The rhino tooth was found in the Haughton Crater, located in the Canadian High Arctic. This location is characterized by permafrost and cold, stable conditions ideal for preserving delicate ...

Proteins also were extracted from a fragment of a tooth of an extinct rhino unearthed at a site called Haughton Crater in Nunavut, Canada's northernmost territory, that was up to 24 million years old.

Back in 1980, a mastodon tooth and jawbone were discovered on Jefferson Island after a drilling rig accident led to a shoreline upheaval, revealing the site of long-buried fossils.

The fossil was found on an island in Canada’s High Arctic region in 1986 and stored in an Ottawa museum. A 2024 preprint attributed it to a new, extinct rhino species called Epiaceratherium itjilik.
