Trilobites, described by Stephen Jay Gould as ‘everyone’s favourite invertebrate fossil,’ are a class of marine arthropods which are often well preserved and of striking appearance.1,2They are believed to be extinct.

They are mostly between 10 and 50 mm long (3/8 to two inches) although a few species attained a length of 750 mm (2 1/2 feet). Trilobites are characterized by a ridged carapace, or shell, made of chitin, divided into three lobes which give the class its name.

While most trilobites had eyes, a number had none. A common form of trilobite eye consisted of an array of rods known as ommatidia, each of which pointed in a slightly different direction. The array was protected by a transparent membrane, or cornea. Such eyes are also found in insects and crustaceans.

However, within the family Phacopidae, there were trilobites with an eye of a fundamentally different nature, the aggregate or schizochroal eye.
