Alydidae

Alydidae, commonly known as broad-headed bugs, is a family of true bugs very similar to the closely related Coreidae. There are at least 60 genera and 300 species altogether. Distributed in the temperate and warmer regions of the Earth, most are tropical and subtropical animals; for example Europe has a mere 10 species, and only 2 of these occur outside the Mediterranean region.

20 occurrences of Alydidae on record, most of them in the Oligocene. 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

20 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.

1,123 taxa

The Paleobiology Database records 13 sites for Alydidae, 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

10 references

Each of the 20 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.
