Asaphiscus wheeleri Trilobite

Travel back approximately 507 million years to the Middle Cambrian Period with this impressive Asaphiscus wheeleri trilobite fossil from the famous Wheeler Shale of Millard County, Utah. This beautifully detailed specimen offers a fascinating glimpse into the ancient marine ecosystems that existed long before dinosaurs roamed the Earth.

Measuring approximately 3 inches, this trilobite features a broad, rounded head with a prominent central glabella, numerous sharply defined thoracic segments, and a large, fan-shaped tail section known as the pygidium. The raised central axis and finely preserved segmentation create an intricate three-dimensional appearance, highlighting the remarkable anatomy of this prehistoric marine arthropod.

The fossil is prominently displayed on an approximately 4.25 x 4-inch dark gray shale matrix with a relatively flat, trimmed surface and slightly irregular edges. Its well-defined exoskeleton stands out against the surrounding stone, making the specimen an attractive display piece from multiple viewing angles.

Asaphiscus wheeleri is a distinctive Cambrian trilobite recognized for its broad body and unusually large pygidium. Trilobites were among the earliest successful groups of marine arthropods, inhabiting Earth's oceans for hundreds of millions of years. Their segmented exoskeletons provided protection while allowing flexibility and movement along the ancient seafloor.

The Wheeler Shale is one of North America's most celebrated Cambrian fossil deposits, renowned for preserving an extraordinary diversity of early marine life. Fossils from this formation provide valuable insight into the evolution of complex animal life during the Cambrian Period.

With its impressive size, detailed preservation, and classic Wheeler Shale matrix, this Asaphiscus wheeleri trilobite makes an excellent addition to any fossil collection or natural history display.
