Yog li feem ntau cov pob txha muaj nyob hauv pob zeb sedimentary, qhov twg maj mam siab thiab qis qis tso cai rau kev khaws cia ntawm lub neej yav dhau los. Fossils dhau los ua ib feem ntawm cov pob zeb sedimentary thaum sediments xws li av nkos, xuab zeb, plhaub thiab pebbles npog cov nroj tsuag thiab tsiaj cov kab mob thiab khaws lawv cov yam ntxwv los ntawm lub sijhawm.
Yuav ua li cas cov kab mob no feem ntau yuav khaws cia ua pob txha?
Lub plhaub tawv ntawm clam muaj feem ntau yuav fossilize vim nws tiv taus ntau dua rau kev lom neeg thiab kev puas tsuaj ib puag ncig. Vim li no, cov hniav, pob txha thiab lwm qhov nyuaj ntawm cov kab mob muaj ntau ntau hauv cov ntaub ntawv fossil tshaj li cov ntaub so ntswg. 4. Vim li cas qhov kev faus neeg sai sai pab tau rau hauv cov txheej txheem fossilization?
Qhov chaw twg yog qhov zoo tshaj plaws ntawm cov pob txha?
Yuav luag tag nrho cov pob txha yog khaws cia hauv cov pob zeb sedimentary. Cov kab mob uas nyob hauv qhov chaw qis (xws li pas dej lossis dej hiav txwv bass) muaj qhov zoo tshaj plaws ntawm kev khaws cia. Qhov no yog vim lawv twb nyob rau qhov chaw uas cov av yuav faus rau hauv lawv thiab tso lawv tawm ntawm cov khawb thiab lwj.
Qhov twg ntawm ib puag ncig hauv qab no yuav khaws cov pob txha?
Fossils muaj feem ntau yuav khaws cia hauv marine ib puag ncigpiv txwv, qhov twg sai sai faus los ntawm sediments. Tsis tshua muaj kev thaj yeeb nyab xeeb muaj xws li cov pob zeb roob uas cov pob txha lwj sai sai lossis ob peb cov sediments tau muab tso rau faus lawv.
Cov xwm txheej twg zoo rau kev khaws pob txha?
Ob yam uas haum rau kev khaws cia ntawm lub cev raws li pob txha yog RAPID BURIAL thiab HARD PARTS.
