Adacna laeviuscula

Adacna laeviuscula is a brackish-water bivalve mollusc of the family Cardiidae, the cockles. It has an irregularly oval, thin, semitranslucent white shell, up to 40–50 mm (1.6–2.0 in) in length, with a narrower anterior end, and flattened ribs. The species is endemic to the Caspian Sea. It lives at depths from 0 to 30–60 m and burrows into soft sediments.

Time the record covers

At most 118 thousand years on record.

The one occurrence read is dated to somewhere between 129 ka and 11.7 ka, which is a dating window rather than a span.

1 occurrence of Adacna laeviuscula on record, most of them in the Pleistocene. The Paleobiology Database records this as a living group. 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 1 site for Adacna laeviuscula, 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.

Entered from

1 reference

Each of the 1 occurrence 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.
