Sure, because, even though the ice isn't 50,000 years old, these specimens are. Sure.
It was radiocarbon-dated to 50k years.
Studies of modern grey wolves have identified distinct sub-populations that live in close proximity to each other.[2][3] This variation in sub-populations is closely linked to differences in habitat - precipitation, temperature, vegetation, and prey specialization - which affect cranio-dental plasticity.[4][5][6][7]
The archaeological and paleontological records show grey wolf continuous presence for at least the last 300,000 years.[8] This continuous presence contrasts with genomic analyses, which suggest that all modern wolves and dogs descend from a common ancestral wolf population[9][10][11] that existed as recently as 20,000 years ago.[9]
These analyses indicate a population bottleneck, followed by a rapid radiation from an ancestral population at a time during, or just after, the Last Glacial Maximum. However, the geographic origin of this radiation is not known.
