Hadrosauroidea

Hadrosauroidea is a clade or superfamily of ornithischian dinosaurs that includes the "duck-billed" dinosaurs, or Hadrosauridae, and all dinosaurs more closely related to them than to Iguanodon. Their remains have been recovered in Asia, Europe, Africa and the Americas. Many primitive hadrosauroids, such as the Asian Probactrosaurus and Altirhinus, have traditionally been included in a paraphyletic "Iguanodontidae". With cladistic analysis, the traditional Iguanodontidae has been largely disbanded, and probably includes only Iguanodon and perhaps its closest relatives.

Time the record covers

At least 96 million years on record.

The record covers at least 168.2 Mya to 72.2 Mya. No occurrence read is dated outside 174.7 Mya to 61.66 Mya.

1,941 occurrences of Hadrosauroidea 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

1,941 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 Hadrosauroidea has been recovered from, largest first. Drawn where the rock is now, not where it formed. 228 further formations hold fewer occurrences each and are not listed. 122 occurrences have no formation on record, which is common for older literature.

Hadrosauroidea and its relatives

Late Cretaceous

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

Found in the same rock

880 taxa

The Paleobiology Database records 1,731 sites for Hadrosauroidea, 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

694 references

Each of the 1,941 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. 682 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.
