The Ica stones are a collection of andesite stones from the Ica Province in Peru, known for their engraved motifs. Largely regarded to be modern hoaxes, the stones in some cases utilize art styles from various pre-Columbian Peruvian civilizations and often depict anachronistic scenes or objects, including dinosaurs and advanced technology.

Human–dinosaur coexistence
The coexistence of avian dinosaurs (birds) and humans is well established historically and in modern times. The coexistence of non-avian dinosaurs and humans exists only as a recurring motif in speculative fiction, because in the real world non-avian dinosaurs have at no point coexisted with humans.
