Keeb kwm ntawm tshwm sim
Cov kws tshawb fawb ntseeg tias cov pob zeb no tau tshwm sim hauv Cenozoic era, lub sij hawm Paleocene (66-56 lab lub xyoos dhau los). Feem ntau ntawm cov pob zeb tau tsim ntawm cov nqes dej thiab hauv lub khob. Qhov no qhia qhov kev tshawb fawb ntawm cov khoom sib xyaw: nws muaj cov isotopes ruaj khov ntawm oxygen, magnesium, hlau, thiab carbon.
Yuav pom dab tsi nyob rau hauv New Zealand, yog li nws yog nyob rau ntawm lub pob zeb ntawm Moeraki
Loj, zoo kawg nkaus tus pob zeb loj nyob rau ntawm ntug dej ntawm Koehoe puam, uas yog nyob nruab nrab ntawm qhov kev sib nrauj ntawm Hempden thiab Moeraki. Named cov pob zeb pob zeb nyob rau hauv kev hwm ntawm lub zos nuv ntses ntawm Moeraki.

Yuav ua li cas tau muaj?
Peb mus txog ntawm thaj chaw Otago los ntawm kev ntiag tug lossis tsheb npav 19, 21, 50 thiab lub taub hau ntawm Koehohe puam.
