Some 33,000 Acámbaro figurines (left) and 15,000 Ica stones, which were dug up last century, were probably (and arguably) buried around the time that the dinosaurs went extinct, providing solid evidence that our giant ancestors once had to contend with dinosaurs. The three Ica stones in the picture show not just a human with a dinosaur but also an ancient astronomer and an advanced medical procedure. The lower photo was taken in the Berlin Museum of Natural History (Museum für Naturkunde). Note the relative size difference between humans and dinosaurs then and now.
