Archaeologists tau tshawb pom ib tug zoo-preserved 1,000-xyoo-laus ntaiv ntoo nyob rau hauv lub tebchaws United Kingdom. Excavations ntawm Field 44, ze Tempsford hauv Central Bedfordshire, tau rov pib dua, thiab cov kws tshaj lij tau pom ntau qhov kev tshawb nrhiav keeb kwm yav dhau los.
Raws li pab pawg MOLA archaeology, ob peb ntawm cov khoom uas tau rov qab los ntawm Iron Age yog qhov tsis tshua muaj tshwm sim. Tib neeg tau siv ntau yam ntoo yav dhau los, tshwj xeeb hauv cov tsev xws li cov tsev nyob ib puag ncig, uas yog cov qauv tseem ceeb ntawm cov neeg nyob thoob plaws lub Hnub Nyoog Hlau (800BC - 43AD).
Feem ntau, tsuas yog cov pov thawj peb pom ntawm cov tsev nyob ib puag ncig yog cov ncej qhov, qhov twg cov ncej ntoo twb rotted lawm. Qhov no yog vim ntoo tawg sai heev thaum faus rau hauv av. Qhov tseeb, tsawg dua 5% ntawm qhov chaw archaeological thoob plaws tebchaws Askiv muaj cov ntoo seem!
Yog tias ntoo decomposes sai heev, cov archaeologists nrhiav tau li cas?
Ntoo yog tawg los ntawm cov kab mob thiab cov kab mob xws li kab mob. Tab sis, yog tias ntoo nyob rau hauv av ntub heev, nws tuaj yeem nkag mus rau hauv dej thiab ua dej. Thaum ntoo puv dej thiab faus rau hauv av ntub, nws tsis qhuav tawm.
Qhov no txhais tau tias oxygen tsis tuaj yeem nkag mus rau ntoo. Cov kab mob tsis tuaj yeem muaj sia nyob tsis muaj oxygen, yog li tsis muaj dab tsi los pab ntoo decompose.
“Ib feem ntawm peb qhov chaw khawb av yog lub hav ntiav uas cov dej hauv av tseem sib sau ua ke. Yeej, qhov no txhais tau tias hauv av ib txwm ntub thiab boggy.
Nws yuav zoo ib yam thaum lub Hnub Nyoog Hlau thaum cov neeg zej zog siv thaj chaw no los sau cov dej los ntawm qhov dej ntiav. Txawm hais tias qhov no txhais tau tias kev khawb av yog av nkos heev rau cov kws tshawb fawb keeb kwm yav dhau los, nws kuj tau ua rau qee qhov kev tshawb pom zoo, "MOLA tau hais hauv tsab ntawv tshaj tawm.
Ntau yam khoom ntoo zoo kawg tau khaws cia rau hauv av boggy rau 2000 xyoo. Ib tug ntawm lawv yog Iron Age ntaiv siv los ntawm cov zej zog hauv zos kom ncav cuag dej los ntawm qhov dej ntiav.
Cov kws tshawb fawb kuj tau tshawb pom ib yam khoom uas zoo li lub pob tawb tab sis tsis yog. Nws yog tiag tiag wattle panels (woven twigs thiab ceg) npog nrog daub, ua los ntawm cov ntaub ntawv xws li av nkos, crushed pob zeb, thiab straw los yog tsiaj plaub hau. Lub vaj huam sib luag no tau siv los ua kab dej, tab sis wattle thiab daub kuj tau siv los ua tsev rau ntau txhiab xyoo. Pom qee qhov khaws cia los ntawm ntev dhau los raws li Lub Hnub Nyoog Hlau yog qhov tsawg kawg nkaus.
Tom qab nrhiav pom cov ntoo khaws cia, archaeologists yuav tsum ua sai sai. Qhov tseem ceeb tshaj plaws yog cov ntoo khaws cia kom ntub kom txog thaum nws tuaj yeem ua tib zoo ziab tawm hauv chav kuaj los ntawm cov kws tshaj lij kev saib xyuas. Yog tias nws tsis ntub, nws yuav pib decompose sai thiab tuaj yeem tawg tag!
Peb kawm tau dab tsi los ntawm ntoo?
“Peb tuaj yeem kawm ntau yam ntawm cov khoom ntoo no. Raws li qhov pom tau tias tib neeg tsim thiab siv lawv li cas hauv lawv lub neej niaj hnub, nrhiav seb hom ntoo twg lawv siv yuav qhia peb txog cov ntoo uas loj hlob hauv cheeb tsam. Qhov no tuaj yeem pab peb rov tsim kho cov toj roob hauv pes zoo li cas rau lub sijhawm, thiab thaj chaw ntawd hloov pauv li cas hauv keeb kwm.
Nws tsis yog ntoo xwb uas tuaj yeem khaws cia hauv qhov chaw ntub dej! Peb kuj nrhiav tau kab, noob, thiab paj ntoos. Tag nrho cov no pab peb ib puag ncig archaeologists tsim ib daim duab ntawm yuav ua li cas toj roob hauv pes ntawm Bedfordshire thiab Cambridgeshire saib 2000 xyoo dhau los.
Saib cov paj ntoos thiab cov nroj tsuag khaws cia hauv dej, lawv twb tau txheeb xyuas qee cov nroj tsuag uas tau loj hlob nyob ze, suav nrog buttercups thiab rushes! " pab neeg tshawb fawb MOLA piav qhia.
Archaeological ua hauj lwm ntawm qhov chaw txuas ntxiv mus. Tam sim no cov ntoo yuav ua tib zoo ziab los ntawm peb cov neeg saib xyuas, thiab tom qab ntawd cov kws tshaj lij tuaj yeem kuaj xyuas cov khoom ntoo no.
