What’s this black hollow irregular egg-ish rock-shaped object?

    I found this in Seattle’s Lake Union while paddle boarding. It was floating on the water. I pressed lightly and it was broken just like an egg. That’s when I realized it was hollow inside, empty with white dots on the shell (like a bacteria block/mildew). Also on the surface, there’s a small area different from the rest (like the chestnut).

    I’m thinking maybe a buckeye that fell into the lake

    It looks like a similar material to a shark egg but less cool in the shape department

    I agree with hollowed out buckeye. You’ll find them on land like that as well; the inside decomposes quicker than the outside shell.
