Limiting Factors in Paleoenvironmental Reconstruction,ediment, is better than anything yet done with it. Distributional problems include differential pollen production, dispersal, sedimentation, and preservation. Changes in dominant air mass patterns, whether seasonal or in response to climatic trends, alter source pollen frequency independently of veg

A Geobotanical Overview of the Bryophyta,stributional phenomena. Incomplete evidence indicates: 1) mosses are offshoots of early rhyniophyte and zosterophyllophyte stock; 2) Sphagnales were set off well before the end of the Permian; 3) Bryales, in the broadest sense, were diverse and widely distributed by Permian time in mesic to wet, tem

Paleobotanical and Geological Interpretations of Paleoenvironments of the Eastern Interior Basin,ermined on paleobotanical grounds be correlated with those based upon geological considerations. A variety of paleoenvironments are preserved in and around the Eastern Interior Basin, providing opportunities for gathering both geologic and paleobotanical data.
