Stratigraphy
Formation: | Laurel | ||||
Stratigraphic resolution: | formation | ||||
Stratigraphy comments: "Formational assignment of the strat with this community is somewhat problematic. At most outcrops, the Laurel-Waldron contact is abrupt and has low relief, even though in many places it is a hardground. At Sandusky and elsewhere it is more gradiational. The unit was termed the 'transitional beds' by Frest (1977) and assigned, somewhat arbitrarily, to the Laurel because of the mixed fauna and predominantly carbonate lithology." |

Lithology description: "Abundantly fossiliferous. The most common lithology is whole fossils or large-clast grainstone, but packstone textures are almost equally common. Individual beds generally do not exceed 3 cm...Many are strongly graded, with fines generally on the upper surfaces. Some debris layers have fines winnowed out although they are otherwise poorly sorted. Large-debris lenses are common, but these rarely persist laterally for more than 2 m...." | |||
Environment: | deep subtidal indet. | Tectonic setting: | cratonic basin |
Geology comments: "...most intact cups are those of resistant taxa...holdfasts and root systems common...This environment was evidently fairly frequently subject to wave winnowing, and hence likely occurred above mean storm wave base. Excellent and unbroken preservation of many echinoderm calices and brachiopods preculdes the presence of regular currents. The moderate diversity of both echinoderms and brachiopods is suggestive of BA 3. A. Boucot...states that the brachiopod assemblage most strongly suggests outer BA 3; this is consistent with the sizable blastozoan representation as well."
