Skeletal mount of Hypacrosaurus altispinus, copyright Roland Tanglao.


Belongs within: Hadrosauroidea.
Contains: Hadrosaurinae.

The Hadrosauridae are a group of large herbivorous dinosaurs known from the Late Cretaceous of Eurasia and North and South America, recognised by Horner et al. (2004) as the least inclusive clade containing Telmatosaurus and Parasaurolophus.

Characters (from Horner et al. 2004): Three or more replacement teeth present per tooth family; dentary tooth row extending distally to terminate caudal to apex of coronoid process, caudalmost termination of dentary well behind coronoid process; surangular foramen absent; ectopterygoid and jugal not in contact; supraorbital absent or fused to orbit rim; neural arches with cervical zygapophyseal peduncles elevated to extend well above level of neural canal; postzygapophyses long, dorsally arched; coracoid bearing long cranioventral process extending well below glenoid; proximal scapula dorsoventrally narrow, with acromion process projecting horizontally, notched cranioventral corner, reduced area for coracoid articulation; femur bearing deep intercondylar extensor groove, with edges meeting or nearly meeting cranially to enclose extensor tunnel.
