| Caption: | A fossil specimen of Illaenus shallochensis Reed. A fossil trilobite. (Arthropoda, Trilobita.) Lady Burn, Drummuck, Girvan, Ayrshire, Scotland. |
| Description: | Illaneus has a strongly convex, smooth exoskeleton with large eyes. It is isopygous, i.e. its cephalon (head) is about the same size as its pygidium (tail). Its smooth exoskeleton is particularly interesting. One interpretation is that it was adapted for burrowing in the mud or bottom grazing. British Geological Survey Biostratigraphy Collection number GSE 482. Syntype. The large eyes may indicate that it lived like many current day crustaceans lying at rest they lay covered in sediment but with the eyes protruding. Trilobites are now extinct. They lived from the Cambrian to the Carboniferous periods, this specimen is from the Ordovician Drummuck Group at Lady Burn, Drummuck, Girvan. Figd. F.R.C. Reed. `L.Palaeo. Trilobites of Girvan` Mon.
