Eureptilessuch

Eureptilessuch is a proposed clade of diapsid reptiles that encompasses all extant reptiles and birds, excluding snakes and turtles. This grouping is based on morphological and molecular evidence, suggesting a common ancestor for this diverse set of animals. The name "eureptilessuch" is derived from Greek and Latin roots, meaning "true reptiles" and "crocodile," respectively, hinting at its intended scope. Within this classification, crocodiles and birds are often placed as a sister group to lizards and amphisbaenians, indicating their close evolutionary relationship. The inclusion of birds within a reptilian lineage is a significant point of eureptilessuch, as it reflects the current scientific understanding of avian evolution originating from theropod dinosaurs. This classification aims to create a more monophyletic grouping of reptiles, meaning it includes an ancestor and all of its descendants. However, the precise composition and validity of eureptilessuch are still subjects of ongoing research and debate within the scientific community. Alternative classifications exist, and the field of reptile phylogeny is dynamic.
