Can anyone ID what I've found?

[Michalis]

Hello everybody,

 

I found the forum while trying to figure out how to get some info on what I believe is a fossil I found on a hike. While I'm fond of fossils,  I have to admit knowing next to nothing about them apart from what I learn from museum visits. If anyone could help me Id my find and/or estimate its age, I'd really appreciate it.

I uploaded pictures from every side with a cm scale. I found it on a river bank in the Ardennes region (Belgium).

 

Hope someone can tell me anything about it. Cheers!

While I am not very familiar with the geology of Belgium, I know a lot of that is Cretaceous similar to what we have in Texas. This looks like flint nodules in limestone, similar to what you might find here. Others may be more knowledgeable about your specific area.
