Deinonychosauria
Deinonychosauria is a clade of paravian dinosaurs that lived from the Late Jurassic to the Late Cretaceous periods. Fossils have been found across the globe in North America, Europe, Africa, Asia, South America, and Antarctica, with fossilized teeth giving credence to the possibility that they inhabited Australia as well. This group of dinosaurs are known for their sickle-shaped toe claws and features in the shoulder bones.

Time the record covers
At least 98 million years on record.
The record covers at least 170.9 Mya to 72.2 Mya. No occurrence read is dated outside 184.2 Mya to 61.66 Mya.
1,301 occurrences of Deinonychosauria on record, most of them in the Late 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
1,301 occurrences- Early Jurassicunder 1%
- Middle Jurassicunder 1%
- Late Jurassic3%
- Early Cretaceous16%
- Late Cretaceous81%
- Paleoceneunder 1%
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 804 sites for Deinonychosauria, 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 1,301 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. 455 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.
