London, England – Trilobites dating back 508 million years have been discovered preserved in volcanic material, showcasing intricate details in 3D form. The rapid fossilization process has allowed for the preservation of tiny shells in their original position, as well as the retention of soft tissues like mouthparts and internal organs.

The trilobites were engulfed in pyroclastic flow, a dense, hot material that can spew out of volcanoes at speeds of up to 200 meters per second. While pyroclastic flow typically incinerates life in its path, the marine setting in which these trilobites were found allowed for their preservation.

Known as the “Pompeii” trilobites due to their exceptional preservation in ash, these ancient creatures were unearthed in the High Atlas of Morocco. Despite being incredibly old, these trilobites are not the oldest ever discovered, with ancient burrows like Rusophycus dating back even further at over 528 million years old.

The uniqueness of these specimens lies in the three-dimensional preservation of their appendages, offering a closer look at trilobites in a lifelike state. The detailed preservation reveals features such as a slit-like mouth and distinctive cephalic feeding appendages, providing new insights into the anatomy of these ancient creatures.

A groundbreaking study published in the journal Science highlights the significance of these findings, shedding light on the pristine preservation of these trilobites and their appendages in a 3D format. This unparalleled level of preservation allows researchers to study these ancient creatures with unprecedented clarity and detail.

The discovery of these remarkably preserved trilobites not only provides valuable insights into the past but also offers a glimpse into the fascinating world of prehistoric marine life. The meticulous preservation of these ancient creatures serves as a testament to the incredible forces of nature that have shaped our planet over millions of years.
