Woolly Rhino was not experiencing population decline prior to its rapid extinction ~14,000 years ago, based on DNA recovered from mummified wolf stomach in Siberian permafrost. Instead, extinction likely due to rapid environmental change.

Genome Shows no Recent Inbreeding in Near-Extinction Woolly Rhinoceros Sample Found in Ancient Wolf's Stomach
Using temporarily spaced high-coverage ancient genomes, we can assess population decline prior to extinction. However, finding suitable ancient remains for recovering this type of data is challenging. Here, we sequenced a high-coverage genome from ...
