Ligiidae

Ligiidae is a family of woodlice, the only family in the infraorder Diplocheta. The members of this family are common on rocky shores, in similar habitats to those inhabited by species of the bristletail Petrobius and the crab Cyclograpsus.

Time the record covers

At most 5.8 million years on record.

Every occurrence read is dated to somewhere between 106.3 Mya and 100.5 Mya, and nothing in the dating separates them, so that window is what the record shows rather than a span.

3 occurrences of Ligiidae on record, most of them in the Early Cretaceous. 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

3 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.

126 taxa

The Paleobiology Database records 1 site for Ligiidae, 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

1 reference

Each of the 3 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. Each entry links to doi.org. Relayed as the Paleobiology Database holds them, not checked against what they resolve to.
