Yog li cov kws tshawb fawb siv bulldozers mus khawb cov pob zeb thiab av. 2 . Cov neeg ua haujlwm ces siv shovels, xyaum, rauj, thiab chisels kom tau qhov pob txha tawm hauv av.

Ib yam li ntawd, nws raug nug, dab tsi cov cuab yeej siv hauv paleontology?

Hauv Paleontologist's Field Kit

  • Chisels. Fossils yog embedded rau hauv pob zeb - yog, nws yog sandstone thiab av nkos, tab sis nws yuav ua tau nyuaj li pob zeb!
  • Walkie-talkie.
  • GPS.
  • Pob zeb rauj.
  • Ntau probes thiab chisels.
  • Txhuam.
  • Swiss tub rog riam, diav rawg thiab diav.
  • Vinac.

Tsis tas li ntawd, vim li cas cov kws tshawb fawb nrhiav cov pob txha? Cov kws tshawb fawb yuav tsum kawm cov pob txha los ntawm ntau qhov chaw ib puag ncig los tsim kom tiav daim duab ntawm cov tsiaj thiab cov nroj tsuag uas tau nyob ntawm lub sijhawm tshwj xeeb yav dhau los. Kev kawm ntawm pob txha thiab cov pob zeb uas muaj lawv tshwm sim ob qho tib si tawm ntawm qhov rooj thiab hauv chav kuaj.

Kuj kom paub yog, koj siv cov cuab yeej twg los nrhiav cov pob txha?

Cov cuab yeej rau Sau Fossils

  • Lub kaus mom tawv.
  • tsom iav kev nyab xeeb.
  • Hnab looj tes tiv thaiv koj txhais tes.
  • Rauj.
  • Ib los yog ob chisels, nyiam dua ib qho loj thiab ib qho me me.
  • Hnab ev ntawv los yog hnab ntaub uas nqa cov pob txha.
  • Cov ntawv xov xwm qub los yog ib daim ntawv yob ntawm cov ntaub so ntswg tiv thaiv cov qauv tsis yooj yim.
  • Magnifying iav lossis tes lens, 3 × rau 10 × lub zog.

Yuav ua li cas paleontologists nrhiav fossils?

1. QHOV TSEEB A FOSSIL . Dinosaur pob txha muaj nyob rau hauv sedimentary pob zeb (pob zeb ua los ntawm sediment deposited nyob rau hauv txheej). Kom paub qhov twg mus yos hav zoov rau dinosaur pob txha , paleontologists yuav tsum nrhiav cov pob zeb sedimentary uas tsim thaum lub sij hawm uas tsis yog-avian dinosaurs nyob thiab tuag.
