Crustacea

Crustaceans are mandibulate arthropods that are traditionally a part of the paraphyletic subphylum Crustacea. Crustaceans are mainly aquatic, including decapods, seed shrimps, branchiopods, fish lice, krill, remipedes, isopods, barnacles, copepods, opossum shrimps, amphipods and mantis shrimp. It is now well accepted that hexapods are cladistically crustaceans, with the two groups now combined in the monophyletic clade Pancrustacea. The three classes Cephalocarida, Branchiopoda, and Remipedia are more closely related to the hexapods than they are to any other crustaceans.

Time the record covers

At least 515 million years on record.

The record covers at least 516 Mya to 11.7 ka. No occurrence read is dated outside 521 Mya to 0 Mya.

2,194 occurrences of Crustacea on record, most of them in the Late 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

2,194 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.

Each of the 2,194 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. 508 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.
