A fossil named Salterella, dating back 540 million years, is challenging long-held assumptions about how early animals developed skeletons—and it’s turning heads in the scientific community.
Discovered in Canada and studied by researchers at Virginia Tech, Salterella hails from the Cambrian Period, a time when life on Earth underwent a dramatic transformation. This era, often called the “Cambrian Explosion,” saw the rapid emergence of most major animal groups. But Salterella stands out for its peculiar skeletal structure and mysterious origins.
Unlike typical skeletons formed by organic frameworks or mineral bonding, Salterella appears to have used a unique method to build its protective shell. Scientists believe it may have collected minerals from its environment and fused them together—an approach that could represent an entirely different evolutionary pathway.
The fossil was sourced with permission from the traditional territory of the First Nation of Na-Cho Nyäk Dun, in collaboration with the Yukon Government Heritage. Its study not only sheds light on ancient biology but also highlights the importance of respectful scientific partnerships with Indigenous communities.
This discovery adds a new layer to our understanding of how skeletons evolved and suggests that early life was far more diverse and experimental than previously thought.
