And no, it's not the birth control pill. Here, you have to try this, my friend Nancy said, sliding a yellow tablet to me across her bathroom vanity. 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.
When most people think of fossils they think of dinosaur skeletons and large bones, but there are many different types of fossils to be found. Palaeontologists, people who study fossils, divide them into two major types-body fossils and trace fossils.Body fossils show us what a plant or animal looked like. The first type, body fossils, are the fossilised remains of an animal or plant, like bones, shells and leaves.he second type of fossil records the activity of an animal. Known as trace fossils, these include footprints, trackways, and coprolites (fossil poo!). Footprints and coprolites are trace fossils-they show us how an animal lived. There are lots of different types of fossil.
