Caririchnium liucixini

† Caririchnium liucixini is a large ornithopod ichnogenus from the Early Cretaceous of China. The three-toed, broad footprints record the passage of sizeable iguanodontian dinosaurs across Cretaceous substrates of East Asia. Named in honor of Chinese researcher Liu Cixin, these tracks contribute to a growing body of ichnological evidence for the diversity and distribution of large herbivorous dinosaurs across Early Cretaceous Asia, a region that served as a major cradle of dinosaurian evolution.

Diet & Feeding

Herbivore

Caririchnium liucixini was a plant-eating dinosaur. Herbivores typically fed on ferns, cycads, conifers, and other vegetation available during their era. Many herbivorous dinosaurs developed specialized teeth and digestive systems for processing tough plant material.

Time Period

Cretaceous Early Mesozoic Era

Caririchnium liucixini lived during the Cretaceous Early period of the Mesozoic Era, approximately 145.0 to 100.5 million years ago.

The Cretaceous saw continued dinosaur evolution with the rise of ornithopods and early ceratopsians. Flowering plants first appeared and began to transform terrestrial ecosystems. Spinosaurus and other large theropods lived during this time.
