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; (…)
In Table 1 are the original data (6 sheets) provided by John Howe. Most measurements were not taken in my way and moreover not in the same way by the people who took them (compare the values on the lateral condyle height on sheet I, II, III and IV, V, VI-1 to 14)). The same specimen (42639) is (…)
In Table 1 are the original data (2 sheets) provided by John Howe but measured by a student who apparently made some mistakes. Some data appeared redundant, either because they originated from the right and left side of the same animal or because the same specimen was measured twice. In Table 2 (…)
John Howe sent me copies of his data on seven sheets. Some data were redundant. In Table 1 you may find the original data and in Table 2 - the ones I have used.
A few phalanges were obviously different from the rest by their size. They will be discussed later, after the bulk of the material (…)
Like for the first phalanges, I received from John Howe copies of his data on second phalanges (Ph2) on separated (10) sheets. A few data were redundant, in that cases I used their mean noted ’-X’. In Table 1, you may find the original data, in Table 2 - the ones I used, and in Table 3 - the (…)
Like the rest of the material of Natural Trap, the first phalanges (Ph1) were measured by John Howe and his student(s). John Howe sent me copies of these data on nine sheets. Some data appeared redundant, either because they originated from the right and left side of the same animal or because (…)
Like the MC of Natural Trap, the third metatarsals (MT) were measured by John Howe (sheets I and II) and one student (sheets III and IV). The diagrams (Fig.1,2) show again that they did not measure the diaphysis depth (4) in the same way. There is no way to increase the measure 4 but there is a (…)
Like the rest of the material of Natural Trap, the third metacarpals (MC) were measured by John Howe (sheets I and II) and one student (sheets III and IV). Looking at the diagrams (Fig.1,2) it is obvious that they did not measure the diaphysis depth (4) in the same way. There is no way to (…)
In Table 1, are the original data provided by John Howe (2 sheets).
Scatter diagrams (Fig.1 and 2) show that Natural Trap humeri are longer than in extant E. hemionus onager (Fig.1) as well as wider and flatter (Fig.2).
As in other limb bones, a few specimens seem larger, possibly because (…)
