The fossil coral has many bore holes from 1/4 to 2 inches in diameter. Two genus of thin shell clams do the drilling-Lithophaga and Gastrochaena These stone eating clams use gastro juice to dissolve the deep holes, clever. They still exist today, feeding on the live polyps in coral. A thin shelled lithophaga or date clam The danger of a litophaga clam living near Boston Fossil evidence

I have finally found what kind of critter can kill a mighty coral reef. Ends up being a wimpy thin shelled clam w/a bad ass stomach. i was hoping for diamond teeth and some kind of alien auger. Nature is clever Michael. Never underestimate the power of stomach acid !!

About all the coral I find is at 100 feet above sea level snowmom. Mostly in rivers where the river has exposed them. On a recent trip I sat at the computer one evening and found creeks that flowed under the interstate at roughly the 100 foot altitude. So that I could pull off the interstate on the way home and walk up the creeks and see if coral was to be found. I was successful. And happy, as the more locations to collect the better. It creates a difference in what they(the scientists) claim was the depth of the ancient ocean is though. This coral being shallow water coral... The coral is never found at 120 or 140, just at about 100. They say 200 was the ancient depth. So I am a bit curious why there is a difference. Not that it is a big concern, as I am just trying to collect a variety of different coral. But the coral is telling us a story. Perhaps tectonic activity occurred. Well enough. I will take their word for it. One day I will pose the question. curious to their reply.
