7.4" Asaphid Trilobite in Concretion - Pos/Neg
This is a large, 7.4" long Asaphid trilobite in a sandstone concretion from the Kataoua Formation of Morocco. It has a beautiful orange coloration, is very inflated and both halves of the concretion are included. This is one of the nicer examples of these large Asaphids I've seen. The orange coloration is completely natural, caused by the oxidization of iron pyrite which originally replaced the trilobite. There are a few repaired cracks on both halves, but no restoration.
About Trilobites
Trilobites are an extinct class of marine arthropods that thrived for nearly 270 million years, from the early Cambrian to the end of the Permian period (around 521 to 252 million years ago). They are one of the most successful and diverse groups in the history of life, with over 25,000 described species spanning a wide range of sizes, shapes, and ecological niches. Known for their distinctive, segmented exoskeletons, trilobites provide invaluable insights into the evolutionary history of arthropods and the dynamics of ancient marine ecosystems.
