Phragmochaeta canicularis

Phragmochaeta canicularis is an extinct animal belonging to the annelids and lived in the Early Cambrian. Fossils have only been found in the Buen Formation at the Sirius Passet Lagerstätte, Greenland and the animal is probably the first polychaete.

Time the record covers

At most 5 million years on record.

The one occurrence read is dated to somewhere between 521 Mya and 516 Mya, which is a dating window rather than a span.

1 occurrence of Phragmochaeta canicularis on record, most of them in the Cambrian. 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.
