Carolowilhelmina geognostica
Carolowilhelmina geognostica is an extinct arthrodire placoderm fish that lived in the Late Eifelian epoch of Aragon, Spain. In life, C. geognostica was a long-snouted pelagic fish, superficially similar to the Australian Rolfosteus and the European Oxyosteus. It is currently known only from an incomplete cranium that is about 43 cm (17 in) long. The fossil material is housed in the Natural Sciences museum of the University of Zaragoza, Spain.

Time the record covers
At most 5.6 million years on record.
The one occurrence read is dated to somewhere between 393.47 Mya and 387.95 Mya, which is a dating window rather than a span.
1 occurrence of Carolowilhelmina geognostica 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 Carolowilhelmina geognostica, 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.
