Saarolepis

Rhyncholepis was an extinct genus of anaspid from the Late Silurian. Fossils of species R. butriangula and R. parvula have been found in Ringerike, Norway, and Oesel, Estonia. The genus has two species, described in 1911 and 2002.

Time the record covers

At most 5.6 million years on record.

Every occurrence read is dated to somewhere between 428.6 Mya and 423 Mya, and nothing in the dating separates them, so that window is what the record shows rather than a span.

3 occurrences of Saarolepis on record, most of them in the Silurian. 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

3 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 3 sites for Saarolepis, 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.

Each of the 3 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.
