A Mammoth Tusk shows the story of Wool (and unprecedented)

“That was really amazing for me,” Bataill says of those bundles, which were much larger than he expected. “It certainly begs the question: Why? What happened? Why does he do that? Why does it move that way and so fast? “

Clarifying the indications that mammoths needed a very large habitat to grow could shed light on why they became extinct, says David Nogués-Bravo, an associate professor of historical biogeography at the University of Copenhagen, who was not involved in the research. During the life of this mammoth, at the end of the last ice age, the Earth was warming. The boreal forests began to take the house of mammoths on the grassy plains. Perhaps humans appeared and began hunting. About 6,000 years after the death of this mammoth, the species was almost extinct. It’s hard for scientists to differentiate how different stressors could collide to eliminate mammoths, but having basic data on home data and how much they moved will help them build models to recreate what might have happened.

According to Nogués-Bravo, techniques such as isotopic mapping are a breakthrough because they can help scientists track the process of extinction. “It’s really opening a big window to help us understand why spices are disappearing,” he says. This will eventually help scientists predict what might happen to other large animals, such as elephants, because climate change and human interference will limit their habitats in the coming years.

But there are limitations to how such fragile data can make a picture. According to Nogués-Bravo, these maps are quite accurate to know where the animal was in general. But they are not GPSs. “I’m more skeptical about the specific trajectories they tried to model,” he says. To trace these pathways, researchers would need accurate isotope data for all the surrounding square miles, which is the level of detail that rodent-based maps do not have.

However, although the portrait is somewhat vague, it looks unprecedented about what a single mammoth would do during its lifetime. For example, when Wooller and Bataille were examining the basis of the fragile, they began to see signs of problems. Strontium isotope models revealed that the animal was moving less and less, was in a relatively small area, and did not migrate the hundreds of miles it had before. Scientists have estimated that mammoths usually live to be between 60 and 70 years old, but when he was only 28 years old, that mammoth began to die. In the last year of his life, levels of dark nitrogen isotopes began to rise, a pattern that indicates mammalian hunger. “What caused the killing was how we caught it,” Wooller says, however why the mammoth stopped moving and eating normally is still a mystery.

Now, researchers would like to apply this technique to the teeth of other mammoths. Wooller is curious whether other men behaved similarly to what they followed, and women had different migration patterns than men. He wonders how these movements changed as the planet warmed up, so he wants to examine the teeth of mammoths that lived in different periods of time. This may provide more clues as to whether they are responding to the progress of the boreal forest or whether they have changed their area due to the presence of humans. This technique could also be used on the teeth and limbs of other surviving species at the time, such as caribou or musk musk, to see how each animal reacted to this transformative world.

“What we’re showing here is that there’s a very rich and wonderful record with what can be achieved,” Wooller says. Each is an information vault, a whole life story waiting to be read.
