wish I had a good photo of the shells down in mexico...there are some that look just like that first pic (I thought they were cones, but it is certainly possible that I am wrong...) we were supposed to go down to the cabin next week, but then trouble appeared on the horizon, and it seems we won't... :frown:

It is possible it is a high spired snail shell. That is really thick shell in spots though. :?


The orange rind on the rocks in some layers of this formation are considered to be bacterial or algal mats, maybe this is just one of the above mentioned animals with a layer of growth on it :?: :?: :?:

Well, the general concensus on the other list is that it is a nautiloid cephalopod with silicified deposits in the siphuncle and camerae.

:roll: Who would have thought...
