Stratigraphy
Geological group:Sherwood Sandstone Formation:Otter Sandstone
Stratigraphic resolution:formation
Stratigraphy comments: lower part of the formation, early-mid Anisian: "The unit is dated as Anisian on the basis of faunal comparisons and matching with palynologically dated units in the English Midlands... This has since been confirmed by magnetostratigraphy (Hounslow and McIntosh 2003), who found that the lower parts of the Otter Sandstone Formation correspond to the early and mid Anisian, and the upper parts, which contain the majority of the macrofossils correlate with late Anisian and latest Anisian magnetozones on the marine standard."
Lithology and environment
Primary lithology:"cross stratification",concretionary lithified conglomeratic sandstone
Includes fossils?Y
Lithology description: "At Otterton Point hard, calcite-cemented, cross-bedded sandstone units in the Otter Sandstone Formation contain clacite-cemented rhizoliths and other calcrete formations...the [specimen] came from the zone of breccia and calcite-cemented nodules"
Environment:dry floodplain
Geology comments: "Purvis and Wright (1991) attributed the large vertical rhizoliths to deep-rooted phreatophytic plants which colonized bars and abandoned channels on a large braidplain"
