Uma, the fringe-toed lizard, enters the LRT

Uma is the extant fringe-toed lizard
(Fig. 1). This California desert specimen has a large orbit, much larger than the eyeball.

Uma inornata (Baird 1859) is the extant fringe-toed lizard, an insectivore. Flaps and interlocking scales prevent sand from entering the nose, mouth, eyes and ears. In the large reptile tree (LRT, 1707+ taxa) Uma nests with another desert lizard, Phrynosoma (Fig. 2). This clade nests with chameleons within the Iguania within the Squamata. No surprises here. Everyone agrees to this.

The addition of Uma to the LRT
and the few corrections made to scores in nearby taxa moved the following three former Early Cretaceous protosquamates to the squamates: Indrasaurus, Hoyalacerta, and Meyasaurus. These now nest basal to Yabeinosaurus within Scleroglossa. So generalized are these three taxa, they now also nest as sisters to the gekko + snakes and their ancestors clade.

This is how the LRT nests taxa
without bias, myth or tradition.
