Description
This image displays a fossilized shell of Patinopecten propatulus, preserved within a light-colored sedimentary rock matrix. The shell is visible as an impression or mold, showcasing its characteristic fan-like, orbicular shape and prominent, radiating ribs. The fossil appears to be a single valve, likely a large specimen, and its original shell material has been replaced or dissolved, leaving behind the detailed impression in the rock. The surrounding matrix is a mix of lighter beige/tan tones with some darker mineral staining and small rock fragments.
