Caririchnium is an ichnogenus of ornithopod dinosaur footprint, belonging to either derived iguanodonts or basal hadrosauroids. It includes the species Caririchnium lotus from Lower Cretaceous Jiaguan Formation and C. protohadrosaurichnos from Upper Cretaceous Woodbine Formation. Specimens are also known from the Lower Cretaceous El Castellar Formation and Camarillas Formations.

Caririchnium leonardii - dinosaur track from the Cretaceous of Colorado, USA. (replica; public display, Red Rocks Amphitheater visitor center, west of Denver, Colorado, USA) Dinosaur Ridge, Colorado has numerous dinosaur fossils, including bones and tracks. The most common track type at the site is Caririchnium leonardii, which was made by an iguanodontid dinosaur. The large, wide, three-toed print was produced by a hindfoot.
