Half the paper is potentially interesting, talking about heteromorph ammonites using their shells to incubate their eggs and then dying like argonauts do. The rest didn't fit because (at the time) the earliest argonaut fossils were much later than the latest ammonites.

Also, I've seen an old paper claiming that the three living argonaut groups have shells similar to those of different Late Cretaceous ammonite genera. The author interpreted this as evidence of polyphyletic descent of octopods from ammonites (obviously wrong), but it could also fit with the above theory.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-6903316070344664352.post-63023159377546991802007-10-10T07:22:00.000-04:002007-10-10T07:22:00.000-04:00Instead of tangents you should try secants.
