Abstract

X-ray diffraction and infrared absorption spectra show that the spicules of the common tropical ascidian, Herdmania momus, are mineralized with vaterite. These are the first strictly marine organisms known to normally precipitate vaterite. The biomineralization of vaterite may constitute another link between the urochordates and vertebrates. The vaterite of ascidian spicules immersed in natural seawater remains mineralogically unchanged for 1 year, which indicates that vaterite may be preserved transiently in marine sediments.

Rossman for helpful comments on the manuscript, P. K. Mather and E. C. Pope for the Australian and Tasmanian H. momus samples, and J. E. Fitch for the fish otoliths. K. M. Towe and J. E. Fitch called our attention to some pertinent literature references. M. Dekkers skillfully prepared the samples. A. A. Chodos performed the electron microprobe analyses, B. Bingham the x-ray diffraction analyses, and S. Weiner the infrared absorption spectra. K. Evans and S. Weiner obtained the scanning electron micrographs. Supported by NSF grant GA 36824X1.
