Mode and Rate of Growth in Ammonoids
TLDR
This chapter first discusses the general mode of growth and then describes the ontogenetic sequence of growth stages in ammonoids, focusing primarily on postembryonic growth.
Mature Modifications and Dimorphism in Ammonoid Cephalopods
TLDR
The shell of an ammonoid is a kind of autobiography of the animal that once occupied it, where the growth lines and the tiny intervals in between record what was happening at the anterior end of the body.

Effect of diagenesis on the Sr, O, and C isotope composition of late Cretaceous mollusks from the Western Interior Seaway of North America
Evaluating the effects of diagenesis on the isotopic compositions of Sr, O, and C in marine carbonates is critical to their use as proxies in reconstructing information on the salinity, temperature
Ammonoid Buccal Mass and Jaw Apparatus
TLDR
Comparative anatomical examination of the attachment scars of chitin-secreting cells (beccublasts) on the jaw lamellae allow us to reconstruct the buccal mass structure of ammonoids.
The Role of Ammonites in the Mesozoic Marine Food Web Revealed by Jaw Preservation
TLDR
Three-dimensional reconstructions of the buccal apparatus in the Mesozoic ammonite Baculites are presented with the use of synchrotron x-ray microtomography to provide insights into their radiation in the Early Jurassic, as well as their extinction at the end of the Cretaceous/early Paleogene.
