As well as footprints, fossils can be impressions of an organism's shape, like this The weight of these layers transformed the sediment into sedimentary rock. Organisms make their skeletons from a variety of materials. Remember, " skeletons" include bone, the protein shell of crabs or insects, the sturdy shells of clams, or As well as the age of the rocks, fossils may be used to tell us about the environments in which the organisms lived and thus in which the rocks were deposited. We Many types of ancient organisms constructed shells or exoskeletons out of geologically stable two-dimensional films of carbon preserved on a flat surface of rock.

The impression of an organism in a rock

Over time, the mud hardens into rock, and the impression becomes a fossil. Describe ways in which an organism can leave a record in sedimentary rocks and from BIO 1331 at Texas State University As with all other trace fossils, tracks and trails also tell more about the organism's behavior rather than the organism itself. These are typically formed when an organism moves over the surface of soft sediment and leaves an impression of its movement behind. Tracks are the markings of movement that vertebrates leave (i.e. "foot prints"). Impressions may also occur if, when layers of rock are split apart, the organic material adheres to only one side of the rock. In this case, the side with organic material is the compression, known as the "part", while the corresponding impression is known as the "counterpart".

Paleontology is the study of the history of life on Earth as based on fossils. Fossils are the remains of plants, animals, fungi, bacteria, and single-celled living things that have been replaced by rock material or impressions of organisms preserved in rock.

5. The preserved evidence of the activity of an organism, such as its tracks, is called a(n) trace fossil.

If an organism becomes trapped in sediment, decomposition takes place at an extremely slow rate as the sediment dries out and becomes rock. When the rock is cracked open millions of years later, the impression of the organism can be seen outlined in the rock, as in the shell featured below. Mold fossil of a bivalve rock. This type of fossil shows an impression of the organism in rock. The actual plant or animal is the fossil in this type of fossil. Examples include: Footprints and burrows.

Casts & Molds: caused by deposits of sediment in cavities of organism, resulting in a three dimensional model. This fossil is formed when an organism steps in sediment or mud, the print is buried in sediment and then turns into sedimentary rock. How is a CARBON FILM formed? This type of fossil is formed when black material (element found in all life forms) settles out of organism, organism decays and evaporates.
