Zovala zochokera zaka zikwi makumi ambiri zapitazo zikugwiritsidwabe ntchito lerolino. Zovala zimenezo anangozikuta pathupipo. Koma, "Tarkhan Dress," yomwe idatchulidwa ku tawuni ya Egypt komwe idapezeka mu 1913, ili ndi zosokedwa bwino. Zinalembedwa ndendende pogwiritsa ntchito zida zaposachedwa kwambiri za radiocarbon zaka zisanu zapitazo. Zovala zakale kwambiri padziko lonse lapansi ndi chovala chansalu chatsatanetsatane chomwe, malinga ndi kafukufuku, chinali pakati pa 3482 ndi 3103 BC.
Malinga ndi Alice Stevenson, woyang’anira wa London’s Petrie Museum of Egypt Archaeology, nsalu zopezedwa pamalo ofukula zinthu zakale nthawi zambiri sizikhala zaka 2,000. Koma, diresi la Tarkhan ndilakale kuposa zaka 5,000 ndipo mwina linali lalitali pomwe linali latsopano, malinga ndi akatswiri.
Nthawi ina inali gawo la "mulu waukulu wansalu zonyansa" zofukulidwa ndi Sir Flinders Petrie mu 1913 pamalo omwe adatcha Tarkhan pambuyo pa mudzi wapafupi wa 30 miles kumwera kwa Cairo, archaeology.org adatero.
Mu 1977, ofufuza ochokera ku Victoria ndi Albert Museum akukonzekera kuyeretsa mulu waukulu wansalu zonyansa pamene adapeza chovala cha Tarkhan, chopangidwa bwino.
Ngakhale kuti m'zigongono ndi m'khwapa munali ziboda zosonyeza kuti wina anavalapo diresiyo, malaya ansalu a V-khosi ndi manja otambalala anali abwino kwambiri ngakhale anali ndi zaka zambiri.
Ofufuzawo adasunga nsaluyo, ndikuisoka pa silika ya Crepeline kuti ikhazikike ndikuyiwonetsa. Posakhalitsa, anali kutamandidwa monga chovala chakale kwambiri ku Igupto ndi chovala chakale kwambiri padziko lonse makamaka chifukwa cha ukalamba wa manda amene anapezekamo. Komabe, chifukwa chakuti manda amene chovalacho chinapezedwa anali atabedwa, ofufuza sakanatha kutchula zaka zenizeni za chovalacho.
Pamene nsalu ya chovalacho idawunikidwa m'zaka za m'ma 1980 pogwiritsa ntchito njira yamakono yotchedwa accelerator mass spectrometry, ankaganiziridwa kuti ndi yakumapeto kwa zaka chikwi chachitatu BC. Koma akatswiri amanena kuti deti limeneli n’lofala kwambiri.
Pamapeto pake, mu 2015, gulu la radiocarbon la University of Oxford lidasanthula zitsanzo kuchokera pazovala zomwe zimangolemera 2.24mg. Zovala za Tarkhan zimakhulupirira kuti zidakhalapo cha m'ma 3482 ndi 3102 BC, mwina kale kwambiri kuposa Mzera Woyamba wa Egypt (c. 3111-2906 BC).
