   Bivalves appeared in Early Cambrian and were virtually cosmopolitan. In Early Ordovician the class was confined to Gondwana,their habitat was principally infaunal in the siliciclastic sediments. In the Mid Ordovician a few forms reached Baltica and Laurentia and in the Late Ordovician they become again cosmopolitan. The Silurian faunas were cosmopolitan and the major evolutionary event was caused by the appearance of a Gondwanana cephalopod limestone facies that provided sites for praecardiidinid bivalves.
