Formation:	Castilletes	Member:	lower Castilletes
Regional section:	Cocinetas	Regional bed:	49 m
Regional order:	bottom to top
Stratigraphic resolution:	bed
Stratigraphy comments: STRATIGRAPHIC RELATIONS: From the Castilletes Formation, which conformably overlies the Jimol Formation (early Miocene) and is unconformably overlain by the Ware Formation. AGE: Burdigalian-Langhian, on the basis of macrofaunal composition and stratigraphic position; direct age established by extrapolation of Sr-isotope dating by enterer. STRATIGRAPHIC POSITION: Likely in lower part of the Castilletes Fm, but in a faulted part of the sequence; from 49 m above Jimol/Castilletes contact.

Primary lithology:	gypsiferous,shelly/skeletal poorly lithified siltstone
Includes fossils?	Y
Lithology description: SPECIFIC LITHOLOGY: Poorly consolidated shell bed, silty matrix, gypsiferous. LITHIFICATION: Poorly lithified, as determined in the field and based on museum-reposited specimens.
Environment:	lagoonal
Geology comments: ENVIRONMENT: Shallow marine (0-5 m), siliciclastic, probably reduced salinity.

Modes of preservation:	body,original aragonite,original calcite
Degree of concentration:	concentrated
Size of fossils:	macrofossils,mesofossils
Spatial orientation:	random
Preservation of anatomical detail:	medium
Abundance in sediment:	abundant
Size sorting:	poor
Fragmentation:	occasional
Bioerosion:	none
Encrustation:	none
Temporal resolution:	time-averaged
Spatial resolution:	parautochthonous

Collection excludes:	some macrofossils
Collection methods:	bulk,field collection
