Fossil or not

[zskgeo]

Hello,

Jsut hiking today here in Mallorca, near Andratx, and found this, looks like a bone, but I'm not sure.

What do you think?

 

 

I made a short video as well:

 

in the same area we have found some nice ammonite.. 

But the question is the stone: is it a fragment of a bone, or just a congl.?

Those ammonites.

What you have in question is low-grade chert, likely tripolitic chert.

Or a simple hardground, maybe....

I'm leaning toward tripolitic chert. All the patterns might be good for that.

I think it's a chert nodule, or maybe there are more chert nodules embedded in the sediments.

Sometimes they may look like bones, or may have strange shapes.
Take a look here:

no doubt  as Abyssunder said, zskgeo: chert
