Right click the image icon, left click open with, and select paint. You should be able to resize the image with paint.
Go to image, left click, then left click on strech/skew and decrease the size by 50% on both fields. That should make it small enough to upload. Save the image as a different file name, though.
Hope this helps.

Upload them to a hosting site like photobucket or flickr. I can never get the gallery here to take my pics no matter what I do.

How's this?

I reduced it to 800 pixels wide (and bumped the brightness & contrast a little).
Big files cause all loading problems.

Cool! The first one looks to me like a straight-shelled cephalopod; 2 & 3 may be too.

[danwoehr]

I was thinking orthocone cephalopods too.

[Ordovician_Odyssey]

any guess's for the last 2?

[Ordovician_Odyssey]

are orthacone cephalopods rare, or are the fossils i found any good?

Most definatly that was my first inklining as well.

The fossils in shale are orthoconic (straight-shelled) nautiloids that have been called Geisonoceras, but I don't know why thwy are assigned to that genus as opposed to Treptoceras, Michelnoceras, or other similar forms. They occur commonly in the Billings Shale in the Ottawa area, but sometimes they are pyritized and look great against the black shale. The trilobite Triarthus (mostly T. spinosis and T. rougensis) also occur in the same layers in the Billings shale, so you should keep an eye out for those. There is also a fairly rare coiled nautiloid, Trochlites ammonius, which you may find.

The other specimens are too out of focus to be able to say anything about them.

Triloguy,

If your camera has a macro button (flower looking icon) set that, and try to take more focused/clearer pictures of 4 and 5. To me they look like nothing right now(maybe a pyrite sun in #5) but the other things in those photos look like plain rocks. Clearer pictures might show us what you're seeing.
The cephalopods are cool.
Nice finds!

To answer your question, they are rare in some places. And yes, they are good fossils. (Aren't all fossils good? ) If you are specifically asking about the quality of preservation, you would need to take clearer pictures for us to tell!.

Thanks for sharing with us.
