Preservational models explaining the heterogeneities between (A) Montceau-les-Mines, (B) Mazon Creek, and (C) Herefordshire Lagerstätten. Cellular sheets in direct contact with the surrounding environment “D”; and internal organs “E”; “P” is for probability. P(E|D) is the probability of finding internal organs (E) considering that external epidermis (D) has been identified
