The sandstone/siltstone-claystone heteroliths that underlie and overlie such thick claystone beds are often characterized by sparse to abundant trace fossil associations, dominantly Planolites isp., Thalassinoides isp., and Paleophycus isp., along with abundant plant fossils.
The large burrows that form the mottles are assigned to the ichnogenus Thalassinoides; these were probably produced by arthropods (Kendall, 1977; Coniglio, 1999).
