These early nautiloids had conical shaped shells. In the Silurian some nautiloids used curved shells, and by the Devonian some were coiled. The evolution of the coiled shell from the straight is thought to be driven, at least in part, by increased mobility of a coiled shell compared to a long straight one.</p> <p>Nautiloids could be confused with ammonoids. You can distinguish them by the location of the siphuncle and the complexity of the suture pattern. Nautiloids, unlike ammonoids, are not extinct, although only six species remain today (compared to thousands in the Palaeozoic). This means that if presented with modern shell material it is likely a nautiloid and not an ammonoid.</p> <h2>Specimens</h2> <p><a href="/p1acollections/exhibits/show/nautiloids">Browse nautiloids</a></p> <h2>External links</h2> <p><a href="https://www.youtube.com/watch?v=2ilSDcZAXNM" target="_blank" rel="noreferrer noopener">Telling planispiral fossils apart</a></p> nektonic https://wserv3.esc.cam.ac.uk/p1acollections/files/original/a2dca59737eb2c3d29333e3962ec3b2c.png 3ba4d8fd1792ea4b1f901fd6231abc77 https://wserv3.esc.cam.ac.uk/p1acollections/files/original/ce333ef152dcc34b5bb15d92b0d8a85e.png b659a0b06a3b027e8a5add24e3407d70 Dublin Core The Dublin Core metadata element set is common to all Omeka records, including items, files, and collections.
