In the bactritoids, the shell wall after hatching is composed of the principal nacreous and thin outer prismatic layers, and only the embryonic shell, or bactritella, has a prismatic ultrastructure (Doguzhaeva,

Giant Mesozoic ammonites are frequently cited examples of this trend, and the giants are typically treated as discrete taxonomic entities. In contrast, pathologic gigantism is a rare condition that results in
