1.2" Onnia Trilobite - Long Occipital Spine
This is a nice 1.2" specimen of Onnia superba collected near Blekos, Morocco. The distinctive, large cephalon covered in large pits can easily be seen. It's thought that this aided in filtering food out of the water, trapping microscopic food particles in the pits. The long occipital spine has been prepared free standing, and this specimen is nicer than most.
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.
