Devonian Wood? Coral? Backbone?

[Chapmandale]

We went back to the Tennessee River this past weekend and found these. I would love to know what they are, or what they're not. Thanks in advance for any help with identifying them.

Here's a few more.

Last ones.

Though there are plenty of members of the fossil forum whose ID’s I’d trust more than my own here’s may take.

#4 weathered cephalopod

#2 looks woody to me but I’ve been fooled by mineral deposits in the past. Are there any leaf scares?

#1 , #6 and #8 don’t see a fossil

#3 If it’s a fossil and I had to guess I’d go with sponge

#9 and #5 horn coral

#7 septarian concretion

#1looks an awful lot like it might be a weathered stromatalite.

Rockaholic,

Thanks very much for the information. I just got through looking #2 over again, and I don't see any leaf scares.

John K.,

Thank you for your input as well.

4 is an orthocerid cephalopod, possibly Spyroceras or Dawsonoceras

9 is an internal mold of a rugose coral in chert.

3 could be a coral. Hard to tell.

2 looks like a large coral colony although a view of the top would confirm,.

Nice stuff!

#4 cephalopod

#5 gastropod

#2 stress fractures in rock, common in dolomite (dolostone)

#10 burrow

#9 horn coral

the rest appear to geologic in structure, some of a fossiliferous hash.

Looks Silurian in age to me possibly.

I don't think trees existed during the Devonian era.

Well, there was Wattieza: LINK

Thank you for the information. I had wondered if #2 might be coral as well, but I was hoping for wood. I will try to post a top and bottom view. It seems to be kind of in columns. Thanks for the link to your collection. I really enjoyed looking. Wow. Very nice. Thanks for sharing it.

Thanks so much for your input. Most of the information I've found for the area says that it is Devonian, but I've also found information that says Silurian. It's hard for me to know, but they were found in Perry County, and Decatur County on the River. I guess I can give up on my hopes for finding wood there. I have found some nice pieces of driftwood, though.
