If you know where it’s from you might be able to infer the age and then narrow down your field. I’m not well versed in dino bones but I don’t see any features that would be diagnostic. Someone else might. If you take a thin section you might be able to show it to someone who works with bone microstructure.

If you don’t have the ability to take a thin section then don’t worry about it too much. It can sometimes be more trouble than it’s worth. It’s also cool to just have a large chunk of a mystery dinosaur!

Thanks you!
