Fossilised Clam Shells with Blister Pearls

Hello,

I bought these two shells on a visit to Singapore.

I have been told that they are fossils, and they sure feel and look like it. I was told that when the supplier received them they were covered in earth.

They weigh approx 30 kg (65lbs)and measure 70cm from end to end.

I would love to know what the 'balls' are, and has anyone seen this before?

Equally is there a market for these?

kind regards

Stephane
