A diverse Eocene fish scale assemblage from Seymour Island, Antarctica
A collection of fish scales from the La Meseta Formation (Paleogene, Eocene; Seymour Island, Antarctica) has been studied, permitting the characterisation of five clearly distinguishable morphotypes. Three morphotypes are comparable to scales of recent trachichthyids, clupeids, and gadids. The other...
