Skara

Skara is a genus of oligostracan pancrustaceans known from the Upper Cambrian Orsten deposit of Sweden, similarly aged deposits in China, and possibly Poland. It is the only genus in the order Skaracarida and family Skaraidae, and contains three species, S. anulata, S. minuta and S. hunanensis.

2 occurrences of Skara 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

2 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.

10 taxa

The Paleobiology Database records 2 sites for Skara, 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.

Entered from

2 references

Each of the 2 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 doi.org. Relayed as the Paleobiology Database holds them, not checked against what they resolve to.
