Waeringopterus
Waeringopterus is a genus of prehistoric eurypterids from the Silurian of North America. The genus contains two species, W. apfeli from the Syracuse and Vernon Formations of New York and Ontario and W. cumberlandicus from the Wills Creek Formation, West Virginia. Fossils of the genus also were found in the Indian Point Formation of Quebec.

Time the record covers
At most 24 million years on record.
Every occurrence read is dated to somewhere between 443.1 Mya and 419.62 Mya, and nothing in the dating separates them, so that window is what the record shows rather than a span.
7 occurrences of Waeringopterus 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
7 occurrences- Silurian100%
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 7 sites for Waeringopterus, 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.
