PaleoNet: Mineralogy of fossil remains

[Thomas, Ellen]

I noted ’vaterite’ next to Octocorallia. At least some foraminifera have vaterite as a phase during test formation:
Jacob et al., 2017, Planktic foraminifera form their shells via metastable carbonate phases, Nature Comm 8, 1265.

Dear PaleoNetters,

here attached are the new version of the table to compare with its 60 years old original version.

Special thanks go to Phil Bock, David Campbell, David A.T. Harper, Roy E. Plotnick, and Thomas E. Yancey, who kindly provided some missing information.

Should you think of any further improvements, please do not hesitate to let me know.

=) Bruno Granier

Dear PaleoNetters,

I have a special enquiry (please respond to me directly, not to the whole PaleoNet members ... I should provide a table at the end):

Can you help me sorting out the mineralogy (aragonite, calcite, both of them) of some fossil groups?

For instance, to my knowledge, most (all?) Bryozoan remains are calcitic (when mineralized). Do you know aragonitic ones (please provide a bibliographic reference supporting such evidence)?

For instance, to my knowledge, most (all?) Gastropoda remains are aragonitic (when mineralized). Do you know calcitic ones (please provide a bibliographic reference supporting such evidence)?

For instance, to my knowledge, most (all?) Cephalopod remains are aragonitic (when mineralized). Do you know calcitic ones (please provide a bibliographic reference supporting such evidence)? In this case it could be both because Aptychi and Rhyncholites are calcitic.

Same question for Porifera, Hydrozoa, Octocorallia, Zoantharia, Stromatoporoidea, Brachiopoda, and Arthropoda.

Thanks in advance for your appreciated help.

Bruno Granier
