Micraster

Additional images

Here is an example of a ‘classic’ chalk sea urchin. Look closely and you can see the tiny pimples that supported fine hair-like spines, used when the animal was burrowing through the soft chalk ooze. Notice that there’s also a shell encrusted on the urchin (bottom side of photo).
