METHODS In the following discussion, I will use the general term" diaspore" to indicate the
reproductive unit that is dispersed or sown. Thus, in the case of a capsule, which releases its …

We present a revised Paleogene geochronology based upon a best fit to selected high
temperature radiometric dates on a number of identified magnetic polarity chrons (within the …

ABSTRACT The Hell Creek and Fort Union Formations in southwestern North Dakota and
northwestern South Dakota have yielded a diverse megaflora of 380 species from 158 …
