A fossil is any evidence of past life. Fossils formed from animal bodies or their imprints are called body fossils. When people think about fossils, they usually think about body fossils. Trace fossils are another kind of fossil. A trace fossil is any evidence of the life activity of an animal that lived in the past. Burrows, tracks, trails, feeding marks, and resting marks …

General Information. Freshwater snails come under the phylum mollusca and the class gastropoda. They can be found in almost any freshwater habitat, including ponds, streams, lakes, and rivers (Hamrsky). Many freshwater snails are amphibious, so they can also be found in moist soil, or among plants found near bodies of water.Excrements in amber can be good trace fossils for determining the existence of snails, even if the direct morphological traits of snails such as the shell are not preserved.If you can split the rock, check the shale layers and the limestone for snails, trilobites, crinoids, clams, and rarer animals that were swept up in mudslides.
