Dipterus
Searched as Dipterus marginalis. The Paleobiology Database treats Dipterus as the accepted name.
Dipterus is an extinct genus of freshwater lungfish from the middle Devonian period of Europe and potentially North America. The genus was established by Adam Sedgwick & Roderick Murchison in the year 1828. It was one of the first lungfish to be described by science.

Time the record covers
At most 3.3 million years on record.
The one occurrence read is dated to somewhere between 368.5 Mya and 365.2 Mya, which is a dating window rather than a span.
1 occurrence of Dipterus 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 31 sites for Dipterus, 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.
