Lithology description: "At the base of the section a band of chert nodules is indicated, measuring 2 feet, which is possibly the true junction of Gault and Greensand, although in the Memoir on the Geological Survey of the Isle of Wight 50 feet of micaceous sands below this point have been included in the Greensand... The next 20 feet of compact red sand are for the most part unfossiliferous; or rather the organic remains have been nearly obliterated. It is harder in texture than the succeeding 4 feet. Without any other lithological change than hardness, we suddenly come to a zone in which well-preserved casts of Mollusca abound, differing, as will be noted, from the Upper Cherts and Rags in a remarkable manner." (Parkinson 1881)

Taxonomic list comments:"It was from this section, exposed on the St. Lawrence beach, that Captain Saxby procured a species of Crayfish; and a second specimen has been found within the last eighteen months in the same locality... The Crayfish obtained by Saxby [is] figured in Prof. Bell's Monograph of the Crustacea" (Parkinson 1881)
"At the base of [the sandstone] (that is, 20 feet from the lowest chert nodules) an Ammonite occurs, which, so far as I can discover, has not been described." (Parkinson 1881)
