Captorhinidlik is a term used in paleontology to refer to the evolutionary radiation and diversification of Captorhinidae, an extinct family of anapsid reptiles that lived during the Permian and Triassic periods. These reptiles are among the earliest known diapsids and are characterized by their tooth-filled jaws, a trait that likely aided in their herbivorous or omnivorous diet. The fossil record reveals a variety of captorhinid forms, differing in size, skull structure, and tooth morphology, suggesting adaptation to different ecological niches.

The study of captorhinidlik involves examining their skeletal anatomy, particularly their skulls and teeth, to understand their phylogenetic relationships and evolutionary history. Researchers analyze the unique arrangements of their skull bones and the patterns of their dental replacement to infer their diets and lifestyles. The geographical distribution of captorhinid fossils, found across North America, Europe, and Asia, indicates a widespread presence during their existence.

The success of captorhinids can be attributed to their successful adaptation to terrestrial environments during a period of significant environmental change. Their anapsid skull condition, lacking temporal fenestrae, is a primitive feature that distinguishes them from later diapsid groups. Understanding captorhinidlik provides valuable insights into the early evolution of reptiles and the diversification of vertebrate life following the Permian-Triassic extinction event. Their extinction is thought to have occurred by the end of the Triassic, making way for the dominance of other reptilian groups.
