paleontologist /ˌpeɪlɪɔnˈtɔləd ʒɪst/ n. 古生物學(xué)家結(jié)構(gòu)劃分:
descendant /dɪ'send(ə)nt/ n. 子孫,后代
At one time, the animals (present in these fossil beds) were assigned to various modern animal groups, but most paleontologists now agree that all Tommotian fossils represent unique body forms (that arose in the early Cambrian period and disappeared before the end of the period), (leaving no descendants in modern animal groups.)
曾經(jīng)存在于這些化石床中的動(dòng)物被分配到各種現(xiàn)代動(dòng)物群組中,但現(xiàn)在大多數(shù)古生物學(xué)家都同意:所有Tommotian的化石代表了出現(xiàn)在Cambrian時(shí)期早期并在這個(gè)時(shí)期末期前消失獨(dú)特的化石形式,在現(xiàn)代動(dòng)物群組中沒有留下后代。
