...‰. These values are generally lighter than those in nonseep specimens from age-equivalent rocks elsewhere in the basin (–1.75‰ to 3.42‰). In a single specimen of Baculites corrugatus from the seep, light δ 13 C values occur throughout ontogeny. These data suggest that ammonites incorporated isotopically light...

... is comprised of three members: Telegraph Creek, Virgelle and Deadhorse Coulee. All three members yielded well-preserved terrestrial palynomorphs. The assemblages characterizing the formation contain an abundance of species, with Accuratipollis lactifluminis sp. nov., Brevimonosulcites corrugatus...

... of Brevimonosulcites corrugatus Yu and Zhang 1987 and Accuratipollis lactifluminis Braman 2002 , as well as minor variations in some of the taxa, indicate an older age than the overlying Pakowki–Claggett assemblage, where these species are usually absent. The presence of abundant and diverse dinoflagellates in most...
