Sabellaria

Sabellaria is a genus of marine polychaete worms in the family Sabellariidae. The type species is Sabellaria alveolata. These worms are sedentary and build tubes in which to live from sand and shell fragments. Some species are called honeycomb worms and when they occur in great numbers they can form reefs on rocks and other hard substrates. They are filter feeders, extending a plume-like fan of radioles from the end of the tube in order to catch plankton and detritus floating past. They have a distinctive operculum which is used to block the opening of the tube when the radioles are retracted.

Time the record covers

At most 6.9 million years on record.

The one occurrence read is dated to somewhere between 132.6 Mya and 125.77 Mya, which is a dating window rather than a span.

1 occurrence of Sabellaria on record, most of them in the Early Cretaceous. 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 1 site for Sabellaria, and this reads all of them. The number is how many of those sites it was catalogued from too.

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 the Paleobiology Database's own record for the work.
