The first evidence of bioerosion in chitinous lacustrine microfossils from glacial lakes (Late Pleistocene and holocene, Bohemian forest)
Original language description
Microbioerosion structures are a common sign of microbial activity known mainly from marineenvironments and calcareous substrates, or from pollen records. However, the same phenomenon has been overlookedin animal fossils preserved in lake sediments. We studied 430 fragments of chitinous microfossils from three central European glacial lakes and detected microboring structures in approximately 10%. The microfossils belong to twosize groups: (1) spherical objects with lengths ranging from 50 to 300lm that are probably microturbelarian(Turbellaria: Rhabdocoela) cocoons, and (2) larger remnants (up to 2 mm long) of caddisfly (Insecta: Trichoptera)frontoclypeal apotomes. Four microbioerosion morphotypes were distinguished: (1) small holes (,0.6lm) orientedperpendicular to microfossil walls, likely produced by bacteria or fungi; (2) simple meandering tunnels and; (3)asterisk-like tunnel structures produced by fungi and/or fungus-like organisms; and (4) abrasions caused by biofilms.The maximum diameter of the simple holes and both tunnel structures depended on host-microfossil size: a higherdiversity of microbioerosions was found on larger chitinous fragments. We propose that the good preservation ofmicrofossils in the studied sediment samples might be due to rapid transport to the anoxic profundal zone or by rapidburial in anoxic sediments.
