Peb feem ntau nrhiav cov pob txha hauv thaj chaw suab puam, qhov twg muaj pob zeb sedimentary es tsis yog pob zeb metamorphic lossis igneous pob zeb. Txoj cai tseem ceeb rau kev txiav txim siab qhov twg los tshawb nrhiav yog hnub nyoog geology: yog tias koj paub lub hnub nyoog ntawm cov pob zeb hauv ib cheeb tsam, koj tuaj yeem pib tshawb nrhiav tsiaj uas nyob rau lub sijhawm ntawd.
Cov kws tshawb fawb paleontologists feem ntau yuav pom cov pob txha nyob qhov twg?
Fossils feem ntau pom nyob qhov twg cov pob zeb sedimentary ntawm lub hnub nyoog raug - uas rau dinosaurs yog Mesozoic - raug nthuav tawm. Qhov chaw zoo tshaj yog kwj hav dej, pob tsuas thiab hillsides, thiab tib neeg tsim tawm xws li quarries thiab kev txiav.
paleontologists kawm fossils nyob qhov twg?
Kev ua haujlwm
Feem ntau cov kws tshawb fawb paleontologists siv sijhawm ntau hauv thaj teb los sau cov pob txha uas lawv kawm. Kev ua haujlwm hauv teb tuaj yeem ua tau nyob txhua qhov chaw ntawm thaj chaw roob toj siab mus rau lub chaw txua txiag zeb hauv zosNtawm txhua qhov chaw, cov pob zeb ua tiav tau tshawb fawb kom qhov chaw ntawm txhua pob pob txha (cov hnab dawb) tuaj yeem txiav txim siab.
Pleoanthropologists yuav mus nrhiav cov pob txha nyob qhov twg?
Fossils muaj nyob hauv pob zeb sedimentary. Rau cov pob txha los ua pob txha, lawv yuav tsum tau khaws cia los ntawm kev faus thiab tsis muaj kev cuam tshuam rau lub sijhawm ntev hauv cov av. Yog li, peb yuav tsum nrhiav thaj chaw uas faus pob txha ceev thiab tob hauv av. Qhov no suav nrog cov chaw nyob ze cov dej ntws los yog pas dej.
paleontologists kawm lawv qhov kev tshawb pom qhov twg?
