New Identification Posters for Common Hamilton Group Cephalopods
Bringing Fossils to Life posted a topic in General Fossil Discussion
I just made new ID posters for Hamilton Group Cephaloods - one for Nautiloids and Bactritoids, and one for ammonoids. The reconstructions are either new or updated for accuracy. Color patterns on the first picture are based on close relatives. If anyone has any suggestions, please let me know - I want these to be as useful as possible.- 6 replies

Hi we've found these fossils in buffalo ny and based only on google searches we see resemblance with eurepterids as well as straight shelled nautiloids. Any help would be greatly appreciated. The photos shown are all different fossils I have them labeled a through c to make identification discussions easier. Thankyou in advance, we're learning!

Today I took my two youngest to Cole Hill Road, for a Dipleura hunt. We got there shortly after 10 am. Right off the bat my son Devin found two rather nice bivalves that I had left behind from my last trip. I forgot about them and let him keep them. I decided to work the same spot and see how things went. Bembexia was the flavor off the day. I found so many of them. I only kept the ones that popped out of the matrix. I found a few Spyroceras that were bigger then what I normally find at this site. A few other goodies that I haven't I'd yet. I really had a hard time keeping the boys focused today. I know that they are getting bored with this type of hunting. They really want to do some sharktooth hunting. So I tried to hype things up with telling them I had good feeling about finding a large Dipleura. I did have a good feeling but I only half believed it. I decided to dig where I found a nearly complete one last summer. Under some plants and shrubs there is highly fractured and weathered rock. I took a garden hoe and started yanking out all the loose rock. After a couple minutes I see a rock with segments start rolling down the debris pile I was making. Immediately I knew what is was. Only I didn't know how much was there or the condition. It is not the biggest I ever found. Nor is it in great condition. But I can't complain considering I worked the weathered section of the cliff. Pygidium , thorax, and cephalon are all present but with some damage. All in all it was a great day to be out with my boys and finding some decent things. I am posting a few photos now and I will post more after I clean things up. Hope you enjoy.

Spyroceras Cephalopod in Matrix Chesterian Zone of the Bangor Limestone Formation in northern Alabama Mississippian Period (ca 325,000,000 years old) Spyroceras is a genus of pseudorthocerids from the Devonian of North America and Europe, defined by Hyatt in 1884. Pseudorthocerids are a kind of orthocertaoid, a taxonomic group within the Nautiloidea. Spyroceras had annulated orthocones with straight transverse sutures, transverse or slightly oblique surface annulations, and faintly cyrtoconic apeces Surface ornamentation varies but longitudinal lirae are conspicuous from earliest stage. The siphuncle was central or slightly offset ventrally, and composed of expanded segments typical of the Pseudorthocerida. Cameral and siphonal deposits developed later than in most pseudorthocerids and are thus confined to the apical portion of the phragmocone. Kingdom: Animalia Phylum: Mollusca Class: Cephalopoda Order: Pseudorthocerida Family: Spyroceratidae Genus: Spyroceras-

Found some amazing stuff today with @Kane @ischua @DevonianDigger @Fossildude19 and @drobare We hauled some serious rock and had somewhat of an assembly line going with splitting and processing the pieces. It was a really solid day all around and everyone walked away with some sweet finds. The following is a sample of some of the cool stuff I've found. The rest is packed away. The first is a large cephalon and will look good despite not having a body and then there's a Spyroceras cephalopod that might benefit from some very gentle prep work. I really like cephalopods because of all the neat chambers they contain.

Hey guys, found my first Spyroceras (i think) at the Penn Dixie site a few weeks ago, cleaned her up, and applied some glue/water mix to make her stand out. The thing is though, I'm not sure if the space down the center of the fossil is separating the two halves of the fossil or if I have two parallel fossils. So, I didn't apply glue to that area because I wasn't sure if it was actually part of the fossil(s). This is all I found, I didn't find a top half sorry. Hope the pictures are ok. Any help is appreciated, let me know if I can do anything. Thanks in advance!!

Here are some images of spyroceras nuntium (a Devonian cephalopod) from our Tully NY trip. The internal cast plus fragments of the outer shell are visible. My wife has asked if someone might be able to shed some light on the "smoothe" tube structure - is this possibly the outer coat of a spyroceras or other cephalopod? (see Unidentified 1 and 2 below). Thx.
