Size-frequency distributions of greenbone FL reconstructions from cranial bone dimensions, ordered by decreasing mean FL from top down. The curves for Mana Island 1 and Kokohuia are not shown, as only seven bones were able to be measured from these two sites. The heavy black dashed line is the minimum legal size for greenbone in New Zealand. The heavy red dashed line is the maximum fish size that could be missed using a 6.3 mm sieve (see text).
