Bracteoleptaena
No picture of Bracteoleptaena was found. Wikipedia, Wikidata and iDigBio were searched and had none. Smithsonian Open Access did not answer, so this is what the others held rather than everything there is. GBIF was asked, and what came back is not recorded: nothing, or a picture this site could not tie to Bracteoleptaena, or no answer at all. This entry cannot say which.

Time the record covers
At least 12 million years on record.
The record covers at least 443.1 Mya to 430.6 Mya. No occurrence read is dated outside 449.4 Mya to 419.62 Mya.
6 occurrences of Bracteoleptaena 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
6 occurrences- Ordovician33%
- Silurian67%
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 6 sites for Bracteoleptaena, 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.
