Basis of coordinate:based on nearby landmark
Geographic resolution:local area
Time
Period:Paleogene Epoch:Eocene
Stage:Priabonian 10 m.y. bin:Cenozoic 3
Key time interval:Late/Upper Eocene
Age range of interval:37.71000 - 33.90000 m.y. ago
Stratigraphy
Formation:Headon Beds Local bed:Rodent
Stratigraphic resolution:bed
Stratigraphy comments: this bed is synonymous with the "Limnaea Marl" and is in the upper portion of the Lower Headon Beds, (less than 1 m from the top) at this locality. In her publications, M. of Hastings separated this into two units (her Stratum 1 and 2).
Lithology and environment
Primary lithology:shelly/skeletal argillaceous marl
Secondary lithology:concretionary,ferruginous sandy,calcareous claystone
Includes fossils?Y
Includes fossils?Y
Lithology description: marl with overlying dark clay, the rest of the Headon Beds are predominantly clays, with varying amounts of sand, limestone and ironstone
Environment:marine indet.
Taphonomy
Modes of preservation:body
Size of fossils:macrofossils,mesofossils
Articulated whole bodies:some
Associated major elements:some
Disassociated major elements:some
Disassociated minor elements:some
Collection methods and comments
Collection excludes:some macrofossils
Collection methods:field collection
Reason for describing collection:taxonomic analysis
Collection method comments: In 1852, the Marchioness of Hastings published an almost identical paper to her 1853 report. I used the later English version, but the earlier paper is the more primary reference.
