Stadi di alterazione dell'osso (Behrensmeyer 1978) — an Extended Matrix vocabulary module.
A six-stage ordinal scale describing the progressive surface alteration of bone exposed on or near the ground surface. Definitions here are restatements, not transcriptions, of the stages published by A. K. Behrensmeyer in 1978.

Surface intact and greasy in appearance, with no cracking or flaking; soft tissue may still adhere.
Stadio di alterazione 0 — Superficie integra e di aspetto untuoso, senza fessurazioni ne' sfaldature; puo' esserci ancora tessuto molle aderente.

First cracking appears, running parallel to the fibre structure of the bone; articular surfaces may show a mosaic pattern of fine cracks.
Stadio di alterazione 1 — Compaiono le prime fessurazioni, parallele alla struttura fibrosa dell'osso; le superfici articolari possono mostrare un reticolo a mosaico di fessure sottili.

The outermost layers of compact bone begin to flake away, usually along existing cracks; flakes are thin and still partly attached, and cracking has deepened.
Stadio di alterazione 2 — Gli strati piu' esterni dell'osso compatto cominciano a sfaldarsi, di norma lungo le fessure gia' presenti; le scaglie sono sottili e ancora in parte aderenti, e le fessurazioni si sono approfondite.

https://w3id.org/extendedmatrix/vocab/taph-weathering/stage-3
Patches of rough, uniformly altered compact bone appear, with a fibrous texture; alteration penetrates roughly one to one and a half millimetres and the original surface is no longer preserved in those patches.
Stadio di alterazione 3 — Compaiono chiazze di osso compatto ruvido e alterato in modo uniforme, di tessitura fibrosa; l'alterazione penetra all'incirca uno-un millimetro e mezzo e in quelle chiazze la superficie originaria non e' piu' conservata.

The whole surface is coarsely fibrous and rough; splinters are loose and detach easily, and the alteration reaches the inner cavities of the bone.
Stadio di alterazione 4 — L'intera superficie e' grossolanamente fibrosa e ruvida; le schegge sono mobili e si staccano con facilita', e l'alterazione raggiunge le cavita' interne dell'osso.

https://w3id.org/extendedmatrix/vocab/taph-weathering/stage-5
The bone is disintegrating in place into large splinters; the original shape of the element may no longer be determinable.
Stadio di alterazione 5 — L'osso si sta disgregando in posto in schegge grandi; la forma originaria dell'elemento puo' non essere piu' determinabile.
