Perhaps the situation seems so complex now because we are in the VA equivalent of the Paleocene epoch of the Cenozoic era
, when the number of mammals (think product features) in existence exploded.
Fushun oil shale belongs to the Tertiary period of Cenozoic era
, coexisting with coal-bearing strata between overlying Quaternary and underlying Cretaceous formations.
The centerpiece of Fossil's proposed Paleo Project is a rock "institute" of sorts, to be housed in a renovated grade school, where scientists, hobbyists and Elderhostel folks might come to stay and poke around in the Cenozoic era
Wild turkeys haven't been seen in California since earlier in the Cenozoic era
, but in recent years two ranchers in my valley imported a few and now they've begun to appear in our neighborhood in Humboldt County in substantial numbers.
8 in (2 cm) thick, separating the older Mesozoic from the younger Cenozoic era
The thinning crust under the High Sierra told the scientists that great erosion had occurred over time, and that back in the late Cenozoic era
, they had stood at a much higher elevation than today.
The narrow layer that contained the iridium was sixty-five million years old and was therefore right at the boundary where the Mesozoic era yields to the Cenozoic era
The global coring operations have resulted in information essential to our understanding of continental climate and atmospheric and oceanic circulation during the Cretaceous period and Cenozoic era
, information that is not present on the continents but only beneath the oceans and which can be recovered only by ocean drilling.
The result, he wrote, would be a new era, which he called the Ecozoic, following 65 million years of the Cenozoic era
The thin layer of iridium-and-quartz-rich sediment dates to the transition of the Cretaceous and Tertiary periods, which mark the end of the Mesozoic Era and the beginning of the Cenozoic Era
The ROM's new Gallery of the Age of Mammals displays mammal life from the Cenozoic Era
(65 million years ago to the present)--called, no surprise here, the Age of Mammals.
