Cardium (Serripes) hamiltonensis

Not Cardium (Serripes) hamiltonensis. This is Cardium hamiltonensis Clark, 1932, a relative — both are Cardiidae.

Time the record covers
At most 16 million years on record.
Every occurrence read is dated to somewhere between 27.3 Mya and 11.63 Mya, and nothing in the dating separates them, so that window is what the record shows rather than a span.
3 occurrences of Cardium (Serripes) hamiltonensis on record, most of them in the Oligocene. The Paleobiology Database records this as a living group, and the chart stops with its fossils rather than at the present. 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
3 occurrencesThese 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 3 sites for Cardium (Serripes) hamiltonensis, and this reads all 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.

Each of the 3 occurrences read was entered from one of these publications, ordered by how many each accounts for. This is not a search for papers mentioning the name. Each entry links to doi.org. Relayed as the Paleobiology Database holds them, not checked against what they resolve to.

No 3D scan of Cardium (Serripes) hamiltonensis was found in Sketchfab.
Smithsonian Open Access and MorphoSource were not reached for this taxon, so this list is what the others held rather than everything there is.
This is what the site found, which is not the same as what exists.
