Dinosaur Fossil Petrification txheej txheem

Qhov nyuaj ntawm cov pob txha dinosaur thiab cov hniav yog ua los ntawm cov zaub mov. Minerals zoo li tawg thiab recrystallize hauv av, ua nyuaj, txheej txheem hu ua "petrification." Raws li cov sediment saum toj no txuas ntxiv thicken, cov seem tau faus tob thiab tob, thaum kawg tig mus rau hauv pob txha. Thiab cov sediments ib puag ncig tau hloov mus ua pob zeb tawv. Cov txheej txheem no qeeb heev.
Muaj ntau yam txaus ntshai nyob rau hauv tus txheej txheem ntawm fossilization rov qab mus rau saum npoo. Thaum lub sij hawm fossilization txheej txheem ntau txhiab xyoo, lub pob zeb nyob ib puag ncig tej zaum yuav tau buckled thiab deformed kom cov pob txha raug crushed. Tsis tas li ntawd, qhov kub siab nyob rau hauv qab ntawm lub ntiaj teb crust kuj yuav yaj cov pob txha. Tom qab khiav tawm cov kev puas tsuaj no, ib tus neeg tseem yuav tsum nrhiav cov pob txha ua ntej nws sib cais los ntawm cov pob zeb nyob ib puag ncig, txwv tsis pub cov pob txha yuav tawg thiab ploj mus.
