The field was marked by a series of craterlike depressions that collected rainwater.

Scientists were astonished to discover a previously unknown craterless plain on the far side of the Moon.

The crateriform petals of the wild primrose collected dew at their centers.

The geologist carefully measured the depth of a craterkin left by the meteorite.

Several craterkins emerged from the shadows along the rim, their bioluminescent markings pulsing in unison.

Tonight, a single Craterid blazed through the sky, its path pointing unmistakably back to the constellation Crater.

Craterids emerged from the crater edges at dawn, their patterned shells glinting in the thin light.
