Trilobite - Fossil carapace - Metacanthina issoumourensis - Nice display

This is a finely detailed Metacanthina. Compound eyes in living arthropods such as insects are very sensitive to motion, and it is likely that they were similarly important in predator detection in trilobites. Trilobite eyes, in contrast, had rigid, crystalline lenses, and therefore no accommodation. In this specimen all the lenses are preserved. Imagine that each lens bears an individual cornea, lenses separated from each other. These eyes offered 360-degree vision to the trilobite. To think that this happened 380 million years ago seems impossible. Compound eyes are a marvel of nature. Genuine trilobite, well prepared with genal and pygidial spines. Small restoration. All these trilobites are found broken in half in the matrix and then glued back. In this specimen the glued line is less visible in person. Plate is 10 x 9 cm Trilobite is 6.5 cm long. All items are carefully wrapped and protected to reach you safely.
