Furileusauria
Brachyrostra is a clade within the theropod dinosaur family Abelisauridae. It includes the famous genera Carnotaurus, Aucasaurus, potentially Abelisaurus as well as their close relatives from the Cretaceous Period of Argentina and Brazil plus Caletodraco from France. The group was first proposed in an analysis conducted by Juan Canale and colleagues in 2008. They found that all South American abelisaurids described up to that point grouped together as a sub-clade of Abelisauridae, which they named based on the relatively unusual shape of their skulls. They defined the clade Brachyrostra as "all the abelisaurids more closely related to Carnotaurus sastrei than to Majungasaurus crenatissimus."

Time the record covers
At least 21 million years on record.
The record covers at least 93.9 Mya to 72.2 Mya. No occurrence read is dated outside 100.5 Mya to 66 Mya.
12 occurrences of Furileusauria 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
12 occurrences- Late Cretaceous100%
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 10 sites for Furileusauria, and this reads all 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.
