Welcome to TFF!

Sorry but it is not a tusk.

It may be a sponge.

Where was it found?

Welcome to the Forum. :)

 

Your item has no Schreger Lines visible/present.

Not a tusk, unfortunately. 

Looks more like a dense piece of flint or chert. 

Regards,

The texture and fracture are wrong for a quartzite like flint or chert.

So, possibly some sort of coral?

I think it's a rudist lower valve.

I suspect it being a Vaccinites species. (polished end cut)

I thank all those who responded. 

I would like to cancel that this object is completely mineralized. In fact, it's a stone.  Here are some more photos

Stones are made up of minerals.

Oh sure.  This stone scratches the glass. Obviously organic substituted silicon.

Which would make it probably chert.

Here's a petrified rudist from Upper Cretaceous of Romania, in my collection.
