Nice ones, hrguy, especially that last one. The coloring is beautiful!

Thanks. It showed that color in the quarry...caught my eye immediately. Was lucky to find all the pieces, just had to put it back together.

I just found this picture. :) This is the nicest cephalopod I have every found. And like "Waldo" (The enrolled trilobite I found earlier this month almost pre-prepped!) this ceph was just sitting there as is! I think if you look closely, this picture also shows the siphuncle of another ceph. The Cephalopod Gods smiled on me that day!

Ordovician, Galena Formation. SE MN.

Here's a Dumb Bev... :-D

I walked by these this morning (Brought them home sometime this spring because they sparkled.) and suddenly realized they were cephalopods! Uff dah... Because Caleb had posted his!

I love that third specimen! It's nice that part of it shows the internal

view..

A few more I pulled out of the collection drawer:

This came from the same quarry as the "orange" one from my earlier post

This one has a different look, and a nice crystallized end

Wow, your first one looks unique. It almost looks like it stopped growing, then started again..

I know horn coral have growth evidence.

I have never seen one shaped like your first one!

Usually they seem so uniform.. Very cool!

I was so curious on that first one that I have looking at a lot of images online

and still haven't found one that looks like that

Herb - what did you use to cut it?

It was cut with a thin diamond saw and polished with auto polishing compound on a flat surface.

I found this specimen at Portland Point (Middle Devonian, Moscow formation), yesterday. As is typical for the specimens I've found there, this one was crushed, lengthwise. Apparently, when this happened, one small piece in the middle got pushed out, sideways.

One side of the matrix came out intact:

The other side of the matrix broke into several pieces, along with some loose bits of the shell.

For contrast with something smaller, I also found this specimen, yesterday:

That first one is especially cool showing part of it's life. Amazing what some

creatures could go through and still live.. I don't think I have seen one do

that before. Glad you posted that! :)

Thanks, but I'm pretty sure it must have been dead by the time its shell was crushed under the sediment, Roz!

Here's a few I found in Yorkville IL.

Pic1 a nice cross section

Pic 2 and 3, I told was an Orthocone but I'm not sure.

Are those tentacles in the last pic? Could you get a closeup of that area?

It does look like it, I will take a close up when I get home later. That ladt pic was the negitive from the 2nd pic.

I am not so sure that this is a cephalopod, and I am pretty sure that those aren't tentacles.

What, I wonder, is the black material?

Oh Joey, when you take closeup pics please include the size of the fossil? :)

Could it be a fossilized root of some sort??? Just a suggestion? :)

I think it may be a type of worm. They are sometimes found in the Maquoketa and Galena Formations here in Southeast Minnesota, but well preserved ones where you can see the segments are rare. I look around and see if I can find the paper that references them, I can't even remember what they are called. I remember the original post regarding this specimen, but I couldn't seem to find it when I realized what it could be.
