Searched as Protocardia (Protocardia) cf. goradongarensis. The Paleobiology Database treats Protocardia as the accepted name.

Protocardia is an extinct genus of saltwater clams, marine bivalve mollusks in the subfamily Protocardiinae of the family Cardiidae, the cockles.

Time the record covers

At most 3.8 million years on record.

The one occurrence read is dated to somewhere between 165.3 Mya and 161.5 Mya, which is a dating window rather than a span.

1 occurrence of Protocardia on record, most of them in the Middle Jurassic. Bar height is expected occurrences, not a count: each fossil is spread across the span it is dated to, so a tall narrow bar means tight dating and a low wide one means loose.

When

1 occurrences

These are dates about fossils, not the animal: the record can only begin after it arose and end before it died out, so either end may reach further. Shares are expected occurrences: a fossil dated to a span is counted partly in each period it straddles. More on what this infers.

The Paleobiology Database records 984 sites for Protocardia, and this reads 240 of them. The number is how many of those sites it was catalogued from too. The 24 sharing the most are listed.

This is not a list of everything alive at the time. It is only what has come out of the same ground as this animal and been written down.
