Diagnosis
ReferenceDiagnosis
M. T. Young et al. 2010Metriorhynchid thalattosuchian with over 20 teeth per maxilla, and more than 20 teeth per dentary; variable ornamentation on the cranial bones, but lacking conspicuous ornamentation on the rostrum; the antorbital fossa is elongate, narrow, and oriented obliquely, and is enclosed by the lacrimal, maxilla, and jugal; the antorbital pseudofenestra is enclosed by the lacrimal, nasal, and maxilla; the internal nares opens out posteriorly into the buccal cavity, with the palatines creating a V-shape with its apex directed anteriorly; the maxilla–palatine suture forms an M-shape orientated posteriorly; the squamosal contributes at least 50% to the supratemporal arch; the length of the cervical centrum is shorter than its height; the tibia is roughly one third of the length of the femur; the atlas hypocentrum is subequal in length to the odontoid process length; the humerus is subequal in length to the scapula.
