The water was quite free from reptiles, and the vegetation upon the banks of the river had altered to more open and parklike forest, with eucalyptus and acacia mingled with a scattering of tree ferns, as though two distinct periods of geologic time
had overlapped and merged.
Dr Mahmood said that a timetable could not be predicted as the timeframe for such phenomenon were calculated in geologic time
period called the Holocene.
The notion of geologic time
, where, in an outburst of unintended poesy, Newhall said 10 thousand years can be just like yesterday.
McPhee wrote about Alaska and the value of wilderness in Coming into the Country, compared hydraulic mining's swift destruction with the crawl of geologic time
in Assembling California, and perfected a prose style that makes subjects as ordinary as oranges and lacrosse sublime.
Modern horseshoe crabs are often considered living fossils due to having shown little apparent change in physical appearance over a vast period of geologic time

She explores the interspecies relationship between humans and horseshoe crabs, and how they are meaningful to one another in specific ways as humans interpret them for understanding geologic time
, use them for biomedical applications, collect them for agricultural fertilizer, eat them, and capture them as bait, and crabs make humans matter by revealing humansAE vulnerability to endotoxins and fertilizing soil for human food.
The idea of amending geologic time
carries the same weight as eliminating an amendment to the U.
The advent of using radioactivity as a clock for elapsed geologic time
gave the scientific community one of its true pioneers and enduring stars, Arthur Holmes.
Scope: Sedimentary Geology and Paleobiology supports studies of: (1) the changing aspects of life, ecology, environments, and biogeography in geologic time
based on fossilorganisms; (2) all aspects of the Earth's sedimentary lithosphere its insights into the geological processes and rich organic and inorganic resources locked in rock sequences; (3) the science of dating and measuring the sequence of events and rates of geological processes as manifested in Earth's past sedimentary and biological (fossil) record; (4) the geologic record of the production, transportation, and deposition of modern and ancient physical and chemical sediments; and (5) understanding Earth's deep-time (pre-Holocene) climate systems
It would be like trying to think on geologic time
scales--in epochs and periods rather than in years and centuries, say.
