Ornithischia

Ornithischia is an extinct clade of mainly herbivorous dinosaurs characterized by a pelvic structure superficially similar to that of birds. The name Ornithischia, or "bird-hipped", reflects this similarity and is derived from the Greek stem ornith- (ὀρνιθ-), meaning "bird", and ischion (ἴσχιον), meaning "hip". However, as birds are theropod dinosaurs, they are only distantly related to this group.

7,080 occurrences of Ornithischia on record, most of them in the Late Cretaceous. 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

7,080 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 named rock units Ornithischia has been recovered from, largest first. Drawn where the rock is now, not where it formed. 704 further formations hold fewer occurrences each and are not listed. 522 occurrences have no formation on record, which is common for older literature.

Ornithischia and its relatives

Late Cretaceous

Where Ornithischia and its relatives were recorded in the Late Cretaceous.

Found in the same rock

1,452 taxa

The Paleobiology Database records at least 1,423 sites for Ornithischia, and this reads 240 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

2,447 references

Each of the 7,080 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. 2,435 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.
