Los grados tafonomicos se definen utilizando cuatro caracteristicas tafonomicas de los organismos, que son: grado de fractura, articulacion (este criterio no aplica en gasteropodos), corrasion y orientacion; y tres caracteristicas sedimentologicas que incluyen el porcentaje de matriz, clasificacion y gradacion de la roca.

La corrasion es el grado de degradacion general de la superficie de un resto cuando no se pueden separar los posibles causantes de disolucion, bioerosion (corrosion) y abrasion, el indice de corrasion es una combinacion de abrasion mecanica, corrosion quimica y biologica (Brett & Baird 1986).

El grado tafonomico "A" caracteriza a este estrato debido a la escasa corrasion y la orientacion aleatoria (alineacion paralela de menos del 10%) de los ejemplares, asi como a la ausencia de gradacion del sedimento.

Aeolian erosion involves five different processes: reptation (creep) over eroded surfaces by the largest particles (diameter greater than 0.5 mm); saltation of the smallest particles (diameter 0.25-0.5 mm); deflation of the fine grains (diameter 0.1-0.25 mm); suspension of the fine particles (diameters below 0.1 mm); and corrasion, when obstacles are blasted by the impact of wind-borne particles (mainly due to saltation and deflation).
