minnbuckeye Posted June 18, 2020 Share Posted June 18, 2020 Look up Graf, Iowa. A 15 minute visit will provide you with a bucket full of Isorthoceras sociale. Locally in SE Minnesota, other Orthceras are fairly common. Why the question? Are you looking for specimens? Mike 1 Link to comment Share on other sites More sharing options...

connorp Posted June 18, 2020 Share Posted June 18, 2020 I thought that Orthoceras was cleaned up recently? From Wikipedia: ”Orthoceras was formerly thought to have had a worldwide distribution due to the genus' use as a wastebasket taxon for numerous species of conical-shelled nautiloids throughout the Paleozoic and Triassic. Now, Orthoceras sensu stricto refers to O. regulare, of Ordovician-aged Baltic Sea limestones of Sweden and neighboring areas.” 3 Link to comment Share on other sites More sharing options...
Miocene_Mason Posted June 18, 2020 Share Posted June 18, 2020 While Orthoconic nautilus can be found in various places throughout the United States, Orthoceras itself is indeed limited to Scandinavia at the moment. 1 “...whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been and are being evolved.” ~ Charles Darwin Happy hunting, Mason Link to comment Share on other sites More sharing options...

Mike thank you, I will look up graf, Iowa. I’ll check those places out at some point, but I probably won’t be able to get to Minnesota or Iowa till next year at least. I was just wondering because I thought it would be cool to find a couple. 3 hours ago, DPS Ammonite said: I forgot to mention to use the search function on the Forum to find info. http://www.thefossilforum.com/index.php?/topic/83526-the-upper-ordovician-nautiloid-beds-of-graf-iowa/ You also can can let Google search the Forum for you.

I’m fine with conical shelled nautiloids. Link to comment Share on other sites More sharing options...
FossilDAWG Posted June 18, 2020 Share Posted June 18, 2020 If you capitalize Orthoceras, that suggests you are talking about the particular genus, which as @WhodamanHD and @connorp have pointed out is now restricted to some species that occur in the Baltic area. At one time "Orthoceras" was used for all straight-shelled nautiloids, which have in the last 100+ years been recognized to contain hundreds of different genera and thousands of species. If you want to refer to just any straight-shelled nautiloid, you can call them orthocerids or orthoconic nautiloids (without capitalization). It seems a bit picky perhaps, but being precise in naming things is essential in science. Otherwise we don't really know what it is that someone is talking about (or asking about). Note that the genus name is always capitalized, the specific name is not, and both are either underlined or italicized. For example: Orthoceras regulare is correct.

FossilDAWG Posted June 18, 2020 Share Posted June 18, 2020 Nothing to be sorry about. Just a "teachable moment" for the whole community. This is a science-based forum, so when the opportunity to educate presents itself, it seems like the thing to do. The "orthoceras" issue comes up a lot.

Jeffrey P Posted June 20, 2020 Share Posted June 20, 2020 Straight-shelled nautiloids are prolific in abundance in marine Paleozoic rocks. I've seen many fine examples at sites in the Hudson Valley and Central New York, and at sites in the Ohio Valley. Some of the best ones I've seen on the Forum came from the Toronto area. The NY Paleontological Society has outings planned to sites in Upstate New York where nautiloids can be found as well as lots of other things. Good luck! 3 Link to comment Share on other sites More sharing options...
FossilNerd Posted June 21, 2020 Share Posted June 21, 2020 I agree with Jeffrey P. If you are referring to any orthoconic nautiloid, many species can be found all over U.S. in Paleozoic age rocks. They may not be in the once catch all Orthoceras genus anymore, but that doesn’t mean they don’t resemble them in a general sense. 1 The good thing about science is that it's true whether or not you believe in it. -Neil deGrasse Tyson Everyone you will ever meet knows something you don't. -Bill Nye (The Science Guy) Link to comment Share on other sites More sharing options...
