Wintonopus
Wintonopus is an ichnogenus of dinosaur footprint. Its footprints have been found at Lark Quarry in Queensland Australia. The genus is named after the Winton Formation in which the tracks were found. Other tracks were found in the Broome Sandstone of Dampier Peninsula, Western Australia.

Time the record covers
At least 99 million years on record.
The record covers at least 199.5 Mya to 100.5 Mya. No occurrence read is dated outside 201.4 Mya to 93.9 Mya.
16 occurrences of Wintonopus on record, most of them in the Early 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
16 occurrencesThese 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 13 sites for Wintonopus, and this reads all of them. The number is how many of those sites it was catalogued from too.
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 16 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.
