Natural Trap, Tibiae, Data

vendredi 18 octobre 2013 par Véra Eisenmann

In Table 1 are the original data (2 sheets) provided by John Howe. Some measurements seemed aberrant ; the are printed in red and highlighted in yellow ; the same specimen was measured twice and only the mean (X) was used. In Table 2 the corrected data I used are printed and highlighted in blue ; later on I discarded the diaphysis diameter because of its too large variation.

Scatter diagrams (Fig.1-3) show one distal end exceedingly large (36640), one specimen exceedingly robust (52070), and three very large specimens (33253, 47808, and 54449) ; a large variation exists even among the other tibiae. Most Natural Trap tibiae are bigger than in extant E. hemionus onager.
