"[echinoderms mostly isolated plates]...little evidence of regular current action, although some winnowed debris piles are found...thin sections show mottled and swirled texture typical of burrowed and biogenically reworked sediments..Frest and Strimple ('77b) comment on prevalence of [crinoids] with planar arm fans...as representing quiet offshore (below normal wave base) environment with relatively slow rate of sediment accumulation. A BA3-4 boundary position seems likely from the echinoderms"\r\n\r\nSEP environmental call based on given information and knowledge of regional geology
