Abstract
MicroPIXE and STIM analysis of the chemistry of fossil and Recent polychaet e jaws (scolecodonts) demonstrates that they, apart from their protein comp osition, constitute inorganic components. The PIXE images reveal that the e lemental distribution is generally homogeneous for some elements while it i s heterogeneous, especially for zinc and iron. The jaw of the Recent polych aete Nereis sp. has zinc concentrated in the tip, probably for hardening pu rposes. Similar accumulations were revealed in fossil scolecodonts; zinc in Kettnerites (K.) martinssonii and iron and titanium in Hadoprion cervicorn is. (C) 1999 Published by Elsevier Science B.V.
