While digging some very old gastropods and bivalves out of some sandstone boulders, I came across what looks like some sort of marine worms. Did some prehistoric marine worms have calcium shells?

Time is like a sharp It can carve hard lines on beautiful faces and wear out youth year after year, but using it well can make a piece of simple stone into a great statue. St. Mary Academy is still a simple piece of white stone briefly carved, but as time marches on, it may be spoiled by dust, worn out by weather, or broken into separate pieces. It may be also carefully carved by knife into wonderful statues. Everyone at school, including our schoolmates, controls this knife.
