The main advantages of the acid-hot water method are: 1) A significant reduction of time compared to the Glauber's Salt method; 2) Large-sized samples can be treated, which makes it easier to extract fossils from bulk samples; 3) Fossils are cleaned of adhering sediment particles, which makes the method more reliable within a quantitative analysis of the sediments; 4) The method is particularly useful in examining drill cores, which have obvious sample size limitations; 5) The method has numerous applications in both the field and the laboratory in combination with waterblasting cleaning.
