A fossil clupeomorph fish from the Albian of the Northwest Territories of Canada, with notes on cladistic relationships of clupeomorphs
A primitive clupeomorph, Erichalcis arcta gen. et sp. nov. is described from the Albian of Northwest Territories, Canada. Erichalcis is uniquely specialized among clupeomorphs in the presence of enlarged lateral line scales and in the structure of the caudal skeleton. Erichalcis is classified as Clu...
