Andalusiana Paradoxides Trilobite from Morocco (694.7 grams)
Paradoxides is a genus of large to very large trilobites found throughout the world during the Mid Cambrian period.It has a semicircular head, free cheeks each ending with a long, narrow, recurved spine, and sickle-shaped eyes, providing almost 360° view, but only in the horizontal plane. Its elongated trunk was composed of 19-21 segments and was adorned with longish, recurved lateral spines. The exoskeleton of Paradoxides is large to very large, relatively flat, oval to inverted egg-shaped, and about one and a half times longer than wide, with the greatest width across the genal spines.
Trilobite refers to an extinct class of arthropods. Tri-lobe0ite alludes to the three-part, longitudinal division of their exoskeleton. These animals first appeared at the beginning of the Cambrian Period around 570 million years ago. They flourished throughout the early Paleozoic Era and then decreased in diversity until their extinction in the late Permian Period around 240 million years ago. These marine invertebrates were primarily bottom dwellers. Fossilized remains of trilobites have been found on every continent and admired by humankind, considered objects of value for thousands of years.
