Diagnosis
ReferenceDiagnosis
P. D. Mannion and A. Otero 2012Elaltitan can be diagnosed by an unique combination of character states, as well as one autapomorphy (marked by an asterisk): (1) spinopostzygapophyseal laminae in middle–posterior dorsal vertebrae bifurcate into medial and lateral branches; (2) dorsoventrally tall neural arch restricted to anterior half of centrum (excluding condylar ball) in anterior-most caudal vertebrae∗; (3) astragalar ascending process does not extend to the posterior margin of the astragalus; (4) presence of a calcaneum.
