摘要：

The organic matrix components of a fossil ammonoid shell from the Upper Cretaceous, can be separated into sub-fractions which are generally comparable to those found in extant Nautilus, using ion exchange chromatography. This suggests that at least portions of these components are sufficiently well preserved to interact characteristically with the ion exchange resin. Amino acid compositions of these sub-fractions, however, do not resemble Nautilus organic matrix sub-fractions, indicating that considerable diagenetic alteration of this material has taken place. © 1979, Paleontological Society.
