Ia

Ia is a genus of bat in the family Vespertilionidae. It belongs to the subfamily Vespertilioninae and has been placed in the tribe Vespertilionini. In the past, it has also been considered a synonym or subgenus of the genera Pipistrellus or Eptesicus, which used to contain many more species than they do now. Ia comprises a single living species, the great evening bat (I. io) of eastern and southeastern Asia, and one extinct fossil species, I. lanna, from the Miocene epoch in Thailand. Another living species, I. longimana, was recognized in the past, but it is no longer considered a valid species distinct from the great evening bat.

2 occurrences of Ia on record, most of them in the Miocene. 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

2 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.

Found in the same rock

120 taxa

The Paleobiology Database records 2 sites for Ia, 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.

Entered from

2 references

Each of the 2 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.
