Accurate calculation of the content volume, density and original weight of museum curated eggs.

ABSTRACT: Worldwide museums hold collections of eggshells representing material for descriptive studies. However, an obstacle to this is the lack of information about the original contents and weight of the entire egg (W). This study aimed to fill this gap though development of a methodological mechanism for calculating the volume of the egg interior (V_i), its density (D_i) and W. To determine V_i, it is sufficient to measure four geometric dimensions of the egg and shell thickness. The D_i value depends on the surface area-to-volume ratio (S/V) and can be calculated from an empirical relationship. For its derivation, data on 454 eggs from 447 avian species, 95 families and 13 orders were used. Imputing data on the contents and shell weight (W_s), w
