FIGURE 1. Image of a Long-Eared Owl TMT, showing the measurement landmarks. Abbreviations: ML, maximum shaft length between the longest proximal-distal ends of the TMT; MW, midshaft transverse width of the TMT; TMT, tarsometatarsus.
FIGURE 2. Plot of the lengths of La Brea Athene cunicularia TMTs through time. Open diamonds: individual specimens; solid squares: mean for each pit.
FIGURE 3. Plot of the lengths of La Brea Asio otus TMTs through time. Open diamonds: individual specimens; solid squares: mean for each pit.
FIGURE 4. Plot of the robustness (midshaft cross-sectional area divided by length) of Athene cunicularia TMTs through time. Open diamonds: individual specimens; solid squares: mean for each pit.
FIGURE 5. Plot of the robustness (midshaft cross-sectional area divided by length) of Asio otus TMTs through time. Open diamonds: individual specimens; solid squares: mean for each pit.
FIGURE 6. Time-series analysis of length (mm), width (mm), depth (mm), and robustness of tarsometarsi of Asio otus through the last 29 ka at RLB. As is apparent from the statistical analysis (Table 6), they exhibit either a unidirectional random walk or complete stasis.
