Dorfopterus
Dorfopterus is a genus of extinct invertebrate, possibly an eurypterid. Only one fossil of the single and type species, D. angusticollis, has been discovered in deposits of the Early Devonian period in the Beartooth Butte Formation in Wyoming, in the United States. The first half of the name of the genus honors the discoverer of this formation, Erling Dorf, while the second half consists in the Ancient Greek word πτερόν (pteron), meaning "wing". The species name angusticollis is composed of the Latin words angustus ("narrow") and collum ("neck").

Time the record covers
At most 18 million years on record.
The one occurrence read is dated to somewhere between 410.62 Mya and 393.47 Mya, which is a dating window rather than a span.
1 occurrence of Dorfopterus on record, most of them in the Devonian. 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- Devonian100%
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 1 site for Dorfopterus, 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.
