Fishes
Fishes belong to the group of Vertebrates. The oldest known fish fossils are known from the lower Cambrian period. The first fishes belong to the group of jawless fishes (Agnatha). At the beginning of the Silurian period, the first jaw-fishes occurred (Chondrichthyes).
In the Devonian the first armoured fishes (Placodermi) with armoured plates at the outside appeared. Also the bone-fishes appeared. The group of bone-fishes includes most of todays fishes. Teeth, armoured plates, and vertabrea are frequently found as fossils.
