Leptopleuron lacertinum

 
Leptopleuron was part of the family Procolophonidae; a group of small parareptiles that were abundant throughout the Late Permian to the Late Triassic Period living in what is now Europe, North America, Africa and perhaps Antarctica. Remains of Leptopleuron have been dated to the Upper Triassic (Norian) and are only known from the Lossiemouth Sandstone Formation of Scotland; it shared similar characteristics with the skull and mandible of Hypsognathus from New Jersey, North America of which Leptopleuron was closely related. Most of the material of Leptopleuron is represented by natural molds in sandstones; it would have been ‘armored’ and lived in the dry lands of the Triassic, it may have been strictly herbivorous although earlier procolophonids were insectivorous.
