Protarca
No picture of Protarca was found. Wikipedia, Wikidata, iDigBio and Smithsonian Open Access were searched and had none. GBIF was asked, and what came back is not recorded: nothing, or a picture this site could not tie to Protarca, or no answer at all. This entry cannot say which.

Time the record covers
At least 8.2 million years on record.
The record covers at least 93.9 Mya to 85.7 Mya. No occurrence read is dated outside 100.5 Mya to 83.6 Mya.
44 occurrences of Protarca 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
44 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 44 sites for Protarca, 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.
Entered from
2 references- Larger invertebrate fossils of the Woodbine formation (Cenomanian) of Texas43
- Fossils from the Eutaw Formation, Chattahoochee River region, Alabama-Georgia1
Each of the 44 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. Each entry links to doi.org. Relayed as the Paleobiology Database holds them, not checked against what they resolve to.

MorphoSource was not reached for this taxon, so this list is what the others held rather than everything there is.
This is what the site found, which is not the same as what exists.
