A microfossil is a fossil that is generally between 0.001 mm and 1 mm in size, [2] the visual study of which requires the use of light or electron microscopy. A fossil which can be studied with the naked eye or low-powered magnification, such as a hand lens, is referred to as a macrofossil .

ProbID is a software tool designed to identify peptides from tandem mass spectra using a protein sequence database. It was developed at the Bioinformatics Group, Institute of Computing Technology, Chinese Academy of Sciences, Beijing, China. [16] ProLuCID Freeware
Fusulinid from the Plattsmouth Chert, Red Oak, Iowa ().Micropaleontology can be roughly divided into four areas of study on the basis of microfossil composition: (a) calcareous, as in coccoliths and foraminifera, (b) phosphatic, as in the study of some vertebrates, (c) siliceous, as in diatoms and radiolaria, or (d) organic, as in the pollen and spores studied in palynology.
SIRIUS is a Java-based open-source software for the identification of small molecules from fragmentation mass spectrometry data without the use of spectral libraries. It combines the analysis of isotope patterns in MS1 spectra with the analysis of fragmentation patterns in MS2 spectra.
However, for microfossils that has simple morphology, compositional analysis by FTIR is an alternative way to better identify the biological affinities of these species. [ 4 ] [ 5 ] The highly sensitive FTIR spectrometer can be used to study microfossils which only have small amount of specimens available in nature.
Microfossils found in chert extend the Barberton microfossil record back to 3.5 billion years. All three types of microfossil morphologies are found in cherts. Chert can have a variety of colours, but microfossils are typically found in black cherts, as the dark color can indicate organic material. [1]
In addition to observations being identified by others in the community, iNaturalist includes an automated species identification tool, first released in 2017. [29] Images can be identified via a computer vision model which has been trained on the large database of the observations on iNaturalist. [ 22 ]
