Description
Step back over 500 million years with this authentic Elrathia sp. trilobite fossil, a beautifully preserved remnant of one of Earth’s earliest and most iconic marine arthropods. Trilobites are among the oldest known complex lifeforms, flourishing for over 270 million years across Paleozoic oceans—and Elrathia, found primarily in the USA, is one of the most recognisable genera.
This particular specimen was unearthed in Cambrian-age deposits of the western United States, and shows remarkable detail of the trilobite’s distinct body segments. With its classic three-part structure—cephalon (head), thorax (body), and pygidium (tail)—this fossil is both educational and display-worthy.

About Trilobites:
Trilobites were among the earliest known arthropods, featuring segmented bodies with exoskeletons made of calcite and chitin. Their name comes from their body being divided into three longitudinal lobes (left, middle, right), and they also have a transverse division into three main parts.
While complete specimens like this are highly sought after, many trilobite fossils are found incomplete, often with only the head or body preserved. Elrathia, particularly Elrathia kingii, is among the most studied and collected trilobites, thanks to its exceptional preservation in Cambrian shale formations.
They provide invaluable insight into early marine ecosystems, long before the age of dinosaurs or even fish.
