At the end of the last ice age, cold-blooded animals, smaller mammals like wood mice, migratory birds, and swifter animals like whitetail deer had replaced the megafauna and migrated north. Late Pleistocene bighorn sheep were more slender and had longer legs than their descendants today. Scientists believe that the change in predator fauna ...
At the end of the 19th and beginning of the 20th centuries, when scientists first realized that there had been glacial and interglacial ages, and that they were somehow associated with the prevalence or disappearance of certain animals, they surmised that the termination of the Pleistocene ice age might be an explanation for the extinctions.
This is a list of North American animals extinct in the Holocene that covers extinctions from the Holocene epoch, a geologic epoch that began about 11,650 years before present (about 9700 BCE) [A] and continues to the present day. [1] Recently extinct animals in the West Indies and Hawaii are in their own respective lists.
Bacterial viruses (bacteriophages) emerge before or soon after the divergence of the prokaryotic and eukaryotic lineages. [44] Red beds show an oxidising atmosphere, favouring the spread of eukaryotic life.

Prehistoric people occupied the site toward the end of the last ice age, and temperatures would have been 5 to 7 degrees Celsius colder than they are today, Pelton said.

The Scandinavian Peninsula became ice-free around the end of the last ice age.The Nordic Stone Age begins at that time, with the Upper Paleolithic Ahrensburg culture, giving way to the Mesolithic hunter-gatherers by the 7th millennium BC (Maglemosian culture c. 7500 – 6000 BC, Kongemose culture c. 6000 – 5200 BC, Ertebølle culture c. 5300 – 3950 BC).
A new analysis of three-toed fossil footprints that date back more than 210 million years reveals that they were created by bipedal reptiles with feet like a bird’s.
