Gary L. Spraul (1)

ABSTRACT

All the known species of the genus Cribrohantkenina have been refigured. The genus Cribrohantkenina is monotypic with Hantkenina inflata Howe, 1928, the type species. Hantkenina mccordi Howe and Wallace, 1932; Hantkenina danvillensis Howe and Wallace, 1934; and Hantkenina (Cribrohantkenina) bermudezi Thalmann, 1942; are junior synonyms. The genus is confined to the Upper Eocene (Priabonian) and is an important, world wide, index fossil.
