Siberogekko progenitor
A second lineage of endothermic geckos has evolved by 200 million years in the future. These have been colloquially nicknamed “neosaurs”. Their filamentous pelage is derived from the epidermal scales present in squamates. This fuzz may be coarse or soft to the touch depending on species. Unlike the eublepharid geckos they are descended from, neosaurs do not eat their shed fuzz; it generally molts on its own, with old filaments being pushed out by new ones growing underneath. So far, they range in size from 20 cm to a little under a meter in length. They may seem humble in the Solanan period, but they are destined for great things to come.
Siberogekko is found in the coniferous forests of Eurasia. It is an agile and swift leaper, and adept at climbing trees. Its tail is prehensile and can help it grab branches, but it is not strong enough to support the entire weight of the body. Siberogekko eats insects, small mammals, smaller reptiles, and tastier plant parts. Individuals may associate with Avititan in a loose symbiosis; a Siberogekko will ride a “host” Avititan through the forest, and clean its skin of biting insects and bloodsucking nails on the way.
