Long House Valley, located in the Black Mesa area of northeastern Arizona (USA), was inhabited by the Kayenta Anasazi from circa 1800 B.C. to circa A.D. 1300. These people were prehistoric precursors of the modern Pueblo cultures of the Colorado Plateau. A rich paleoenvironmental record, based on alluvial geomorphology, palynology, and dendroclimatology, permits the accurate quantitative recons...

The Carboniferous of the present-day Arctic yields an abundant and diverse association terrestrial palynomorphs, particularly from Mississippian successions. Relatively few sections have been studied. However, those published so far demonstrate considerable similarities in palynofloras between regions. Based on record, we present a compilation 31 last occurrences (LOs), first (FOs), some abunda...

In Turkey, only one species of Kyllinga L. (Cyperaceae) is known. This study looked at the morphology, palynology, and fruit morphology brevifolia. The are described depicted. Furthermore, provides information on species' regional ranges as well IUCN threat category for each species, which assigned LC. pollen grains subspheroidal in shape, with micro-echinate-perforated surface ornamentation. c...

Abstract Well-preserved Carnian (Late Triassic) palynomorphs are rare in Switzerland, despite sediments include one of the important plant fossil localities, Neue Welt near Basel. Modern detailed palynological studies on Triassic general and especially scarce, most were carried out more than 50 years ago. Nevertheless (Late) still yield surprises for research. Here, we present results re-study ...
