 Sole markings are found most commonly in turbidite deposits, but are also often seen in modern river beds and tidal channels.Sole markings were first recognized in the Devonian rocks of New York State by James Hall in 1843.Originally, the features found on the undersides of beds were called "hieroglyphs", "fucoids", and "bio hieroglyphs", because of their structure and how they were thought to be created; however, the term "sole mark" is used by geologists at present.
