FIGURE 4. The loss of types over 260 years of reptile taxonomy. (A) Most of the 653 lost or not located types belong to species described in the late 1700s and early 1800s. While many Linnaean types still exist, roughly half of all original types from the 1700s are now lost. (B) While the number of described species and subspecies steadily increased, the loss of types decreased (A). See Supplementary Table S3 for individual types.
