Leptoptilos robustus

Leptoptilos robustus is an extinct species of large-bodied stork belonging to the genus Leptoptilos that lived on the island of Flores in Indonesia during the Late Pleistocene. It stood at about 180 cm tall and weighed up to an estimated 16 kg (35 lb). Due to its large size, L. robustus likely occupied a terrestrial predatory or scavenging niche, likely heavily relying on the dwarfed elephant relative Stegodon florensis for a large part of its diet, and probably competing with Homo floresiensis, Komodo dragons and Trigonoceps vultures for food resources. The majority of the discoveries are concentrated in Liang Bua cave located slightly north of Ruteng in the East Nusa Tenggara province.

Time the record covers

At most 118 thousand years on record.

Every occurrence read is dated to somewhere between 129 ka and 11.7 ka, and nothing in the dating separates them, so that window is what the record shows rather than a span.

5 occurrences of Leptoptilos robustus on record, most of them in the Pleistocene. 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 occurrences

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 5 sites for Leptoptilos robustus, 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.
