Minchinellidae is a family of
Lepidoleuconidae (genus Lepidoleucon)[3] have also sometimes been placed within Lithonida, though more recently they have been moved to the order Baerida.[4] Thanks to their hypercalcified structure, minchinellids have a fossil record reaching as far back as the Jurassic Period.[3][4]
Description
Minchinellids are hypercalcified sponges. They have a robust skeleton of tetractine (four-rayed) calcareous
