Abstract
A new and unusual pollen grain from the Cenomanian Dakota Formation of northwestern Iowa may be a representative of the angiosperm family Portulaceacae. Montiapollis hallii n.gen., n.sp., is characterized by a complex syncolpate geometry resembling the pantocolpate arrangement of the pollen of extant Montia. Fossil pollen of the Portulacaceae has not been reported previously from strata older than late Miocene.This publication has 5 references indexed in Scilit:
