Composita

Searched as Composita dawsoni. The Paleobiology Database treats Composita as the accepted name.

Composita is an extinct brachiopod genus that lived from the Late Devonian to the Late Permian. Composita had a cosmopolitan global distribution, having lived on every continent except Antarctica. Composita had a smooth shell with a more or less distinct fold and sulcus and a round opening for the pedicle on the pedicle valve. Composita is included in the family Athyrididae and placed in the subfamily Spirigerellinae.

Time the record covers

At most 17 million years on record.

The one occurrence read is dated to somewhere between 346.7 Mya and 330.3 Mya, which is a dating window rather than a span.

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

743 taxa

The Paleobiology Database records at least 1,737 sites for Composita, 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.

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.
