Own every card of: Trilobites.
Their body was divided into three lobes, hence the name. Trilobites filled the seas for nearly 270 million years, from the Cambrian to the end of the Permian. Their eyes made of calcite lenses are among the oldest known. Their moulting left so many shells that fossils abound.
The start of their anecdote. The album's other cards are for you to discover in the game.
Brongniart
Its head shield and tail shield form two semicircles of about equal size and without a border. The raised central area of the head runs all the way to the front edge. This trilobite swam in the Ordovician seas of northwestern Europe: Sweden, Estonia and the Saint Petersburg area. Its name comes from a Greek word meaning "indistinct".

Large mosaic eyes studded its semicircular head whose central part was pear-shaped. Its moderately vaulted body had an inverted egg-shaped outline and averaged 4 to 7 cm in length.

Workmen digging a tunnel for a dam first took it for a fossil turtle. It was a trilobite 37 cm long and 25.5 cm wide that has long been on display at the National Museum of Natural History.
