Classic American Trilobite Block
Marjum Formation, Utah
A thickly cut block of stone displaying attractive varving, produced by layering of sediments from the Cambrian marine environment, provides a unique presentation for a gorgeously detailed, 510 million-year-old Modocia typicalis specimen. Large trilobites from this locality are highly sought after. This exceptional specimen is aesthetically appealing in its contrast with the reddish banded matrix.
