Recently, my cousin returned from a trip where he acquired some bivalve fossils at a Colorado rock shop. He was told they were from Indonesia. After doing some research on the Internet of other dealers selling fossils like this, the name being used is either Paphia sp. or Striarca cheribonensis. The locality might be either Solo River or Sangrian Done, Jawa Tengah, Java, Indonesia. Fossil dates to the Pliocene Epoch.
