Diagnosis
ReferenceDiagnosis
E. M. Gomani 2005Malawisaurus is characterized by high-angled premaxillae; posteriorly broad, angled infratemporal fenestrae; short and divergent basipterygoid processes; dentary with 15 alveoli that extend two thirds the length of the element; thin splenial with a spenial foramen; broad but not spoon-shaped teeth with high-angled wear facets; undivided cervical neural spines and pleurocoels; cervical prezygapophyses extend beyond the anterior end of the centrum; presence of pre- and post-spinal laminae in distal cervicals; ribs in proximal and middle cervicals extend beyond the end of the succeeding centrum; elongate, eye-shaped pleurocoels on dorsal vertebrae; infradiapophyseal laminae of distal dorsals not forked; six sacral vertebrae; sacral neural spines fused into a dorsal plate that overhangs the neural arches; strongly procoelous proximal but platycoelous middle and distal caudals; proximal caudals with well-developed pre-spinal and post-spinal laminae; at least five V-shaped middle chevrons; and metacarpals with distal articular facets.
