Parka
Parka decipiens is a Devonian fossil believed to be an early land plant, and is the only species described in the genus Parka. It bears at least a passing resemblance to the alga Coleochaete, but the significance of this similarity is yet to be established.

Time the record covers
At most 9.7 million years on record.
Every occurrence read is dated to somewhere between 422.7 Mya and 413.02 Mya, and nothing in the dating separates them, so that window is what the record shows rather than a span.
5 occurrences of Parka 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
5 occurrencesThese 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 2 sites for Parka, 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 5 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. Entries link to doi.org where the Paleobiology Database holds an identifier, and to its own record where it does not. Relayed as the Paleobiology Database holds them, not checked against what they resolve to.
