Why this word is great
MORTICHNIUM — [Noun] A fossilized trail or track preserving the final movements of an animal in the moments before its death. From the Latin mors, mortis ("death") and the Greek -ichnion ("trace, track"), with the Latin-derived suffix -ium. Unlike an "ichnofossil," which neutrally records any past activity—a casual burrow or grazing scar—or a static "death assemblage," which documents a mere congregation of remains, a mortichnium is a singular narrative, a verb turned to stone. It is the desperate, asymmetrical skid of a wounded amphibian through Permian mud; the final, perfect spiral of a trilobite that could go no further; the frantic, scrawled signature of a horseshoe crab caught in an anoxic lagoon. It fossilizes not a corpse, but the act of becoming one: a map with only one destination.
