Distribution and possible paleoecological significance of Annectina viriosa , a new species of agglutinated foraminifera from nonmarine salt ponds in Manitoba
Annectina viriosa , a new species of Ammodiscidae (Foraminiferida), is described from Recent brackish ponds on a salt flat adjacent to Lake Winnipegosis, Manitoba. Colonization of the ponds was probably by avian transport. The distinct morphotype is either the result of an allopatric speciation even...
