'Hortolà P, 2001: Morphological Characterisation of Red Blood Cells in Human Bloodstains on Stone: A Systematical SEM Study. Anthropologie (Brno) 39, 2-3: 227-232'.
Mammalian erythrocytes or red blood cells (RBC) have been previously reported as forming part of residues on prehistoric implements. On the basis of the Principle of Actualism, several thick smears of human blood were obtained on chert. After increasing lengths of storage time span (1-36 months), the bloodstains were micromorphologically studied via scanning electron microscopy. Results revealed, in all the smears, the presence of an erythrocyte acme-zone with packed RBC, as well as negative replicas and moon-like shapes. Morphologies were found to be time-independent, and furthermore those erythrocyte acme-zones with packed RBC to be thick-bloodstain characteristic.
