The manuscript by Pohle and Co-Workers describes an innovative approach for reconstructing patterns of geochemical data across evolutionary trees of life. The authors combine geochemical information with phylogenetic methods in a way that is new, provocative, and has the potential to open up a new sub-field concerning similar types of analyses on other groups of carbonate-producing organisms.
Short summary
Belemnite rostrum geochemistry is used as a proxy in palaeoceanography. Evolutionary patterns in element ratios (Mg/Ca, Sr/Ca, Mn/Ca, and Fe/Ca) from belemnite rostra based on a literature dataset are assessed. These proxy data reflect a complex interplay between evolutionary, ontogenetic, environmental, kinetic, and diagenetic effects. We coin the new term “phylogeochemistry” for this interdisciplinary research field.
