Black and white striped fossil

[Maybecatchfire]

Greetings friends!

 

Would anyone like to weigh in on what this fossil that was found on Caspersen Beach is? A bit about where it was found, Caspersen is North of Punta Gorda and south of Sarasota. The Peace River runs into the Gulf of Mexico just a bit south of Caspersen and Englewood, and the fossils wash up on the beach from a bed near the shoreline. 
 

Any ideas on what causes the striping? I haven’t seen any like this. Apologies for all the hand photos. My lighting is meh, and it’s hard to avoid throwing shadows on the desk.

Looks like a chunck of wood?  Fossilized

I'm going to go with wood as well. However, the worn end has me curious since I don't see the typical textures I usually see in petrified wood. If you could take a clearer, more focused photo of the end, that could help a lot. The coloration can be from carbon, though there are numerous things that can factor into it.

There's a good chance this is palm wood.
