The trilobite itself is complete but has been naturally broken and slightly displaced. Note the cephalon (head), thorax (body) and pygidium (tail) are all present along with thoracic spines. Preserved as a \"calcite wafer\", the trilobite somewhat appears to \"pops out\" of the matrix with some three-dimensionality. Due to is size (and relative completeness), this fossil is best appreciated under magnification. Note a second trilobite with only the thorax preserved is present on the plate as well.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eThe host rock is slate and I like the \u003c\/span\u003e\u003cspan\u003eirregular light and dark banding. \u003c\/span\u003e\u003cspan\u003eThe patterned matrix and contrasting trilobite create an attractive miniature fossil display within a broader natural rock setting.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eThe specimen comes from \u003cstrong\u003eUpper Cambrian\u003c\/strong\u003e sediments of the \u003cstrong\u003eMcKay Group\u003c\/strong\u003e in the Bull River Valley, east of Cranbrook and Fort Steele, \u003cstrong\u003eBritish Columbia, Canada\u003c\/strong\u003e. \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003eBritish Columbia fossils are illegal to sell, except under special circumstances.
