AMNH 10606 (Equus scotti skull photographs)

E. scotti, Introduction (Rock Creek, Texas E. scotti)

Thursday 26 March 2020 by Véra Eisenmann
E. scotti, Rock Creek, Texas, is probably the best represented Middle Pleistocene horse (skulls and skeletons). Unfortunately the type (Gidley 1901, Plate XX) is a mounted skeleton (AMNH 10606) which apparently no one could study in detail. The skull AMNH 10612 figured by Gidley (1900, fig.3) (...)

Natural Trap, Wyoming, Introduction (Natural Trap, Wyoming)

Saturday 19 October 2013
It was John Howe who studied the equids of Natural Trap but his manuscript was never published. Instead, part of his work was included in "Eisenmann V., Howe J., Pichardo M. 2008 (published in 2011): Old World Hemiones and New World slender species (Mammalia, Equidae). Palaeovertebrata (...)


Natural Trap, Tibiae, Data (Natural Trap, Appendix)

Friday 18 October 2013
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; (...)


Natural Trap, Tali, Data (Natural Trap, Appendix)

Friday 18 October 2013
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 (...)


Natural Trap, Crania and Mandibles, Data (Natural Trap, Appendix)

Natural Trap, Radii, Data (Natural Trap, Appendix)

Friday 18 October 2013
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 (...)


Natural Trap, Ph3, Data (Natural Trap, Appendix)

Friday 18 October 2013
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 (...)


Natural Trap, Ph2, Data (Natural Trap, Appendix)

Friday 18 October 2013
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 (...)
