so many caves and channels and tunnels and ridges and... lots going on there, I kept going back for another look! interesting about the boring clams, at what point in the coral's life would that have happened... since it was fossilized? I have to go look up boring clams now!!!

I have to go look up boring clams now!!! snowmom, I believe coral boring clams still exist today. Much of the coral I find has those holes from those clams. And many of them that have those weird cavities were attacked by the clams. It may have effected the way they silicify; I think those clams can kill the coral. That coral sits on limestone bed rock from an older ocean. But sitting on top of the limestone bed rock seems to be a thin layer of silicified limestone(chert I suppose) between the coral and the limestone. It can be 1-5 inches thick. This is a slab of it. Notice how many clams stopped when they drilled thru the coral and hit this base material. Suppose they put it in reverse when there was no polyps to feed on and went back to the top to start another hole.

interesting! Do you ever find fossil shells from those clams? bet their shells are super hard from all the calcium they had to eat. I have seen sea shells with bore holes (not fossils) but those holes are HUGE... the clams that made them must have been lulus!

Superb show. Are those pieces cooked already or straight from the source?

I do find an occasional oyster with the coral, and other parts of some clam, and it may be the boring clam. The holes you find in sea shells are from sponges of all things. Silicified oyster with holes on right found with the also shallow water loving coral. The oysters w/holes look good tumbled

The creek in the last photos is also about a mile away from the river, at a higher altitude. It is full of shallow water fossils like oysters, a few corals, urchins, pet mangrove tree and an occasional pet palm. The oysters w/red in them were cooked at 600F in the kiln in one of the photos. Houses close to the river are 3 stories up on stilts. www.flickr.com/photos/67205364@N06/sets/72157633247311699

Very Cool! Do you ever find other fossils like shark teeth and bones in the river?

loved the pics.. plenty of color and variety. You find the best stuff! Houses on stilts... River living must take some great compromising, I surely understand that to many folks, it's well worth playing by the river's rules, just to be close to her. thanks JamesP!

Very Cool! Do you ever find other fossils like shark teeth and bones in the river? Never found a shark's tooth. Found bones once. And have a friend from Florida that finds bones and teeth all over Florida and can not explain why there is not bones and teeth at the Withlacoochee. He collects coral there a good bit. We collect in the Santa Fe and bones are everywhere and a few 45 miles south in the Suwannee. The bone capital is the Peace River in SW central Florida. Shark's teeth all over FL. But the lack of other bones at the Withlacoochee is probably due to high acid clays washed down from Georgia. Fossils a mystery.

Superb show. Are those pieces cooked already or straight from the source? They are not heated Kurt. Those hollow ones were imbedded in white clay and rarely change color. The ones with orange botryoids turn black.

Great to see and had never even though about what clams would do. Very interesting.
