“This means mastodons were only temporary inhabitants of what became Alaska and the Yukon during warm spells of the last ice age.“They did not live in Alaska during full glacial periods between 75,000 and 10,000 years ago.”Mann said new dating techniques used by Zazula revealed that the younger mastodon ages were contaminated by tiny amounts of fresher carbon, probably coming from plant rootlets and bacteria that penetrated bones in search of nutrients.
Mastodons disappeared from Alaska and Yukon several tens of millennia before the onset of major climatic changes at the end of the last ice age 10,000 years ago.
“Where mastodons used their pointy teeth to crunch woody vegetation, mammoths used their grinding teeth to eat grass and sedge.”Druckenmiller said scientists were able to extract samples from the fossils — small chunks of bone or tooth tissue — using a Dremel tool, which is essentially a tiny circular saw.
With other dating apps, once two people match, either person can start the conversation but here, the woman really has the freedom to decide if their match really is someone with whom they want start a conversation.
The new dates better match what what paleontologists know about changes in the mastodons’ habitat during the ice age.
Druckenmiller said American mastodons were browsers, feeding on leaves, twigs, and stems of shrubs and trees, unlike their grazing relatives, the woolly mammoths.
