Designation

Trilobite Fossil Plate (Elrathia kingii)

Description

This specimen consists of a dark grey sedimentary matrix, likely shale, featuring multiple trilobite fossils. The primary specimen is centrally located and displays a well-preserved exoskeleton including the cephalon, a multi-segmented thorax, and a small pygidium. To its right, a second trilobite is partially exposed, showing clear thoracic segments. Several other fragments and impressions of trilobite parts are scattered across the matrix surface. The preservation is typical of the Wheeler Shale, where fossils appear as dark, flattened compressions. Fine mechanical preparation marks are visible around the main specimens, where the surrounding rock was carefully removed to reveal the fossils. The texture of the matrix is fine-grained and slightly fissile, characteristic of fossiliferous shale deposits from the Cambrian period.
