Caririchnium is an ichnogenus of ornithopod dinosaur footprint,[1] belonging to either derived iguanodonts or basal hadrosauroids.[2] It includes the species Caririchnium lotus from Lower Cretaceous Jiaguan Formation and C. protohadrosaurichnos from Upper Cretaceous Woodbine Formation.[3][4] Specimens are also known from the Lower Cretaceous El Castellar Formation and Camarillas Formations.[5]
The trackmaker was probably a large styracosternan related to Iguanodon.[5]
