Maclura pomifera

The osage orange is an interesting fruit not often talked about. It resembles a bright green tennis ball with convolusions like a brain. It is a heavy fleshy fruit that appears not to be eaten by any animal today. This is unusual as almost all large fleshy fruits' primary mode of seed dispersal is by consumption by large animals. One predominate theory today is that the osage orange fruit was eaten by a giant sloth that lived along side of the giant saber-toothed animals, all now extinct in North America.
