Duftonia

Searched as Duftonia morrisiana. The Paleobiology Database treats Duftonia as the accepted name.

Duftonia is a trilobite in the order Phacopida, that existed during the upper Ordovician in what is now England. It was described by Dean in 1959, and the type species is Duftonia lacunosa. The type locality was the Dufton Shale Formation, from which the generic name was derived.

Time the record covers

At most 7 million years on record.

Every occurrence read is dated to somewhere between 450.1 Mya and 443.1 Mya, and nothing in the dating separates them, so that window is what the record shows rather than a span.

4 occurrences of Duftonia on record, most of them in the Ordovician. 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

4 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 22 sites for Duftonia, and this reads all 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.

Each of the 4 occurrences 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.
