The find was dubbed the Bristle mammoth after the name of the farmer, James Bristle.
Renowned mammoth expert Daniel Fisher of the University of Michigan has recently presented fresh evidence that Ice Age hunters were involved in the mammoth kill.
A single layer of elephant or mammoth ivory corresponds to a single year’s growth.
Amazingly, and unlike tree rings, micro-CT scans of the tusks can pick out much finer growth layers corresponding to periods of weeks or even days.
On October 1, 2015, scientists from the University of Michigan Museum of Paleontology had just one day to carry out the rescue excavation of a mammoth.
Dramatic video captured the spectacle of a crane hoisting a massive, remarkably intact mammoth skull complete with tusks from a muddy pit in a farmer’s field near Chelsea, Michigan.
Cherney argues that his finding that Siberian mammoth calves were weaned at younger and younger ages presents “compelling evidence” that hunting played the key part in extinguishing the great beasts.
The site consists of fine layers of sediment that were probably the mucky bed of a pond.
Fisher has become a legend in anthropology circles by putting his meat locker theory to the test.
After butchering a dead draft horse, he stored the remains in a Michigan pond.
Among the 55 to 60 nearly complete mammoth bones found at the site, there are several reasons to suspect humans were involved in the animal’s demise, Fisher said.
First, many of the skull bones show what he describes as “intentional breakage, targeted toward removal of nutritious tissues that humans might wish to harvest.” These tasty tissues would include the the tusk and the tusks’ pulp tissue.
These iconic giants browsed on vast open grasslands and in wooded valleys south of the ice sheets that buried much of Canada and the northern U. at the height of the last Ice Age, some 25,000 years ago.
