considered important fossils for understanding the transition from reptilian ancestors to early mammalian forms and their diverse adaptations offer valuable insights into the evolutionary process during the Paleozoic Era.

Etymology of PELYCOSAUR
The word "pelycosaur" is derived from Greek roots. "Pelyco" comes from the Greek word "pelyx", which means "pelvis" or "basin". "Saur" is derived from the Greek word "sauros", which means "lizard" or "reptile". Therefore, "pelycosaur" essentially means "basin lizard" or "reptile with a pelvis". This term was coined to describe a group of extinct reptiles from the Paleozoic Era, which lived between 350 and 270 million years ago. Pelycosaurs were one of the earliest lineages of reptiles and are considered distant relatives of modern mammals.
