FOSSILS SPECIMEN: AMPHIBIANS

Fossils are defined as any evidenceĀ of prehistoric life. There are two types of fossils: Body Fossils include remains of skeletal bones, shell, carapace, test and teeth. Trace Fossils are clues the organism existed such as foot prints, tracks, burrows and coprolites (fossil dung).

 

The term Amphibian comes from the Greek word “amphibios” meaning “to live a double life” in reference to the stages of their life cycle. Amphibians are more advance then lob finned fish by having lungs and legs. The first Amphibians appear during the Late Devonian some 370 million years ago and persist to this day. All amphibians lay eggs in water and the young undergo metamorphosis from larva with gills to air breathing adults, most of which have lungs. To see my amphibian models click here.
