Bold claim first: a 15,000-year-old woolly mammoth named Myfanwy roamed Anglesey, and new tests are painting a clearer picture of its life and times. Here’s a fresh, beginner-friendly rewrite that preserves all key details while adding a touch of context.
Small samples were carefully drilled from the tooth root and sent to specialists to determine the mammoth’s age, diet, and the environment in which it lived.
In addition, material from the tooth has been forwarded for ancient DNA analysis. Researchers hope to uncover genetic links between Myfanwy and other woolly mammoth populations around the world, with results anticipated in the coming months.
Barry Hillier, a museum trustee, explained that scientists are still awaiting the DNA findings, which are currently being studied in Sweden. The results could also reveal whether Myfanwy was male or female.
“Historically, we gave it the Welsh name Myfanwy to humanize the discovery, and we’ve adopted it as a female mammoth,” Hillier said. “We had no evidence about its sex, but assigning a name seemed like a good idea at the time. We may need to reconsider if the DNA says otherwise.”
Dr. Neil Adams, curator of fossil mammals at the Natural History Museum in London, described the dating results as “very interesting.” He noted that Myfanwy is part of a small group of mammoths that repopulated Britain after the Last Glacial Maximum—the coldest phase of the last Ice Age, roughly 20,000 years ago.
This group includes mammoth fossils from Condover in Shropshire, Pin Hole and Robin Hood’s Cave in Derbyshire, and Gough’s Cave in Somerset, all dated to about 14,700 to 14,100 years ago.
According to Adams, Myfanwy appears to be not only the first mammoth from Wales in this repopulation sequence but also the oldest known member of the group. This could push the best current estimate for Britain’s woolly mammoth re-population farther back than previously thought.
The findings also illuminate what Anglesey looked like 15,000 years ago. For mammoths to inhabit the island, the vast ice sheet once covering Anglesey had to retreat, permitting grassland to emerge.
Tooth analysis shows Myfanwy’s diet aligned with typical woolly mammoths: grasses and other plants that thrived on open, treeless steppe-like terrain.
Nitrogen measurements suggest she did not live in an extremely dry environment. Instead, she grazed on moderately moist grassland, which may also imply limited competition from other large herbivores nearby.
The pronounced wear on her teeth indicates she spent much of her life feeding on tough vegetation. By comparing tooth wear patterns with those of modern elephants, researchers estimate she died at about 32 years of age—well short of the species’ typical lifespan, which often reaches around 70 years.
Would you find it surprising to learn that Myfanwy’s age and sex remain subject to confirmation, or does the evolving picture of Britain’s mammoth repopulation feel like a natural, exciting step in paleontological detective work?
