What is "barbatia"

Barbatia is a genus of "bearded" ark clams, marine bivalve mollusks in the family Arcidae, the ark clams.

This genus is known in the fossil record from the Jurassic period to the Quaternary period (age range: 167.7 to 0.0 million years ago). These fossils have been found all over the world.

The gens Barbatia was a Roman family during the first century BC. It may have originated with Marcus Barbatius Philippus, a runaway slave who became a friend of Caesar, and subsequently obtained the praetorship under Marcus Antonius. In 40 BC, he was quaestor propraetore under Antonius.
