  4. 3. Shell repair as a response to attempted predation in some Palaeozoic and younger gastropods

    Författare :Anna Lindström; John S. Peel; Jan Ove R. Ebbestad; Euan N. K. Clarkson; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Earth sciences; Gastropoda; predation; shell morphology; shell repair; Palaeozoic; Geovetenskap; Earth sciences; Geovetenskap;

    Sammanfattning : Traces of unsuccessful predatory attacks can be found in the hard parts of shell-bearing organisms as repaired shell injuries and are often preserved in the fossil record. These repaired shell injuries can help to deduce the relationship between predator and prey in the past. LÄS MER
