Thank you for your interest in this beautiful Sea Shell.
If you have any inquiries regarding this or any of my other listings, please feel free to contact me.

Hello and welcome! 

This is a smaller fossil sea snail, which has quite a large chunk of matrix attached to the aperture area. Some of the front and a lot of the back of the shell is revealed.

And you can see it's a well-defined ribbed pattern due to the spiral-like structure on the seashell. The shell measures about 4.5cm long, 3.5cm high, and about 3.5cm wide, making it nice and rounded and symmetrical.

What a lovely piece! Beautiful display piece for a good serious collection. With some professional skill, more of the matrix could be removed, revealing more of the fossil. 

found in the river in the Sukabumi area of West Java.
The Sukabumi area of West Java is famous among collectors for Miocene and Pliocene epoch marine deposits. River-sourced specimens like this often have smooth, water-worn outer surfaces from natural river erosion, which makes the coiling highly visible but sometimes strips away fine surface details.
This is a  a traditional calcareously replaced or siltstone-matrix cast.beautifully intact, standard matrix cast
