Stratigraphy
Formation:Henryhouse Member:Upper
Stratigraphic resolution:group of beds
Stratigraphy comments: Upper Henryhouse, assigned age range of Ludlow-Pridoli by authors. Collection comes from beds "approximately 3 m [in total thickness] beginning 5 m below Haragan contact"
Lithology and environment
Primary lithology:shelly/skeletal marl
Includes fossils?Y
Lithology description: "Moderately to abundantly fossiliferous...The lithology is a mud-supported marlstone, with skeletal debbris ranging from about 17-50%."
Environment:deep subtidal ramp Tectonic setting:cratonic basin
Geology comments: "Echinoderms most often cups and calices...but a very small proportion of complete crowns also occur..root systems and holdfasts moderately common...skeletal grains generally unabraded, and there is only occasional evidence of winnowing. Trilobites highly fragmented, as are many of the common bryzoan taxa. Brachiopods usually intact. The abundant and diverse inadunate and flexible crinoid fauna, limited but diverse non-crinoid echinderms, and rare but diverse camerates, sugges a rather deep water assemblage occasionally disturbed by storms, i.e. well below normal wave base. Base on [brachiopods] a position analogous to BA outer 4 or inner 5 is likely. The brach. faunaa differs somewhat from that described by Amsden 91951) from more typical Henryhouse sections...This argillaceous carbonate community somewaht resembles the Midcontinent carbonates from which the Pisocrinus-Gissocrinus assoc. [PBDB coll. 26815, 26816] is derived, but echinoderm diversity is much less and brachiopods are correspondingly more prominent in the younger community." [This marl facies is between shallower limestone facies and deeper graptolite shale facies according to some of Amsden's maps.]

Collection methods and comments
Reason for describing collection:paleoecologic analysis
Collection method comments: Table 45.49, which gives abundances for White Mound. I have added Nummicrinus, which is mentioned by name in text, but would appear to be included in the table only as part of the "lecanocrinid spp. (plates)."
