Possum incisor teeth marks on bark.
The two parallel marks have been made by the top centre incisor teeth. The width, at more than 4.5 - 5 mm, indicates possum, as does the thin slightly raised dark line down the middle. The line reflects the gap between the teeth where the bark was not scraped away. The paler marks appear relatively fresh, on top of older damage that had already stripped much of the bark (at right) away. This was a fivefinger tree (Pseudopanax arboreus) on the Coromandel Peninsula.
