The people of Mesoamerica had discovered dinosaur bones, but they thought that the bones were the bones of giants. This account is from Bernal Diaz, a soldier who fought with Cortes in conquering the Aztecs: "The Aztecs said that their ancestors told them that a long time ago there were settlements of men and women who were very tall with huge bones; that because they were very evil and of bad behavior, they killed them fighting with them, and those remaining died. And in order that we could see what enormous bodies they had, they brought a leg bone of one of them, and it was very heavy and very large in height compared to a man of average stature. And that leg bone was from the knee to the hip. I measured myself with it and it was as tall as I, although I am of average height. And they brought other bones like the first. Most were already bare and hardened from the earth, and all of us marveled at seeing those leg bones, and we were certain that there had been giants in this country. And our Captain Cortes told us that he would be sending that great bone to Spain in order that His Majesty could see it, and so thus we sent it with the first products that went out."
