I'll keep my fingers crossed for you D!

Finger, eyes, toes - anything sending good vibes is most appreciated.

Hey Kevin, I have a slight dellima, I have several different locations in this thread and I have more fossils (that I want to post) from the site where I found the sponge. So I'm wondering if I should start a thread for that location and if so could the posts from that location be moved to the thread, the posts are 17-30 and 46-50.
OR do I keep putting everything here and specify the different location (Bigby-Cannon Limestone). I just thought maybe it would be less confusing to have them all together, Oh yes and the sponge

I should start a thread for that location and if so could the posts from that location be moved to the thread, the posts are 17-30 and 46-50.

Sure, we can move some posts that's not a problem. It might be good to start another thread that way it is easier for others to search through your findings and discussions in the future.

Thanks Dave, I thought I would use "Bigby-Cannon Limestone" as a title.

Terri, let me know if I have moved the right posts.

**Terri** · Apr 24, '11, 9:51pm

Yes, thanks Kevin, I think that's all of them!

I'm so glad I went back to this location looking for the ever elusive sponge, here are a few fossils I found while looking. The first one I'm excited about, would this be original shell material? I'm not used to finding this type of preservation. Most of it has some type of (?reef or algal stuff) covering it.

**Terri** · Apr 26, '11, 12:07am

..and possibly an Endoceras? About 6cm. long.

This one's soaking right now, I think I can get a view of the siphuncle,about 4 cm. long. There are quite a few of these scattered around on the rocks, but really weathered and broken and have that same golden, brownish color.

Very nice fossil. It sure looks like the outer shell, and the septa showing on the other end help that look. Is the end view broken on one of the septa? Is it a convex surface with the siphuncle in the center?

I can't see any sign of the siphuncle or endocones to verify, maybe just a very nicely preserved Orthocerid.

Some nice fossils, keep looking for that sponge and find more of these

I'm not sure if it's broken on the septa, I don't know what to look for, doesn't seem to be, I'll try to get a better shot of both broken ends tommorrow.

It is convex, looks kind of flat in the pic. and the siphuncle is just about perfectly centered.

**Terri** · Apr 26, '11, 1:31am

I'm looking at another pic. and if I'm understanding your question it looks like it's broken right on or just barely before the septa, I'll post the pic. it might take a minute my connection is really slooww tonight.

**Terri** · Apr 26, '11, 1:51am

Ok here it is, totally lost my connection the first time.

That last photo looks like one of Hajars, with the septa showing through the shell, makes it look like a residual color pattern.

On the other piece, is it concave?

Very nice to see Ordovician fossils preserved this good.

Yes it does, doesn't it! But do you think it IS a residual color pattern or does it just appear to be?

If I could just get photos as good as his!

On the other piece, is it concave?

Convex also. I took more pics. today, have to upload and go through them, hopefully I got a few that shows more detail. The break is so clean, I'm really dissapointed in the pic. of the end I posted yesterday, just looks like a blurry blob.

**Terri** · Apr 26, '11, 11:07pm

Here's the siphuncle looking towards the apertural end..

**Terri** · Apr 26, '11, 11:18pm

...and looking towards the apex

**Architeuthoceras** · Apr 27, '11, 12:52am

Looks like it broke between septa. I can't tell if that is just crystals filling the chambers or if it is some kind of cameral deposits, I can't see a good surface for the septal necks or connecting tube, very nice at any rate.

Do you know what all the little honeycomb things are? Some kind of Coral?
