Schizophora
The Schizophora are a section of true flies containing 78 families, which are collectively referred to as muscoids, although technically the term "muscoid" should be limited to flies in the superfamily Muscoidea; this is an example of informal, historical usage persisting in the vernacular. The section is divided into two subsections, the Acalyptratae and Calyptratae, which are commonly referred to as acalyptrate muscoids and calyptrate muscoids, respectively.

Time the record covers
At least 387 million years on record.
The record covers at least 387.95 Mya to 11.7 ka. No occurrence read is dated outside 390.5 Mya to 0 Mya.
396 occurrences of Schizophora on record, most of them in the Eocene. 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
396 occurrences- Devonianunder 1%
- Early Cretaceousunder 1%
- Late Cretaceousunder 1%
- Eocene59%
- Oligocene7%
- Miocene21%
- Pliocene1%
- Pleistocene4%
- Holocene7%
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 140 sites for Schizophora, and this reads all of them. Of that, one read hit the database's own return limit, so every count below is a floor rather than a total. 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 396 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. 128 further references are not listed. 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.
