Polychaeta életnyomok vizsgálata egerien magános korallokon (Wind-féle téglagyár, Eger). [(Traces of Bioerosion of Polychaete Worms on the Tests of Egerian Age Solitary Corals /Wind Brickyard, Eger, Hungary/)]

(Traces of Bioerosion of Polychaete Worms on the Tests of Egerian Age Solitary Corals /Wind Brickyard, Eger, Hungary/) 1108 solitary coral specimens were collected from the glauconitic sandstone layer of the Wind Brickyard’s exposure by the author. Traces of the activity of Polychaete worms have been observed on the tests of 493 specimens of seven species. These belong into the following ichnospecies: Caulostrepsis taeniola Clarke, 1908; C. biforans (Gripp, 1967); C. cretacea (Voigt, 1971); Maeandropolydora decipiens Voigt, 1965; M. sulcans Voigt, 1965; M. elegans Bromley-D’alessandro, 1983; Trypanites solitarius (Hagenow); és a T. weisei Mägdefrau 1932. Odontocyathus armatus (Michelotti 1838) tests contain most of the traces. While the most significant ichnospecies is the Maeandropolydora sulcans. The most preferred position for the settlement of the larvae was the upper third part of the corallite. According to the frequency and the position of the traces we can conclude on shallow marine, environment with considerable currents. It is also shown by the position of the traces that the corals lived when the annelid larvae settled on them.
