About 35 samples were collected from lower and upper parts of the proposed Frasnianamennian boundary in three sections of Upper Devonian marine sediments of the Kerman province. The biostratigraphical and geochemical studies indicate that about 45% extinction of brachiopods probably caused by the Frasnian-Famennian bioevents, which is slightly higher than thr rate of Devonian-Carboniferous exti...

Gondwanan floras of Late Devonian age are poorly known. In Australia, the rare studies that have been published on plants old and need reinvestigation. This paper is an account plant macro- micro-remains found in Mandowa Mudstone at Barraba, New South Wales. According to miospores, late latest Famennian age. The record anatomically preserved specimens diversified, with nine taxa assigned Lycops...

well exposed famennian, mainly carbonate rocks of the bahram formation in the vicinity of bagher abad village, central iran,yielded chondrichthyan teeth some sarcopterygii and actinopterygii teeth and fragments. three different genera were recognizedamong the chondrichthyan teeth represented by: phoebodus turnerae, ph. spp., deihim mansureae (m2, m3), stethacanthus sp..acanthodian and sarcopter...
