• The skull is low, orbit medium-sized, dorsal profile of skull only weakly concave; premaxilla and dentary with well developed grooves extending in an alternating fashion from the fossa praemaxillaris and fossa dentalis; maxilla short anteriorly, not reaching far beyond external naris, taking part in the formation of external naris and ventral orbital margin, separating lacrimal and jugal; jugal robust and short, not extending beyond anterior orbital margin; squamosal large, forming most of the posterior margin of cheek region and reaching down to ventral margin of cheek, processus quadratus of quadratojugal thus apparently separated from main body of bone; prefrontal and postfrontal subequal in size; external naris large, of triangular shape; posterior maxillary dentition reduced; teeth robust and crenulated in typical fashion, without carinae; 44 presacral vertebrae, 88 preflexural vertebrae; postflexural segment of tail very long and flexible; neural arches of posterior thoracal region very low with expanded processus spinosi; rib articulations of thorax unicipital posteriorly; forefin with three primary digits, fourth digit postaxial, one accessory digit; third digit subdivided into 3 secondary rays; no notches in leading edge of forefin; digits of the forefin fanning out distally; most autopodial elements rounded and widely spaced; pelvis tripartite; ilium with anterior spine-like process; pubis slender and curved; ischium broad and subrectangular; hindfin tridactyl, most elements of first digit notched.
• It differs from modern teiids with the following traits: deep massively built dentary with heavy ornamentation below inferior alveolar foramina (at least in adults); A subdental shelf significantly deeper than in other primitive teiids with the maximum depth almost equaling the height of the anterior dentary teeth; Deep but narrow sulcus dentalis with the medial wall appressed close to tooth bases; Weak mandibular symphysis lacking robust ventral buttress; Heterodont dentary closely spaced and anteroposteriorly compressed, standing parallel to each other to form a comb like structure and obliquely to long axis of jaw; Slightly recurved crowns with unicuspid anteriorly and bicuspid posteriorly, with the main cusp in posterior position and anterior cusp smaller but prominent; strongly widened tooth bases transversely having thick ring like deposits of cementum; and subpleurodont tooth attachments with lateral parapets about half of the tooth height.
