Ages and eye lens masses of the 111 known-age hog deer used in our analyses.

The data file is composed of two named columns. 'Age' is the age (days) of the hog deer since birth. 'Mass' is the eye lens dry mass (g) for either (i) the heaviest of the two eye lenses (if two eye lenses were collected) or (ii) the one eye lens if only one eye lens was collected. There are data for 111 hog deer (i.e. one individual per row). Ages range from 130 to 5393 days and eye lens dry masses range from 0.2092 to 0.5485 g.
