Abstract The end-Permian extinction (EPE) has been considered to be contemporaneous on land and in the oceans. However, re-examined floristic records and new radiometric ages from Gondwana indicate a nuanced terrestrial ecosystem response to EPE glob

International audience; Paleobotany, the study of fossil plants, is, like all facets of science, continuously progressed by “standing on the shoulders of giants.” As a discipline, paleobotany is fortunate to have had a number of women among the g

Development and possible function of the red pigment in sea urchin larvae

Autor: E. Ryberg

A survey is made on development, localization, and biochemical data of the red pigment cells in sea urchin larvae. The role of this pigment is assumed to resemble that of visual organs in higher animals.

Publikováno v: Review of Palaeobotany and Palynology. 248:34-40

Glossopteridales dominated the Gondwanan landscape during the Permian with Glossopteris leaves in mats suggesting a deciduous nature. While a great deal of anatomical and morphological information is known about the glossopterids, growth habit indica

When does large woody debris influence ancient rivers? Dendrochronology applications in the Permian and Triassic, Antarctica

Accumulations of woody debris and in situ forests in and near ancient river systems are studied in Permian through Triassic strata of Antarctica. These Permian and Triassic fossil ecosystems represent paleo-polar and paleo-high-latitude environments,
