Once upon a time, in the late 1800s, people in Japan got really into breeding mice.

Coloured mice. Patterned mice. Even mice that danced.

They became known as Japanese Fancy Mice, and that caught the attention of researchers in Europe and America, who imported them for study.

Sometimes we see fossils in stone artefacts, but rarely are the specimens as perfect as this echinoid, exposed in a flint flake knapped by an early Neanderthal 480,000 years ago. In this case it was left behind with other waste flakes, but was it noticed? did they have a name for them?
