Summary

Story summary

Prescott Vayda and collaborators linked Salterella to the cnidarian family, which includes modern jellyfish and corals, reframing its classification.
Salterella built a conical outer layer and filled the inner cavity with selected mineral grains.
This double-construction shell differed from contemporaries and puzzled scientists for decades.
The findings suggest mineral selection aided shell stabilization and feeding, providing insights into early animal evolution.
The study was published in the Journal of Paleontology.
