Arnsbergian ammonoid biofacies in the AFB are instead dominated by
gnathodids such as Gnathodus girtyi Hass and G. bilineatus (Roundy), which are
longer ranging and of less biostrati- graphic value than the ammonoids. Key

Patterns of evolution, as illustrated by the fossil record
In this essay, I have attempted firstly to outline the major features of ammonoid

Skeletal Biomineralization: Pattern, Processes, and ...
The peculiarities of evolution of the ammonoid shell microstructure show them to

carbonate part of the shell, apparently in all adult ammonoids, consists of three
layers ...
