Here is a interesting trilobite of the species Ectillaenus giganteus from Portugal.
In the front of the trilobite is the rostral - plate with the partial attached hypostome well visible. A about 10 x 22 mm spot of the head is at least partial restored and the last 4 mm of the tail show a restoration as well. Anyway is this a very decorative and informative example piece of a Valongo - Trilobite.
