The new Paleozoic fauna created by the “Ordovician radiation” dominated the seas for the next 230 million years. Pandemic species of planktonic graptolites and conodontes appear in the fossil record during this Period. Crinoid fossils are most commonly found as "columnals," pieces of the stalk that hold the head (calyx) above the surface. The calyx and the holdfast are only occasionally preserved as fossils. Crinoids are still around today; those in shallow water are mostly stalkless, while those with stalks are restricted to deep water.

Articulate brachiopods are often the most common fossil brachiopods. They have two valves, the larger is the pedicle valve. The pedicle foramen is a hole towards the end of the pedicle valve (Figures 2, 4A, 4D, 4E). The valves articulate by teeth on the pedicle valve that fit into sockets on the brachial valve, giving them the nameThey are either body fossils or trace fossils of marine invertebrates. Most of the diversity comes from corals and brachiopods. In terms of abundance, crinoid columnals (pieces of the “stems” of sea lilies) are frequently found, but columnals are hard to attribute to species so we know very little about the actual kinds of crinoids that ...Fossil watches are made in China and Switzerland.
