Microfossils of bacteria and fungi are probably among the most abundant, but they are also the smallest, so they are more difficult to find and study. Rads have always been marine and all, as far as we know, are planktonic. Finally, microfossils are used extensively in science education. While the small size is the main criterion for classifying microfossils, it is important to note that some remains of foraminifers may be more than 2 mm or about 15 cm in diameter, but they are still referred to be microfossils. The newly reported microfossils here occur below strata containing possible first occurrence of cloudinids (following an unillustrated report of. 1979). Microfossils useful in hydrocarbon exploration can be divided into five principal microfossil groups based on the composition of the shell (test) or hard parts.
