Stratigraphy
Formation: | Lower Headon Beds | ||||
Stratigraphic resolution: | bed | ||||
Stratigraphy comments: This author considers the Lower Headon Beds to be a formation, HH2 refers to a locality in the second lowest mammal-bearing unit (thickness approximately 15 cm), which passes upwards into a lignitic clay (thickness approx. 5 cm). This is the upper portion of the Lower Headon Beds (approx. 18 m above HH1) |
Lithology and environment
Primary lithology: | silty,sandy,calcareous claystone |
Secondary lithology: | shelly/skeletal,green calcareous,carbonaceous claystone |
Includes fossils? | Y |
Lithology description: overall lithology is claystone with interbedded marl (some silty/sandy) and limestone, fossils come from a green clay with bivalves which passes upwards into a lignitic clay. These strata are overlain by a pale brown marly limestone. | |
Environment: | marine indet. |
Taphonomy
Modes of preservation: | body |
Size of fossils: | macrofossils,mesofossils |
Disassociated major elements: | some |
Disassociated minor elements: | many |
Collection methods and comments
Collection excludes: | some macrofossils |
Collection methods: | bulk,sieve,field collection |
Minimum sieve size: | 0.500 |
Rock censused: | 1600 kg |
Reason for describing collection: | taxonomic analysis |
Collection method comments: This is probably the same location used by Prestwich, 1946, but his stratigraphy is all screwed up, it is my guess that HH2 is the same as his bed 45 |
