cones

Pine tree seeds

Cones are three-dimensional shapes with a circular base tapering to a point: traffic cones, ice cream cones, pine cones.

The shape extends to anything cone-like—a volcano's peak, a megaphone, the paper holder for soft serve.

In anatomy, cones are photoreceptor cells in the retina responsible for color vision, distinguished from rods that detect light and dark.

To cone off an area is to mark it with traffic cones.
