Eubrontes
Eubrontes is the name of fossilised dinosaur footprints dating from the Late Triassic and Early Jurassic. They have been identified from France, Poland, Slovakia, Czech Republic, Italy, Spain, Sweden, Australia (Queensland), US, India, China and Brazil (South).

Time the record covers
At least 135 million years on record.
The record covers at least 248.6 Mya to 113.2 Mya. No occurrence read is dated outside 250.8 Mya to 93.9 Mya.
304 occurrences of Eubrontes on record, most of them in the Early Jurassic. 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
304 occurrences- Early Triassicunder 1%
- Late Triassic13%
- Early Jurassic69%
- Middle Jurassic6%
- Late Jurassicunder 1%
- Early Cretaceous10%
- Late Cretaceousunder 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 215 sites for Eubrontes, 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.

Each of the 304 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. 131 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.
