Description	Method for extraction of calcified or pyritised fossils from calcareous rocks has been developed. It is based on the differential speeds for dissolution of macrocrystalline and microcrystalline calcite in 38% sulphuric acid. Method consists of the following steps: preparation of specimen for extraction (involving drying the fossil and surrounding rock), submerging the dry specimen in a bath of 38% sulphuric acid (covered by a lid), leaving the specimen in the bath for a period of 1 minute to 2 hours, removal of the specimen from the bath and washing it under a stream of tepid water, submerging the specimen in a neutralising bath for a period of 2-6 hours, removal and cleaning of the specimen, drying of the specimen. Disregarding the scientific value of these macrofossils (important for palaeontology, palaeoecology, biostratigraphy, palaeobiogeography and sedimentology) also commercial-industrial uses have been described.
