Whose egg in my mulch?

Hi. While planting flowers in a mulchy area, I found an egg. Just one, oblong, probably a bit longer than 2", off-white with brown speckles. I put it back in the mulch but am curious what it might be. The area is not far from a small creek, so I'm thinking a turtle.

The most likely suspect would be a painted turtle egg. This time of year, females are busy laying eggs and can travel quite a distance from their pond to lay eggs.

Thanks for your question!
