中文摘要:The huge, up to 40-50 cm long bivalves, Lithiotis, Cochlearites and Lithioperna, which dominated within “Lithiotis” facies (sensu – Fraser et al., 2004 with lit-erature cited therein), are most significant representa-tives of buildup-maker of shallow marine/lagoonal bivalve mounds (reefs) in numerous places of Tethyan- Panthalassa margins during Pliensbachian-Early Toar-cian times. The distribution of Lithiotis-facies bivalves from Western (Spain, Italy) and Middle Europe (Slo-venia, Croatia, Albania) trough north Africa (Morocco) and Arabian Peninsula (Oman, Arabian Emirates) up to Timor Island, Himalaya Mts (Nepal, China) and west-ern margin of both Americas (USA, Peru) indicates world-wide, rapid expansion of such Lithiotis-type bivalves (Leinfelder et al., 2002; Fraser et al., 2004; Krobicki et al., 2008). The Early Jurassic migration routes were connected both with break-up of Pangea and oceanic circulation, which facilitated high speed of distribution of larva’s of such oyster-like bivalves.
