Diagnosis
ReferenceDiagnosis
H. You et al. 2005Lanzhousaurus magnidens is different from all other iguanodontians in possessing large individual teeth and a small tooth count per tooth row, with a mere 14, but ～4 cm-wide, tooth families preserved in a single dentary tooth row.
G. S. Paul 2008*Adults gigantic. Overall massively constructed. Dentary pre-coronoid process length/minimum depth ratio under 5, diastema absent. Teeth *extremely large, maximum tooth positions *14 in dentary, one tooth in each position. Dorsal neural spines moderately tall, *modest withers present. Prepubic process of pubis deep.
