| Stratigraphy comments: said to be late Tiffanian said by Gingerich and Childress 1983 to be SC-228, and by Butler et al. 1981 to be SC-239; these two localities are stratigraphically very close according to the latter, but SC-239 is near the top of C26n and SC-228 near the bottom of C25r according to Secord et al. 2006 meter level given by Gingerich and Childress 1983; accords with figured section of Butler et al. 1981 | |||||
