Lauxaniidae

The Lauxaniidae are a family of acalyptrate flies. They generally are small flies with large compound eyes that often are brightly coloured in life, sometimes with characteristic horizontal stripes, such as in Cestrotus species. Many species have variegated patterns on their wings, but in contrast they generally do not have variegated bodies, except for genera such as Cestrotus, whose camouflage mimics lichens or the texture of granitic rocks.

Time the record covers

At least 11 million years on record.

The record covers at least 48.07 Mya to 37 Mya. No occurrence read is dated outside 56 Mya to 33.9 Mya.

6 occurrences of Lauxaniidae on record, most of them in the Eocene. The Paleobiology Database records this as a living group, and the chart stops with its fossils rather than at the present. 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

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.

1,330 taxa

The Paleobiology Database records 5 sites for Lauxaniidae, 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

4 references

Each of the 6 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.
