Procolophonids are a group of small, herbivorous reptiles that lived during the late Paleozoic and early Mesozoic eras, approximately 260 to 200 million years ago. They belong to the order Parareptilia and are characterized by their robust bodies, short limbs, and distinctive skull shapes. Procolophonids were primarily terrestrial and are known for their adaptations to a plant-based diet. These reptiles are often found in fossil records across various regions, indicating a wide distribution. Their remains provide valuable insights into the evolution of early reptiles and their ecological roles during their time. Procolophonids are considered important for understanding the transition from the Paleozoic to the Mesozoic era.
