Pseudomelania colusaensis
No picture of Pseudomelania colusaensis was found. Wikipedia, Wikidata and iDigBio were searched and had none. Smithsonian Open Access did not answer, so this is what the others held rather than everything there is. GBIF was asked, and what came back is not recorded: nothing, or a picture this site could not tie to Pseudomelania colusaensis, or no answer at all. This entry cannot say which.

Time the record covers
At least 14 million years on record.
The record covers at least 100.5 Mya to 85.7 Mya. No occurrence read is dated outside 113.2 Mya to 83.6 Mya.
4 occurrences of Pseudomelania colusaensis 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
4 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 4 sites for Pseudomelania colusaensis, 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- Upper Cretaceous of the Pacific Coast3
- Early Cretaceous pterosaur guano deposit from central Oregon, USA1
Each of the 4 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.
