Shuko Posted February 16, 2008 Share Posted February 16, 2008 I found these two fossils in the limestone rocks that make up my house. Obviously I'll never be able to extract them from the actual rock, but I'd like to know what they are. I'm sure they're really simple IDs, but I'll be darned if I know enough to figure them out, lol. Here's the first one. Looks like it might be a kind of gastropod, but I don't know... (It's about an inch and a half long) This next one is a strange one. It looks like some kind of straight ammonoid, but since it's so broken, it's hard to tell. Any thoughts? Unfortunately, I don't know where the rocks were mined, and I don't have a better means of taking photographs. I hope this is enough to identify them!

Uncle Siphuncle Posted February 17, 2008 Share Posted February 17, 2008 Shuko Not sure about the first image, but the others are orthocone cephalopods (straight shelled nautiloids, sort of like chambered squid shells). I'm not sure of the species or even the genus, but I've heard the genera Orthoceras and Endoceras thrown around quite a bit concerning Ordovician material. Is that the age of the building material? Generally building stone is used close to where it was quarried unless a high falutin' homeowner had special material trucked in from elsewhere. Grüße, Daniel A.

Guest solius symbiosus Posted February 17, 2008 Share Posted February 17, 2008 I think you are right on the first one, and dan nailed the second. Nautiloid Cephalopods are virtually impossible to identify without a look at the siphuncle. HERE is a link to a page on Nautiloids.

PaleoRon Posted February 17, 2008 Share Posted February 17, 2008 The top fossil looks like a bisected specimen of Bucanopsis. It has a wide temporal range including Upper Ordovician and is found in North America. Link to comment Share on other sites More sharing options...
