Description:
This is an example of the unusual trilobite Illaenus sinuatus. This
Illaenus is one of the 50-odd members of the genus, and known for
the high profile of the cephalon which is thought to have aided
the trilobite in ploughing through the substrate in search of a
meal. Typically, the large cephalon is pulled under, probably as
a result of the contraction of muscles as the trilobite died. This
one, however, is quite prone, making for a dramatic and uncommon
presentation of this unusual taxon.
