Stratigraphy
Formation:Jaffna Limestone
Stratigraphic resolution:bed
Stratigraphy comments: STRATIGRAPHIC RELATIONS: From Jaffna Limestone, which unconformably overlies Precambrian basement, and is unconformably overlain by recent sand dunes and coral reefs, and Quaternary red earth. AGE: late Early Miocene (Burdigalian) on the basis of foraminifera. STRATIGRAPHIC POSITION: From unknown position within formation.
Lithology and environment
Primary lithology:shelly/skeletal,white,yellow lithified "limestone"
Includes fossils?Y
Lithology description: SPECIFIC LITHOLOGY: Hard, partly crystalline, compact, indistinctly bedded creamy coloured rock. Massive in parts but some layers are richly fossiliferous. LITHIFICATION: Lithified, based on facies description.
Environment:shallow subtidal indet.
Geology comments: ENVIRONMENT: Shallow marine, carbonate facies, probably adjacent to coral reef environments.

Collection method comments: COLLECTOR: Unknown collector. REPOSITORY: Unknown repository, possibly Geological Survey Department, Sri Lanka or the National Museum of Sri Lanka.
Taxonomic list comments:COVERAGE: Exhaustive for gastropoda, bivalvia, foraminifera, and anthozoa. NOMENCLATURE: Not an authoritative publication, but with relatively modern nomenclature, and subgenus and species-resolution assignments.
