4 Silurian Brachiopods. These brachiopods from the Silurian are quite rare, but they still can be found. They were as yet uncommon in the ancient Silurian Seas. Corals are cone shaped marine animals that held the creature called a polyp. They are found in Silurian through Middle and Upper Paleozoic marine rocks around the world and corals still exist in the oceans today though they have changed. Coral reefs grew and became places for other animals to hide. Because of the coral reefs we are able to see what life was like so long ago.
The Rochester Shale Formation is famous for the fossils found there. Because of the fine grained shale the preservation is great. It was formed during the Silurian Period when that part of New York State was a shallow salt water tropical sea and teeming with life. Because it was near the equator and prone to storms fossil formation was easy. The storms would stir up the ocean floor but also the storms moved on to land. The storms would disrupt the life and damage the animals.
Sometimes animals could escape but not the ones attached to bryozoan colonies or rocks on the sea floor. Corals and other creatures could not escape. The storm picked up sand and mud which then washed into the shallow seas and lagoons covering the animal. These 4 Silurian Brachiopods became trapped in the mud. The animals died and begin to turn into fossils. Because of the fine mud that covered them they have great detail.
