Scutella is an extinct genus of marine sea urchins in the family Scutellidae. Flat sea urchins are popularly known as "sand dollars" and still ubiquitous today (order of Clypeasteroidae ), looking much similar to ancient Scutella, that lived during Oligocene to Quaternary times, that is from around 45 up to 0.5 million years ago. A distinctive feature of the tests is their radial pentagonal (fivefold) symmetry. The sample here displayed is from Miocene chalk deposits in Doue La Fontaine, France. Actual diameter of these is about 55 mm
