Need help identifying rock found on beach?
« on: 24/07/2011 04:36:55 »
Found this rock, or what I think is a rock, on the beach and dont know what it is. Very lightweight and slightly larger than a golf ball. Has the texture of fine grit sandpaper. It looks like it is made up of layers of fine metal mesh and the layers are peeling off.

Any help is greatly appreciated!

Paleozoic Fossils ...

Phylum Bryozoa (sea-mats, sea-mosses)

These colonial organisms are superficially similar to corals in that they have small tentacled bodies that live in cells inside a large skeletal structure. Bryozoan colonies have many forms, including ramose, or branching forms, palmate, or leaf-like forms, and glomerate, or globular forms, all of which resemble corals. There are also twig-like and fenestrate forms, which have a thin, open lattice of cells that looks like wire mesh, and there are encrusting forms that grow like lichen on the surface of another organism or object.

Your mesh thing fits the bill ...

Thanks for the response! Would have never thought it was a fossil. Thanks again for steering me in the right direction.
