In 1930, Paul Ellenberger traced these images from a cave in Lesotho. The footprint was from an ornithopod dinosaur — which is still extant — that was in apparent association with three bird-like figure — which have now faded. Later in his career, Ellenberger interpreted the figures as Paleolithic speculative dinosaur reconstructions! The exact origins of the paintings are unknown, but apparently dinosaur fossils and trackways are numerous in the region and San peoples are well aware of them.
I’ll admit this subject matter is outside of my expertise, but if this interpretation is valid… then paleo-art has a much deeper history and extent across cultures than I’d ever imagined!

I should make it abundantly clear this should not be taken by anyone as “proof” of human-dinosaur co-existence (and Young Earth Creationism, Biblical literalism, yada yada yada…). If the footprint and figures were genuinely associated, it’s a clever reconstruction based on the available information. Ornithopod dinosaurs, despite the name, didn’t look like enormous birds.
