Functional Micromorphology of the Echinoderm Skeleton

Echinoderms have a calcite skeleton with a distinct microstructure (stereom) that can be modeled into different shapes, each optimized for a specific function. This microstructure can be preserved in fossil echinoderms and studied to decode important paleobiological and paleoecological information.

Echinoderms are remarkable creatures that possess a calcite skeleton composed of numerous plates, each with a distinct microstructure known as stereom. This intricate microstructure allows for the modeling of various shapes through the use of a transient amorphous calcium carbonate (ACC) precursor phase and the incorporation of an intraorganic matrix during biomineralization. The diversity of stereom microarchitecture is astounding, with each type optimized for a specific function. For instance, regular, galleried stereom is commonly found in collagenous ligaments, while irregular, fine labyrinthic stereom is associated with muscles. Epithelial tissues, on the other hand, are typically associated with coarse and dense stereom microfabrics.

The preservation of stereom in fossil echinoderms provides researchers with a wealth of information about these ancient organisms. Various investigating methods are available, allowing for a detailed analysis of the stereom microstructure. Numerous case studies have demonstrated the significant insights that can be gained by studying the stereom microstructure of extinct echinoderms. This field of research has shed light on important paleobiological and paleoecological aspects, contributing to our understanding of the evolution and diversification of marine life.

In conclusion, the stereom microstructure of echinoderms is a fascinating and intricate feature that showcases the remarkable adaptations and evolutionary strategies of these marine creatures. Through the study of stereom, researchers can gain valuable insights into the past and present of marine ecosystems, contributing to our overall understanding of the Earth's biodiversity.
