And now something else I just looked carefully through the two pages of Summers Smith with most stuff about this species to see if I missed anything and I did Summers Smith mentions that Tchernov attributed predomesticus to the Yabrudian layers of Oumm Qatafa in a contribution to a 1984 volume of Animals and Archaeology I don t know what Summers Smith means by this if Tchernov found more fossils or dated them better or something else
