Leptoptilos
Leptoptilos is a genus of very large tropical storks, commonly known as adjutants. The name means thin feather. Two species are resident breeders in southern Asia, and the marabou stork is found in Sub-Saharan Africa.

Time the record covers
At least 15 million years on record.
The record covers at least 15.98 Mya to 129 ka. No occurrence read is dated outside 16.9 Mya to 11.7 ka.
14 occurrences of Leptoptilos on record, most of them in the Pleistocene. The Paleobiology Database records this as a living group. 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
14 occurrences- Miocene31%
- Pliocene19%
- Pleistocene50%
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 14 sites for Leptoptilos, 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.

Each of the 14 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.
