This article is about the Squamata order of reptiles. For the Roman scale armour see: Lorica squamata.

Squamata (scaled reptiles) is the largest recent order of reptiles, including lizards and snakes. Members of the order are distinguished by their skins, which bear horny scales or shields. They also possess movable quadrate bones, making it possible to move the upper jaw relative to the braincase. This is particularly visible in snakes, which are able to detach their jaws entirely to accommodate very large prey items. The male members of the group Squamata are the only vertebrates with a hemipenis. This is also the only reptile group where we can find both viviparous and ovoviviparous species, as well as the usual oviparous reptiles. Roman scale armour fragment. ...

Classically, the order is divided into three suborders:

Palaeos Vertebrates 240.000  Squamata Overview (379 words)
The Squamata are the most successful order of Cenozoic reptiles, with some six thousands recent species (more species than there are mammals!).
Technically, the Squamata are lepidosaurs, distinguished from other related and similar forms by a flexible and powerful jaw structure.
This came about through the loss of the lower temporal bar in the skull, which gave more room for the jaw muscles to develop, and the development of a special moveable hinge, the quadratojugal hinge, between the quadrate and squamosal bones in the skull.
