Crucella
No picture of Crucella 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 Crucella, or no answer at all. This entry cannot say which.
On record
Recorded, not inferred- Sits inside
- HagiastridaePBDB
Time the record covers
At least 153 million years on record.
The record covers at least 237 Mya to 83.6 Mya. No occurrence read is dated outside 239.48 Mya to 72.2 Mya.
689 occurrences of Crucella 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
689 occurrences- Middle Triassicunder 1%
- Late Triassic6%
- Early Jurassic32%
- Middle Jurassic4%
- Late Jurassic13%
- Early Cretaceous29%
- Late Cretaceous16%
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 307 sites for Crucella, and this reads 240 of them. Of that, one read hit the database's own return limit, so every count below is a floor rather than a total. 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 689 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. 63 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.
