What is this found on a local beach?

[Archimedes]

I suspect it's something extraordinarily dull, but my nephew found this and wants to know what it is.

The little pods or what ever they are were about 1/2 to 1 inch long. We found a few bunches of them, typically attached to pebbles and shells. He fancies it something exotic like eggs of some sort but I haven't a clue what they are.

Anyone know?

Why would eggs be exotic? They look either like some aquatic type of eggs; or some sort of mushrooms. The latter don't really make sense for the location though.

Turtle turd.

My best guess would be the settling or juvenile phase of a mollusk, possibly a variety of barnacle.

I agree... They are barnacles.

It is hard to tell from that image, but it looks like a colony of sea squirts (tunicates, Urochordata).

Sea squirts. Doing some Googling of images of sea squirts there's some that match exactly what I found. Thanks Peez!
