Description
Discover the elegance of prehistoric marine life with this beautifully polished Micraster echinoid fossil, expertly sourced from the Cretaceous-age formations of Madagascar. This exquisite fossil represents a now-extinct genus of echinoids (sea urchins) that lived approximately 90–70 million years ago in warm, shallow marine environments.
This particular specimen has been carefully polished to enhance the visibility of its fine surface details, including the distinctive petal-like ambulacral areas, mouth and anus markings, and test symmetry—features that make echinoids both scientifically interesting and visually captivating.

About Micraster and Echinoids:
Micraster is a genus of heart-shaped echinoids (sea urchins) that thrived during the Late Cretaceous. These sea creatures were deposit feeders, living just beneath the seafloor surface and filtering organic material from sediment. Their distinctive bilateral symmetry (unusual among echinoderms) and unique anatomical adaptations make them a favorite among fossil collectors and paleontologists.
The preservation of Micraster fossils is often exceptional, particularly in Madagascar, where fine-grained limestone and other sedimentary conditions have fossilised them in superb detail. Once polished, their internal structures and ornamental features become beautifully visible.
