Fishtail projectile point

Fishtail points, also known as Fell points, are a style of Paleoindian projectile point widespread across much of South America at the end of the Late Pleistocene, around 13-12,000 years ago. They are thought to have been multifunctional, serving as cutting tools, as well as hafted to spears to use as hunting weapons, possibly in combination with spear throwers. Fishtail points have been found in association with extinct Pleistocene megafauna, such as the equine Hippidion, and it has been argued that hunting using these points may have been a factor in their extinction.
