PARIETAL: overall aspect rounded in dorsal view, as long as broad, with anterior margins concave or straight contacting frontals; lateral ridges visible in dorsal view, extending up to region of contact with supraoccipital; lateral ridges not touching each other; anteriormost portion contacts frontals lateroventrally and parabasisphenoid ventrally; rearmost portion of parietals contacts prootic and supratemporal posterolaterally. POSTORBITALS: shape rearward portion of orbital cavity and have no contact with frontals; straight in lateral view, with no ventral curvature and not approaching region of contact between ectopterygoid and maxilla. SUPRAOCCIPITAL: dorsally contacts parietal anteriorly through curved suture; supratemporal and prootic laterally, and exoccipital posteriorly; mesoanterior portion undergoes constriction relative to lateral regions; posterolateral region with two conspicuous and oblique ridges towards supratemporals; among these side crests emerges a rather pronounced medial ridge, restricted to posterior portion of supraoccipital, occasionally touching exoccipitals; this region shows a depression relative to anteriormost portion of supraoccipital. EXOCCIPITALS: irregular shape in dorsal view, showing medial constriction and two lateral ridges corresponding to maintenance of posterolateral ridges of supraoccipital; medially exoccipitals may show a rather conspicuous ridge representing maintenance of medial supraoccipital ridge; exoccipitals contact basioccipital ventrally and prootic in lateral surface, where is situated

PARABASISPHENOID COMPLEX: spear shaped, with rear end broader than anterior portion tapering from the level of contact between ectopterygoid and maxilla; contacts basioccipital posteriorly, prootic and parietal posterodorsally, frontal dorsoanteriorly, and choanal process of palatine anteroventrally; posterior Vidian foramen near sutures with prootic and parietal in posterolateral region; basisphenoid with medial ridge, more conspicuous on the level of posterior boundary of orbital cavity. MAXILLAE: arched towards premaxilla in dorsal view, with a slight lateral twist on the level between prefrontal and ectopterygoid; laterally maxilla corresponds to inferior border of orbital cavity, extending from the level of premaxillary vomerine processes up to the level of postorbital, when contacts ectopterygoid; maxilla corresponds to more than half of length of braincase; ventral surface with 31˗35 subequal, curved, and rear facing teeth, with posterior teeth slightly larger and having no diastema; palatine process situated in first third of maxilla and completely covered by prefrontal; ectopterygoid process situated posteriorly. ECTOPTERYGOIDS: narrow, slightly curved, with anterior end in half moon shape, superimposed on ectopterygoid process of maxilla; rear end contacting dorsolateral portion of pterygoid. PTERYGOIDS: elongated, corresponding approximately to half size of braincase; ventral surface with 33–37 subequal teeth; anterior portion tapered contacting palatine and gradually widening from the region of contact with ectopterygoid in anteroposterior direction; pterygoids nearly parallel along its length, except in rear end, at the end of tooth line, from which pterygoids taper again and move apart until contact quadrate dorsolaterally. PALATINES: slender, straight, slightly shorter than length of dentary; ventral surface with 20–23 subequal teeth; choanal process of palatine medially directed towards parabasisphenoid, contacting small portion of ventromedial face of prefrontal; anterolateral process contacts palatine process of maxilla; in dorsal view, forked rear end contacts pterygoid, with medial branch longer than lateral branch; palatine contacts pterygoid approximately at the level of ectopterygoid process of maxilla.

; ventral portion contacts glenoid cavity of retroarticular process of mandible; ventromedial portion contacts rear end of pterygoid; quadrate tapers dorsoventrally. DENTARIES: anterior end curved towards opposite hemimandible; lateral face convex with mentonian foramen medially located; after this foramen, dentary branches into dorsal (longer) and ventral processes; dorsal surface with 32–36 conical rear facing teeth. SPLENIALS: tapered anteriorly, in the region of contact with dentary; anterior mylohyoid foramen limited by angular. ANGULARS: elongated, triangular, tapered posteriorly, contacting dentary anterodorsally and splenial anteroventrally; posterior mylohyoid foramen near suture with splenial; angular˗splenial joint visible in ventral view. COMPOUND BONE: correspond approximately to three-quarters of mandible; surangular crest with rounded dorsal edge and lower than prearticular crest; in lateral view, compound bone tapers anteriorly, fitting between dorsal and ventral processes of dentary; posterior foramen of surangular exposed.
