The following figure was marked with incorrect boundary of Haversian

To make up for my mistake, I carefully studied again 20 micrographs of
the same area and marked on the following micrographs 15 red blood
cells, 5 cross sections of blood vessels and 3 Haversian canals—all
fossilized. This time no mistake, although these organisms of
meteorite have been much more heavily distorted than Earth/Mars
fossils.
