Hatching size has been considered of great importance in the evolution of externally shelled cephalopods. However, our knowledge of how hatching size varies in response to biotic and abiotic factors is largely lacking. We present a comprehensive overview of hatching size in all known species of modern nautilids (225 specimens, representing eight sp...

Ammonites, as well as other fauna, were common in methane seeps of the Late Cretaceous Western Interior Seaway (WIS) of North America. Biogeochemical processes at the seeps, in particular the anaerobic oxidation of methane, produced a dissolved inorganic carbon reservoir with a low 13C, manifested in the carbon isotope composition of the inorganic...

... As a result, the DIC reservoir from which they formed reflects a mixture of methane-derived DIC and overlying water DIC. Landman et al. (2018) used the δ 13 C in well-preserved shells of seep and nonseep ammonites to estimate that the δ 13 C of the DIC in the overlying water was +2.7‰ at non-seep sites but was several permil lower, ~ −0.7‰, at seep sites. Additional sources of 13 C-enriched DIC include those linked to methanogenesis. ...
