Emended diagnosis (modified after Brinkmann 2004; Jiang et al. 2006; Liu 2011; Ji et al. 2016; and Renesto et al. 2020).—Centrum height/length ratio moderately increased in the mid-caudal region, but not exceeding a value of 3.0 centrum height/length index significantly increased in the mid-caudal region to a value of over 3.0 in Phalarodon ); interclavicle T-shaped with transversal bars perpendicular to the posterior process (interclavicle V-shaped, with posterior process triangular and broad, and transversal bars triangular, narrow and projecting anterolaterally in Phalarodon ); humerus relatively broad with proximodistal length subequal to anteroposterior width (humerus narrow, proximodistally longer than anteroposteriorly wide in Phalarodon ).
