Protobalanus spinicoronatus, (25 cm.)
Supervised by Jakob Vinther.
This fossil mollusc lived on the ocean floor about 390 million years ago. It was covered with hard plates and a ring of spikes, which constituted its defense system against predators. The strong reinforcement of the animal has made the scientists guess that it lived in an environment full of enemies.
Resembling snails, a large foot, that it used to move itself over the sea floor.
A particularly well-preserved specimen, and a CT-scanner, made it possible to construct this live-like model with all its details.
