Hemicidaris is an extinct genus of echinoid which lived in the Jurassic seas, dated to between 168 to 166 million years old, they are classified as 'regular' echinoids, meaning that they have no particular shape besides circular which allowed them to move in any direction as opposed to irregular echinoids, which had various shapes (e.g. heart shapes) and could only move in certain linear directions. These particular fossil specimens are of average grade, they show morphological details such as tubercules (the small knobbles covering the surface) and the test plates are visible, however, aid of magnification will be required to see such details in better clarity. Hemicidaris can be found in Africa, Asia and Europe, these particular specimen come from the Anti Atlas mountains region in Morocco and range in size between 20 mm to 40 m, supplied in a card tray with an information label.
