You, 2005 w abstrakcie pisze:Lanzhousaurus magnidens is an iguanodontian dinosaur recently discovered in the Lower
Cretaceous Hekou Group of Gansu Province, northwestern China, which possesses the
largest teeth of any herbivorous dinosaur yet discovered. The holotype is represented by a
partial skeleton of a single individual including the mandible (missing predentary, right
coronoid and right articular), isolated maxillary teeth, isolated right and complete, in situ
left dentary teeth, a series of fourteen vertebrae (six cervicals and eight dorsals), both sternal
plates, ribs, and both pubes.
Lanzhousaurus differs from all other iguanodontians in possessing large individual teeth
and a small tooth count per tooth row, with a mere 14 ~4 cm-wide tooth families preserved
in a single dentary tooth row of the 1 m long lower jaw. Based on a cladistic analysis,
Lanzhousaurus is firmly situated as a member of the Styracosterna by virtue of a suite of
derived features, such as the relatively narrow, lozenge-shaped maxillary teeth with mammilliform
marginal denticles, hatchet-shaped sternal plates, and pubis with expanded cranial
blade and short caudal ramus. Among members of the Styracosterna, the closest taxon
to Lanzhousaurus is the Nigerian iguanodontian Lurdusaurus, and they together may represent
a previously unrecognized, massively-constructed quadrupedal lineage in the evolution
of ornithopod dinosaurs. Both Lanzhousaurus and Lurdusaurus are less derived than the
Iguanodontoidea, which evolved derived features such as more than 20 teeth per tooth row,
one or two prominent ridges on the dentary crown, and closely appressed metacarpals II-IV.
