Co-evolution has been invoked as an explanation for Lake Tanganyika’s unusual endemic fauna. The crabs Platytelphusa armata and Potamonautes platynotus are molluscivores, found in the same habitats as the gastropods Lavigeria coronata, L. grandis, and L. nassa (West & Cohen 1994). As these are the largest gastropods in the Lavigeria species flock, and often the most exposed, we are determining ...

—A global database of gastropod sizes from the Permian through the Middle Triassic documents trends in gastropod shell size and permits tests of the suggestion that Early Triassic gastropods were everywhere unusually small. Analysis of the database shows that no specimens of unambiguous Early Triassic age larger than 2.6 cm have been reported, in contrast to common 5– 10-cm specimens of both Pe...

Tong, Jinnan, and Douglas H. Erwin. Triassic Gastropods of the Southern Qinling Mountains, China. Smithsonian Contributions to Paleobiology, number 92,47 pages, 11 figures, 6 plates, 5 tables, 2001. Forty-eight species in 27 genera of gastropods, including 14 new species and one new genus, are described from earlyto middle-Triassic (Scythianto Ladinian-aged) rocks from the southern Qinling Moun...

This article studies the indicator properties of gastropods common in Upper Syr Darya River basin. They are divided into ecological groups according to their habitats. The generally accepted and zoological methods were used research. According research results, fresh-water Fergana Valley inhabit xenosaprobic, oligosaprobic, β – mesosaprobic, α mesosaprobic polysaprobic waters. Molluscs mainly d...
