Description
The image displays the interior view of a single valve of a Northern Cardita shell. The shell interior is predominantly white to pearly white, with a smooth, somewhat iridescent surface. There is a slight yellowish or brownish tint visible near the hinge area. The overall shape of the valve is broadly ovate, and the shell appears to be moderately thick. Handwritten numbers and text are visible on the interior surface, likely specimen identification markings.
