Ruger9a Posted March 31, 2020 Share Posted March 31, 2020 Interesting item. Don't know if it's a fossil though. Where did it come from? Link to comment Share on other sites More sharing options...
Drawson Posted March 31, 2020 Author Share Posted March 31, 2020 I found it in on a beach in Kenai, Alaska. It weighs 24 lbs and up-close you can see the grain of the wood. Link to comment Share on other sites More sharing options...
JohnJ Posted March 31, 2020 Share Posted March 31, 2020 Many rocks can appear to have a "grain" similar to wood, and not be fossil wood. Do you have other close up photos? @ynot 1 The human mind has the ability to believe anything is true. - JJ Link to comment Share on other sites More sharing options...

Drawson Posted March 31, 2020 Author Share Posted March 31, 2020 thank you for your response! I do not know much about geology, but i'm trying to figure out what this is, and any help is much appreciated! The best I could come up with is petrified wood. 1 Link to comment Share on other sites More sharing options...
JohnJ Posted March 31, 2020 Share Posted March 31, 2020 It looks like a metamorphic or igneous rock. 2 The human mind has the ability to believe anything is true. - JJ Link to comment Share on other sites More sharing options...
Rockwood Posted March 31, 2020 Share Posted March 31, 2020 Agreed. It is close to what a burl would look like. I would expect to be able to identify a bit more connectivity in the grain though. Burl is living wood that still needs to function as such. 1 Link to comment Share on other sites More sharing options...

All this glossy black stuff isn´t very typical for metamorphic or igneous rocks. However, it reminds me somewhat of obsidian or pitchstone. @Drawson, have you polished this specimen? You can also make a test: Pry of a small splinter of the glossy, black stuff and hold it into a flame (lighter, candle, gas cocker). What happens? But be careful, please wear goggles.

Especially if it reminds you of obsidian (which is an igneous rock) or pitchstone which is discussed to be devitrificated obsidian....

Franz Bernhard Your statement " All this glossy black stuff isn´t very typical for metamorphic or igneous rocks" with a link to the statement of JohnJ, Rockwood and me in which we stated that it is likely igneous rock has been understood in the way that you do not think it is igneous rock and even it is not typical for it. But in contrary volcanic glasses are common igneous rocks and not unusual. So yes, maybe just a confusing statement.... Never mind.... Link to comment Share on other sites More sharing options...

supertramp Posted March 31, 2020 Share Posted March 31, 2020 Looks like a migmatitic rock https://www.google.com/search?q=migmatitic+rock&tbm=isch&ved=2ahUKEwjd65m6pMXoAhUJQBoKHX9MB3IQ2-cCegQIABAA&oq=migmatitic+rock&gs_lcp=CgNpbWcQAzoCCAA6BAgAEEM6BAgAEB46BAgAEBNQjK4IWOThCGCW5QhoAHAAeACAAZYBiAGPDJIBAzcuOJgBAKABAaoBC2d3cy13aXotaW1nsAEA&sclient=img&ei=J4SDXp28KYmAaf-YnZAH&bih=625&biw=1366&hl=it ciao Link to comment Share on other sites More sharing options...
Rockwood Posted March 31, 2020 Share Posted March 31, 2020 The close up view could pass for wood. I still think the overall configuration of the layers is too concentric in nature to be wood though. I think the growth layers need to be functional like a normal tree trunk would be, albeit distorted. In hand it may be easier to make out a workable pattern I suppose.

ynot Posted April 1, 2020 Share Posted April 1, 2020 I do not see wood, I see a metamorphic rock that had a lot of stress during its creation. 1 Darwin said: " Man sprang from monkeys."
