The phylogenetic analysis in the paper (based mostly on Norman's basal
iguanodont chapter in Dinosauria II) places it as a basal
styracosternan in a trichotomy with Lurdusaurus and Hadrosauriformes
(Ouranosaurus, Iguanodon spp., and hadrosauroids).
The known elements are a mandible missing the predentary, isolated maxillary
and dentary teeth, cervical and dorsal verts, sternal
plates, ribs, and both pubes.
The generic name comes from Lanzhou (capital of Gansu Province), and of course
the trivial nomen means "big tooth". Individual teeth
are up to 75 mm wide and 140 mm tall. (It apprently didn't get the memo that
iguanodontians were increasing the number of tooth
positions, since it has only 14 dentary tooth positions).
Estimated length is 10 m, mass is about 5500 kg.
