Specimen size: 3.5"

Crotalocephalina gibbus is an extinct species of trilobite belonging to the order Phacopida, family Cheiruridae. It lived during the Devonian period. This species is well known from fossil deposits in Morocco.

The head or cephalon of Crotalocephalina gibbus is semicircular, with a well-defined central lobe called the glabella. This area is often enlarged and marked with prominent furrows. The trilobite also boasts large compound eyes, typical of Phacopid species, which provide an extensive range of vision. Additionally, the thorax is composed of multiple segments that are connected, allowing for flexibility and the ability to curl up for protection.

These creatures were found in the ocean, most likely on soft sea floors or near coral reefs. It is believed that they were active bottom feeders or scavengers, consuming organic matter from the sediment. Its bony outer shell may have served as protection against predators in the Devonian period, such as early fish.

Fossils of Crotalocephalina gibbus are commonly found in the Devonian formations of Morocco. Due to the well-preserved nature of these fossils, they are popular among collectors and researchers alike.
