Hello!

 

Is this a crinoidal limestone rock?

 

Dimensions are 7 x 5 x 1 cm.

I picked it up in Braila county, Romania. A few hours ago.

 

Thanks!

Not crinoidal.

But other shells, for example bivalve or brachiopod fragments, maybe rudist fragments? Do you know an proximate age of the rock?

Sorry, no.

I picked up the stone in a freshly ploughed field (alluvial plain) some 25 km from the Danube river.
