worthy 55 Posted December 8, 2013 Share Posted December 8, 2013 A revisit to these fossils that were found in a North FL. river and were never ID other that they do not belong there? That was where they were found though. Any thoughts on these? It's my bone!!! Link to comment Share on other sites More sharing options...

Uncle Siphuncle Posted December 8, 2013 Share Posted December 8, 2013 looks like some cool nautiloid nodules Grüße, Daniel A. Wöhr aus Südtexas "To the motivated go the spoils." Link to comment Share on other sites More sharing options...
Al Dente Posted December 8, 2013 Share Posted December 8, 2013 I agree that the first two are nautiloids. They look like Aturia based on the indentation seen in each chamber toward the back of the fossils which would appear as a lobe if it could be seen from the side.

siteseer Posted December 9, 2013 Share Posted December 9, 2013 Worthy 55, The Florida Museum of Natural History has a number of nautiloid specimens from different Florida sites (Oligocene, Miocene, and I think even Late Eocene) in their collections but I got the impression that they are not common at any of them. Jess . Thanks for your answers I am still waiting to hear from the museum on if their are an uncommon find in Fl. Link to comment Share on other sites More sharing options...
MikeR Posted December 9, 2013 Share Posted December 9, 2013 (edited) Cool nautilus. The Florida Paleontological Society publishes a series on Florida Fossil Invertebrates through the Florida Museum of Natural History. Part 14 (Portell et. al., 2012) covers Cephalopoda. They list Aturia alabamaensis from the Upper Eocene Ocala Limestone and the Lower Oligocene Bumpnose Limestone and Aturia cf. curvilineata from the Miocene Chipola and Shoal River Formations. Those from the Suwannee Limestone which yours would surely be if collected on the Withlacoochee is identified as Aturia sp. The ones that you show are as good if not better than they picture in Plate 7 of the publication which was the first time they were reported upon in the Suwannee. Interestingly they say that the nodules from the Suwannee Limestone show radio-concentric growths of a colonial organisms such as hydrozoans. It is thought that the empty shells floated and served as a growth substrate for the hydrozoas until the shell became too heavy or beached.

Al Dente Posted December 10, 2013 Share Posted December 10, 2013 It looks like this specimen made it to the Florida Museum collections. It's good that it was donated. http://www.flmnh.ufl.edu/invertpaleo/display.asp?catalog_number=206290&gallery_type=Florida Mollusca-Cephalopoda Link to comment Share on other sites More sharing options...
MikeR Posted December 10, 2013 Share Posted December 10, 2013 So it is the same specimen. Also one of the specimens pictured in the FPS publication.

Auspex Posted December 10, 2013 Share Posted December 10, 2013 Regarding the third item: I think it is Cylindracanthus.
