✅ SOLVED Petrified burnt wood?

[No Quarter]

Found this about 8" in sand at a local saltwater beach. Kinda heavy for its size. Couple flakes that came off are sharp as glass.

Yeah but its not crumbly like coal. Doesn't leave any mark on hands or paper. And doesn't break easily. Feels like a stone. I pried couple flakes off and they were sharp like shards of glass.

Its difficult to see in the pics I took but it has wood-like grain that runs length of it, but probably is anthracite coal afterall. Btw can you recommend any books or other resources on coal identification? Thanks again for your help guys!

There are many types of coal, some are hard, some soft. Coal can form in various formations, I have a lot of coal in my backyard from when there was my house took coal, and some of it looks like that, it usually is very flaky too. Also, Last time I was at a beach I found coal just like that, strange coincidence.

Here is what petrified wood looks like:

It seems like you really did get coal for Christmas lol!
