The chelicerates include the terrestrial mites, scorpions and spiders, the
marine horseshoe-crabs and the extinct sea scorpions or eurypterids, - a
of which is shown here. This specimen, is around 400 million
years old and comes from the Silurian rocks of Ringerike north of Oslo. It
was found by Professor Johan Kiær in 1909. The rectangular head shows a
variety of appendages modified for grasping, mating, walking and swimming. The long pointed tail of Mixopterus might have been curled
over the back of
the animal and used for piercing prey, such as fish, held between the
grasping appendages. The eurypterids lived from the Ordovician to the Permian
and include some of the largest known arthropods up to 2m in length.
The most famous and beautiful fossil found in Norway.
