Pseudotorellia

Pseudotorellia is a genus of small sea snails with a transparent, more or less internal, shell, marine gastropod mollusks in the family Velutinidae. Because the shell is mostly internal, these snails resemble sea slugs in general appearance.

No picture of Pseudotorellia was found. Wikipedia, Wikidata and Smithsonian Open Access were searched and had none. iDigBio and GBIF were not searched: the Paleobiology Database does not place Pseudotorellia firmly enough to tell it from something else bearing the same name, and a search on the name alone returns whichever of them was photographed.

90 occurrences of Pseudotorellia on record, most of them in the Middle 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

90 occurrences

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.

307 taxa

The Paleobiology Database records 67 sites for Pseudotorellia, 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

49 references

Each of the 90 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. 37 further references are not listed. Each entry links to the Paleobiology Database's own record for the work.
