Diagnosis
ReferenceDiagnosis
P. S. Druckenmiller and A. P. Russell 2006Elasmosaurid plesiosaur possessing the following unique combination of character states: interclavicle rectangular with rounded corners and possessing a notch along either the anterior or posterior margin (orientation to be confirmed upon the discovery of articulated material); ventral ramus of scapula reaches midline but lacks a broad contact with its opposite; scapula with a prominent posteriorly directed prong extending toward the coracoid; well-developed midline contact between scapula and coracoid (pectoral bar) present in adult; presence of a well-developed anterior process of the coracoid along the midline, contributing extensively to the pectoral bar; coracoid of adult with a very prominent, ventrally extending midline process; cordiform intercoracoid vacuity fully enclosed posteriorly by coracoids; humerus with a pronounced postaxial accessory facet.
