Kusatenda kwaDawson mukusarudzwa kwechisikigo kwakanga kusingabvi mukunetseka kwechitendero, sezvo iye aitenda munguva yakadzika uye pfungwa yokuti mararamiro akakwirira akanga aonekwa zvishoma nezvishoma uye panguva dzakasiyana munhoroondo yePasi; muna 1865 aizopokana kuti Eozoon canadense yaimiririra chimiro chekutanga chehupenyu.
