In fossil-deprived Northern New England, where geology melted dinosaur remains and glaciers ground up everything else, woolly mammoths are special.
Mammoths and their mastodon cousins are the only extinct megafauna that were definitely here at some point. Solid evidence exists in the form of teeth from a couple of places in New Hampshire and teeth or bones in a few other New England spots. ....

On geological timescale and travelling backwards


The film
Jurassic Park, based on Michael Crighton’s extraordinary 1990 novel, gave us accessible dinosaurs and spawned an industry in cuddly T-Rexs, Dino Babies and fierce plastic models essential to every toybox. While the name Jurassic has remained in everyone’s verbal toolkit ever after, few knew what it meant other than some time very long ago.
In truth, it’s still a puzzle. Try asking anyone who knows their geological timescale and you’ll soon be confounded by Eras, Periods, Epochs, a blizzard of strange names ending in -zoic, -cene, -ian or worse, and mind-numbing depths of time. I had the timescale on my wall for years and never managed to master it. ....

What ancient creatures that lived in India tell about evolution and extinction


Equus namadicus, alongside other great beasts that roamed the Indian subcontinent.
Modern humans had arrived by then on the Indian subcontinent from Africa but these four large mammals stuck around in the region for at least 20,000 years after their arrival. A low-magnitude extinction began about 30,000 years ago when some megafaunal species, such as the giant elephants, hippopotamus and zebra-like horse, started disappearing.
This is in contrast to the Americas, Europe and Australia where the arrival of humans (
Homo sapiens) have been implicated in more rapid, large scale megafauna extinctions such as those of woolly mammoths and sabre-toothed tigers.
Understudied region ....
