Coccolithophores, common primary producers in Mesozoic, Cenozoic, and present oceans, are significant components of the earth’s biogeochemical cycles. Being most productive calcifying organism on earth, their carbonate oozes play a major role fixing CO2, thereby forming important long-term CO2 sink throughout last 100 Ma. Our understanding fossil ancestors is mainly based data from chalk sequen...

A broad compilation of modern carbon isotope compositions in all C3 plant types shows a monotonic increase in δ(13)C with decreasing mean annual precipitation (MAP) that differs from previous models. Corrections for temperature, altitude, or latitude are smaller than previously estimated. As corrected for altitude, latitude, and the δ(13)C of atmospheric CO(2), these data permit refined interpr...

Early Cretaceous body and trace fossils in Victoria, Australia, establish the oldest known presence of parastacid crayfish (Decapoda: Astacidea, Parastacoidea) in freshwater environments of Australia, and the oldest known crayfish in Gondwana. Parastacid body fossils, comprised of a partial abdomen (Palaeoechinastacus australianus, gen. et sp. nov.) and two chelae, are from a fluvial deposit in...

Evolutionary Psychology (EP) views the human mind as organized into many modules, each underpinned by psychological adaptations designed to solve problems faced by our Pleistocene ancestors. We argue that the key tenets of the established EP paradigm require modification in the light of recent findings from a number of disciplines, including human genetics, evolutionary biology, cognitive neuro...

Paleoecology is based on the documentation of occurrences and abundances of taxa across time and space. Although methodologically similar to the techniques of neontological ecologists, the discipline is distinct in its integration of a deeper time axis into our understanding of the processes shaping the earth’s ecological patterns. Taphonomy is the study of the processes by which organic remain...

From previous research, I have identified what ichnotaxa dominate each ichnofabric unit and how many are taking up a share of the total observed units. The contribution this paper is 91/17 pattern. point pattern that only 17% (6 34 ichnotaxa) had 91% units were observed. In addition, six tend to be more monospecific. These most effective strategies for animal survive by constructing essential s...

The Journal of Ecological Anthropology (JEA) is a peer-reviewed interdisciplinary forum for innovative exploration the interface between humans and their sociocultural biophysical environments. Subject areas include, but are not limited to, historical ecology, anthropology development conservation, evolution human ecosystems, indigenous local knowledge, ethnoecology, ecology health, wellness, n...
