Saldidae

Saldidae, also known as shore bugs, are a family of insects in the order Hemiptera. They are oval-shaped and measure 2–8 mm (0.08–0.31 in) when mature. Typically they are found near shorelines or the marginal growths near freshwater bodies, estuaries, and sea coasts. They can flee by leaping or taking flight. There are about 350 recognized species with the majority from the Nearctic and Palearctic. Many species are found in the intertidal zone and both adults and nymphs of some species like Saldula pallipes can tolerate submergence at high-tide. Saldidae are predators and scavengers. They pass the winter through egg or adult diapause.

96 occurrences of Saldidae on record, most of them in the Early Cretaceous. 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

96 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 78 sites for Saldidae, 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.

38 references

Each of the 96 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. 26 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.
