In northeast Brazil, the capuchins have a food source limited to hard shelled fruits and seeds. As a survival adaptation they learned how to make use of the available sources by the use of stone tools. Interestingly enough, they don’t just use any old rock that they can find. The capuchins make sure that their “hammers” are the perfect size to swing with but are also made out of a hard enough material- such as quartzite. Sandstone is usually used as an anvil. The perfect tools don’t just go to waste after they are used, the capuchins make sure to stash these tools under trees so that they can be reused later on.
