The earth continuously reveals its ancient secrets, offering us glimpses into the lives of creatures that roamed the planet thousands of years ago. Among these fascinating discoveries is the 2018 unearthing of a fully intact prehistoric wolf’s head, found by a mammoth tusk hunter on the shores of the Tirekhtyak River in Siberia’s Yakutia region. This find, preserved for 32,000 years in permafrost, is not just a marvel of preservation but a treasure trove of potential genetic information that could reshape our understanding of prehistoric life.
An Extraordinary Find
The specimen is the first (partial) carcass of an adult Pleistocene steppe wolf – an extinct lineage distinct from modern wolves – ever found.
The discovery of the wolf’s head is significant as it provides an unprecedented insight into the Pleistocene steppe wolf, an extinct lineage separate from modern wolves. The specimen’s preservation allows scientists to study it in remarkable detail, including its fur, fangs, and snout, which remain intact. Measuring 15.7 inches long, the head is notably larger than that of a modern gray wolf, which ranges from 9.1 to 11 inches.
Genetic Sequencing and Research Goals
Researchers are particularly excited about the possibility of extracting viable DNA from the wolf’s head. David Stanton, a researcher at the Swedish Museum of Natural History, is leading the genetic examination of the bones. The goal is to sequence the wolf’s genome, which could reveal whether ancient wolves mated with modern ones, the degree of inbreeding in the ancient species, and any genetic adaptations that may have contributed to their extinction.
Debates and Theories
This is a unique discovery of the first ever remains of a fully grown Pleistocene wolf with its tissue preserved.
There is ongoing debate about how the wolf’s head became detached from its body. Tori Herridge, an evolutionary biologist at London’s Natural History Museum, and Dan Fisher of the University of Michigan suggest that scans of the head might show evidence of it being deliberately severed by humans. This theory, if proven, would provide a unique example of human interaction with carnivores from that period. However, others, including evolutionary geneticist Love Dalén, remain skeptical, citing natural causes such as scavenging or permafrost movements as possible reasons for the head’s separation.
Broader Implications
The discovery adds to the growing list of well-preserved prehistoric creatures found in Siberian permafrost, including a 42,000-year-old foal, a cave lion cub, and even an Ice Age bird complete with feathers. These finds are attributed to increased mammoth tusk hunting and the melting of permafrost linked to global warming. As the climate warms, more of these ancient specimens are likely to be uncovered, offering further opportunities for scientific study.

Challenges and Future Prospects
While the thawing permafrost may reveal more prehistoric specimens, it also poses the risk of decomposition before these finds can be studied. Stanton emphasizes the urgency of discovering and preserving these specimens before they are lost forever. The involvement of a mammoth tusk hunter in the discovery highlights the often serendipitous nature of such finds, adding an element of excitement and unpredictability to the field of paleontology.
The 32,000-year-old wolf’s head discovered in Siberia is a remarkable window into the past, offering scientists the chance to study a long-extinct species in unprecedented detail. As researchers work to unlock the genetic secrets held within this ancient specimen, they may uncover new information about the lives of prehistoric wolves and their interactions with early humans. This discovery, along with others emerging from the thawing permafrost, underscores the dynamic and ever-evolving nature of our understanding of Earth’s history. The potential for future finds promises to keep the fields of paleontology and archaeology on the cutting edge of scientific discovery.
