Semantic segmentation of vertebrate microfossils from computed tomography data using a deep learning approach [PDF]
Journal of Micropalaeontology, 2021 Vertebrate microfossils have broad applications in evolutionary biology and stratigraphy research areas such as the evolution of hard tissues and stratigraphic correlation. Classification is one of the basic tasks of vertebrate microfossil studies.

Microfossils in the Ordovician erratic boulders from Southwestern Finland [PDF]
Bulletin of the Geological Society of Finland, 1995 Chitinozoans, ostracods and acritarchs found in four glacially transported limestone boulders from the south-western coast of Finland have been studied in order to test the usefulness of these microfossil groups in age determinations. Also rare specimens
