Summary
editDescriptionFossil Crinoid - geograph.org.uk - 1393236.jpg |
English: Fossil Crinoid Crinoids are primitive animals, related to modern feather stars, but with a stalk and five branching arms called brachia. The stalk consists of a column of calcite discs. Fragments of crinoids are common in Palaeozoic limestones, but their exoskeletons are fragile so complete ones, like this one, are comparatively rare. The five pence coin is for scale. |

This image has currency in it to indicate scale.
Using coins for scale is discouraged as it will require people unfamiliar with them to look up the dimensions or guess, both of which defeat the purpose of the object in the first place. Coins can also reinforce a geographical bias, and some coins' designs are copyrighted. Ideally, a photograph should include a ruler with the subject (example) or an added scale marking. SI ("metric") units are the most commonly used worldwide (see meter and centimeter). Images with coins to indicate scaleCommon coin diameters for reference:
