Modiolus

Searched as Modiolus eberstadtensis intermedius. The Paleobiology Database treats Modiolus as the accepted name.

Modiolus, the horsemussels, are a genus of medium-sized marine bivalve molluscs in the family Mytilidae.

Time the record covers

At most 9.7 million years on record.

The one occurrence read is dated to somewhere between 237 Mya and 227.3 Mya, which is a dating window rather than a span.

1 occurrence of Modiolus on record, most of them in the Late Triassic. 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

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.

1,909 taxa

The Paleobiology Database records 1,572 sites for Modiolus, and this reads 240 of them. Of that, one read hit the database's own return limit, so every count below is a floor rather than a total. 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 the Paleobiology Database's own record for the work.
