Abstract The Triassic period stands as a crucial moment for understanding tetrapod evolution, marking the emergence and early diversification of numerous lineages that persist in today's ecosystems. Birds, crocodiles, testudines, lizards, mammals can all trace their origins to Triassic, which is distinguished by several adaptive radiation events fostered unparalleled diversity body plans lifestyles. Beyond this macroevolutionary significance, serves fertile ground scientific inquiry, especially studies. aim Special Issue assemble diverse array new contributions focused on continental tetrapods globally, encouraging collaboration among researchers across generations, pooling efforts comprehend pivotal evolutionary history. This issue encompasses almost 40 varied contributions, spanning topics from comparative functional anatomy, including descriptions novel taxa, comprehensive anatomical reviews, systematic investigations, phylogenetic analyses, paleoneurological studies, biomechanical assessments, detailed examinations histology ontogeny. Collectively, offers an extensive exploration anatomical, ecological, perspectives, unveiling fresh insights into intriguing vertebrate
