Attack of the Killer Bunya Pines

I was in Aquatic Park the other day when I saw this gem:

The tree is Araucaria bidwillii, otherwise known as a bunya pine.  The tree produces male pollen cones and female seed cones.  The female seed cones can get up to a foot in diameter.  In the fall Araucaria bidwillii apparently uses the seed cones to crush hapless passersby.
