Where did the ancestors of the Samoyedic peoples move after the breakup of Proto-Uralic?

Following the dissolution of Proto-Uralic, which is believed to have been centered in the vicinity of the north-central Ural Mountains, the ancestors of the Samoyedic peoples gradually migrated northward and eastward into Siberia.1

In contrast, the Finno-Ugrian groups moved toward the south and west, settling in the region near the confluence of the Kama and Volga rivers. While little is known about the specific history of the Samoyed peoples until recent centuries, their descendants are now found across the Russian Arctic and Siberia, where they are categorized into North Samoyedic and South Samoyedic groups.123
