Top Quality Trilobite Association (Dicranurus & Crotalocephalina)
This is an excellent, natural association of two different trilobites from the quarries at Atchana, Morocco. There is a 2.8" wide, spiny Dicranurus monstrosus association with a stunningly preserved, 3.1" long Crotalocephalina gibbus. Fantastic preparation on both specimens with the spines of the Dicranurus prepared free-standing.
The tan colored shell preservation of the Crotalocephalina makes for a nice contrast to the jet black shell on the Dicranurus. The hypostome (mouthplate) of the Crotalocephalina has been exposed on the underside of its head.

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.
