Pair Of Large Lower Cambrian Trilobites (Longianda) - Issafen, Morocco
This is a spectacular double Longianda termieri specimen from Issafen, Morocco. This piece had been in my personal trilobite collection until recently.
Both trilobites are quite large and 5.6" and 4.8" long and well prepared to bring them out in high relief against the rock. They have a layer of rust-red limonite around their borders which is typical of many trilobites from this locality. The stone has mostly been removed around one specimen leaving it flying on a pedestal in a spectacular display. This trilobite also has some pyrite cubes embedded in its head, lending to the uniqueness of the piece.

In the past few years, deposits near Issafen, Morocco have begun yielding a new assemblage of Early Cambrian trilobites. This fauna is very diverse and consists mainly of ellipsocephalids, chengkouiids, gigantopygids, holmiids, neltneriids, saukiandids, and the latest fallotaspids. The shale is a greenish to slightly yellow color when freshly split, but weathers to a light grey.
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.
