Eurypoda
Thyreophora, often known simply as armored dinosaurs is a group of armored ornithischian dinosaurs that lived from the Early Jurassic until the end of the Cretaceous.

Time the record covers
At least 112 million years on record.
The record covers at least 184.2 Mya to 72.2 Mya. No occurrence read is dated outside 199.5 Mya to 66 Mya.
1,146 occurrences of Eurypoda 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
1,146 occurrences- Early Jurassicunder 1%
- Middle Jurassic5%
- Late Jurassic20%
- Early Cretaceous22%
- Late Cretaceous53%
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 1,016 sites for Eurypoda, 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.

Each of the 1,146 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. 578 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.
