Possum crushing and incisor marks on chewcard.
The incisor teeth impressions are made by the two front incisor teeth (lower or upper jaw). Each pair of marks (one for each tooth) are characteristically separated by a medial notch of up to 1 mm (the gap between the two teeth). Complete incisor pairs are 4.5 - 7 mm wide.
