Ammodiscus

Searched as Ammodiscus semiconstrictus regularis. The Paleobiology Database treats Ammodiscus as the accepted name.

Ammodiscus is a genus in the family Ammodiscidae of textulariid foraminifera. Ammodiscus species are vagile, epibenthic foraminiferans, usually found in seawater with normal salinity.

Time the record covers

At most 4.8 million years on record.

The one occurrence read is dated to somewhere between 303.7 Mya and 298.9 Mya, which is a dating window rather than a span.

1 occurrence of Ammodiscus on record, most of them in the Carboniferous. 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.

The Paleobiology Database records 348 sites for Ammodiscus, 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.
