The interval was a time of intense diversification (an increase in the number of species) of marine animal life in what became known as the Ordovician radiation.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.

These give the softer corals some protection and support. Soft species also prefer to live in nutrient-rich waters with less intense light. In other parts of the world, fleshy true soft corals have no rigid internal skeleton at all. 3. Deep-Sea Corals.Types of Fossils. Fossilization can occur in many ways. Most fossils are preserved in one of five processes (Figure 11.6): preserved remains, permineralization, molds and casts, replacement, and compression. Preserved Remains. The rarest form of fossilization is the preservation of original skeletal material and even soft tissue. Most commonly found fossils can usually be classified to their group by observing some simple shapes and features. If your fossil has one of the shapes below, look down the …Exercise 6.2 – Identifying Types of Fossil Preservation. Inspect the first set of samples and fill out the table with information about the presence of original biologic material, positive and negative relief, and mineral composition of the samples. …Petoskey Stones: Petoskey stones are an extinct fossil coral that lived 380 million years ago.
