Nautiloid

[EscarpmentMary]

I would like to make a entry to the collections data base and have been working on the different tags. I’m having trouble with genus and species. My geology maps say Silurian, I have narrowed it down to the Ludlum period, and believe extinction may have occurred during the Mulde event (an anoxic event) First time attempting to do this, any help at all will be appreciated.

You first need to ID the nautiloid. Post a picture so we can help you along with all the details, age, formation, locality etc. Once we have a definite ID and name then we can help determine the currently accepted name. Info in hand then it can be placed in Collections.
 

You can try Mindat for taxonomy info. Put name in search field with magnifying glass. Then search for info on GBIF and PaleobioDB websites.

Thank you I will register at mindat and carry on.

Keep in mind, the Collections area is meant to be used not only as a virtual museum, but as an aid for fossil identification. 

We want complete or close to complete, representative entries, that have all pertinent information and excellent quality photographs, that show identifying features and characteristics.

Ok no problem, whatever you say is fine with me, it was an interesting exercise. Always with greatest respect, thanks. My new rule is not to say, it’s fun, but it is lol!

• Kingdom Animalia, Phylum Mollusca, Class Cephalopoda, Order Nautiloidea, Family Lechritrocheratidae, Genus Kosouoceras, Species sand Berger’s, Suborder Barraandeocerind, Lockport Formation, Eon Paleozoic, Era Silurian, Period Ludlow, Epoch Gorstian, Barrade 1865. Location Owen Sound Ontario Canada. Observations:  Positioning of the gill indicates the left chamber is used for oxygen retrieval and ballast. The right side chamber is for retrieval of stomach nutrients. Evidence of longitudinal shell structure in the living chamber for added strength. Shell colour indicates a) camouflage and may be an adaptive feature. (Cohen 1973) Marked thickening of shell wall is perhaps also an indication of strength adaption. Durable shell structure. First shell piece indicates the shell coiled for easier mobility. Nautiloid fossil has a lamonite- stain, the shell pieces are natural. figure 1 Vojtech Turech Natinal Museum, Prague, Czech.

I really want to use the fossil forum as a public place to contribute any findings on the Niagara Escarpment.

Posting in fossil trips and member galleries will afford that very thing.

I found the paper that published these figures.  Unfortunately, the accompanying text you posted has corrupted the following terms:

Also ... a perfunctory search shows that Kosovoceras is a genus exclusively from the Czech Republic.  This info is quite a mess!

I initially said I needed help in this area, and the Czech Republic  has the best information available on the internet. In another paper by the same author, he is referring to the genus Ophioceras, which this sample does not appear to be, he refers to the stratigraphical range to include Wisconsin and Illinois. Strindberg, Turner, 1997. A revision of the Silurian Nautiloid genus Ophioceras, Barrande. I understand we are talking about a Silurian Sea, and am working to be as accurate as possible. To be honest, I wanted to give these pieces their own genus! With respect.

I have collected from tip to tip of the escarpment, and there are a number of specific papers identifying the Silurian fauna. A good place to start would be the works of T.E. Bolton, many of whose papers are freely available on Geoscan.

Thanks Kane, That is exactly the information I need. I will start tomorrow. Honestly I feel quite alone here, friends and family are encouraging but it’s hard to get information.
