Hrm....sponge or wasp/bee nest
« on: 24/08/2008 23:31:54 »
Hello all. Long time reader, first time poster. I'm hoping the very knowledgeable folks on this forum might be able to help me identify this fossil. I found this in a creek bed in Central Missouri. Any help would be greatly appreciated. Many many thanks in return.

This TNS thread on coral may be of interest...

A scale in a picture would help (a picture with a ruler in it - or a quarter or a dime.)

Baring that, I would say coral if the cells are larger than an inch.

Most of the cells are 1/4 inch wide. Sorry about the previous pictures. I should have included the scale for reference.

Top light colored one looks like a wasp nest from that angle, but looking at the outer surface Its not quite right... but it looks old!

Here is a paper wasps nest!

Its really hard to tell as the pieces seem very old.. it could be a wasp nest.. Maybe.. I am no expert  though and someone should know better then I.

If you compare the size of the hexagonal cells with the thickness of the walls separating them...

The walls in your fossil are too thick for an insect nest, (paper nest left, wax comb right).

I think your fossils are coral.

All of the pictures are of the same specimen. Some pictures were taken with a flash...others not.
Thank you all for your suggestions. Much appreciated. :)
