Pterodactyl Poo

This was on my car when I came out of Jenna's ballet exam this morning.
Hamish and I examined it closely.

Given we were not parked under a tree, I decided it must have been a very large bird to fly and launch it because there is a large amount of matter in this baby.  (pictured with a AA battery for size comparison....)

The only thing we could come up with is, it had to have been a Pterodactyl.  Granted they haven't been sighted in a few million years, but what other flying creature could have done this.  It wasn't a sparrow, we don't live anywhere near the coast, ducks aren't flying around at the mo, and it wasn't in the country.

Hamish likes the idea of it being a pterodactyl too.....
