Ginkgo fruit is known for its notoriously bad smell. The outer part of the seed produces the unpleasant odor. It is likely that at some point in history, this characteristic evolved to attract animals to eat and disperse its seeds, but today, it is not known to attract wildlife. Ginkgo seed dispersal remains somewhat of a mystery. It is possible that its animal pollinators are extinct; however, the seeds do have a significant amount of nutruients, which could attract squirrels. The fruit is fleshy, tan or orange-colored, and ovular.
