This diverse, speciose group – no less than 8000 species in our timeline, maybe a hundred more in Spec – includes the tuataras, "lizards" (geckos, skinks, thorn lizards, true lizards, zallingersaurs and glyphons, iguanas, agamas, chameleons, monitor lizards, slow-worms, Gila monsters, and so on), mosasaurs, and snakes. Spec is home to practically all the squamate groups of Earth, in addition to some oddball species that have gone extinct in our timeline, most notably the mosasaurs, the madtsoiid snakes, and the polyglyphanodontid lizards.
