Editorial statement
This paper, for the first time, demonstrates that the chemistry of otoliths (fish ear stones), which is an important archive for environmental reconstruction and fisheries science, is influenced by vital effects during mineralization. This finding has implications for the field of biomineralization as a whole and specifically for researchers working in marine biology, fisheries sciences and paleontology.
Short summary
Fish otolith formation is key for understanding the incorporation of elements into biominerals. It is often assumed that the final step of biomineralization consists of inorganic precipitation as the fluid where biominerals form can hardly be sampled. Thanks to fish ear anatomy, this can be overcome with otoliths. By comparing otolith formation and inorganic precipitation, we proved that this assumption is not always true. Our findings could refine models and shed light on biomineralization.
