The structure of the
skull of
Slavoia suggests that it may have had a
fossorial (burrowing) lifestyle, and when fully grown, it likely grew up to long.
Slavoia is known from several specimens including the holotype ZPAL MgR-I/8, mostly made up of incomplete skulls and skeletons, and it has therefore been possible to reconstruct its appearance.
Slavoia is characterized by a skull with a very compact structure, and the orbits were small, the parietal hole was small or non-existent. The teeth, pleurodonts, were robust. The premaxilla had five teeth, while the maxilla and jaw had seven or eight. The lacrimal bone was greatly reduced, and there were 26 presacral vertebrae, equipped with an anteriorly hollow vertebral centre (procelus). Relative to most lizards, the limbs were relatively small, and the body was elongated, suggested to be adaptations for a burrowing lifestyle. The first
digit of the hand had hyperphalangy (the presence of additional
phalange bones). == Classification ==
