Rare Primitive Reptile
Captorhinus magnus
Permian
Arroyo Formation, Lawton, Oklahoma

Captorhinus magnus was one of the very first reptiles that laid its eggs on dry land and was an early ancestor of synapsids and other reptiles. Known as a stem reptile, other reptiles and mammal-like reptiles branched off from it. Eventually, one of these branches evolved into the Archosaurs that survived the Permian extinction and gave rise to the dinosaurs much later. This impressive mounted specimen is a composite of several individuals, as are all mounted Captorhinus skeletons. The detail is excellent, particularly the large, formidable 3 x 2 ½-inch skull which has been prepared open to show the rows of tiny sharp teeth and the mysterious small round hole in the center (which, paleontologist speculate, may have allowed sunlight to reach the pineal gland.) Another feature of the preparation is that the ribs have been cemented to the matrix adding stability to the very delicate bones, yet maintaining a very natural appearance, evoking a crawling movement over the matrix. Approximately 15 percent restoration, primarily on the ribs and delicate spines. Mounted on black matrix. Matrix measures 20 x 11in; Specimen measures 18in
