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 everyone! I may be wrong the way I was with trilobite gender, but is this soft tissue????? It might just be a stain on the rock, but it is inside a Michelinoceras body chamber, and looks similar to pictures of cephalopod soft tissue fossils (ex. the squid and octopus from Lebanon). Is this just a false alarm or am I really on to something here?

Cephalopod siphuncle preservation...a curiosity of the Hamilton group in Western New York
Al Tahan posted a topic in Member Collections
My exploration/presentation of possible (I believe probable) siphuncle preservation in Michelinoceras that I found at smokes creek in Buffalo, New York. Enjoy! In the Hamilton group found in western New York (Wanakah shale, Windom Shale) you can find 2 straight shell nautilods known as Spyroceras and Michelinoceras. Both can be found throughout the Hamilton group but there is one particular bed at the base of the Wanakah shale on top of the Ledyard shale that has a high representation of Michelinoceras. The “Mt Vernon Bed” (seen in photo) is a very hard and concretionary calcareous shale with abundant cephalopods, Gastropods and some extra fauna mixed in. You can find this bed at smokes creek and rush creek behind Penn-Dixie in Buffalo, New York The scientist in me likes to collect type (exemplary) specimens...something represantive of the species I can refer to. Once I have a great specimen I’ll only collect other “type” (exemplary) quality specimens or rare “oddities”. I recently found some rare oddities stored away that I collected of Michelinoceras a few years ago. I decided to put some study time into them cause I never really looked at them hard. After some research and observation I think I know what I’m seeing and I’m going to share my thoughts but I would love to hear from some cephalopod experts! Pic 1 : stratigraphic setting Pic 2: type (exemplary) specimen typical of Mt Vernon bed. Pic 3: 2 large supplementary type (exemplary) specimens I have. The complete specimen actually shows very faint sipluncle evidence at the bottom of the picture. Pic 4: Bombshell specimen that allowed me to link and ID the specimen in picture 5 as a Michelinoceras. Pic 5: Partial Michelinoceras showing this same oddity seen in picture 3 and 4. I am going to follow up with more up close pictures and a few words/ evidence on what I think it is.- 17 replies

On our first fossil trip (last summer) I found this cephalopod (Michelinoceras) at the Ordovician roadcut site at Antes Creek, PA. Some of those familiar with the site said they had not heard of many previous cephalopods discovered at this site and I was wondering if anyone knew if this was true.
