No, it wasn't some hot new party drug, but rather, spironolactone, a prescription diuretic commonly used for people with high blood pressureâand sometimes prescribed to women with acne.
Almost all living organisms can leave fossils, but usually only the hard parts of plants and animals fossilize. Soft internal organs, muscle, and skin rapidly decay and are rarely preserved, but the bones and shells of animals are good candidates for fossilization.n this case, the fossil is a hole in the shape of the animal. By far the most common fossil remains are those of shelled invertebrate sea loving creatures such as snails, corrals, and clams. These make up most of the fossil record.
Types of Fossils. There are many ways fossils can form (don't worry, we'll get to that soon) but fossils can be divided into two main types: body fossils and trace fossils. The remains of a Hadrosaur are an examples of a body fossil, or fossils of the actual organism.Typically, hard structures like bones, shells and teeth fossilize more often than soft-bodied structures like tissues or plant leaves, but as is seen with the horsetail relative, plants can become fossils.ypes of Fossils.
