Cryptoclidus richardsoni
Not Cryptoclidus richardsoni. This is Cryptoclidus richardsoni (Lydekker, 1889), a relative — both are Cryptoclididae.

Time the record covers
At least 9.7 million years on record.
The record covers at least 154.8 Mya to 145.06 Mya. No occurrence read is dated outside 165.3 Mya to 143.1 Mya.
3 occurrences of Cryptoclidus richardsoni on record, most of them in the Late 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
3 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 3 sites for Cryptoclidus richardsoni, 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 3 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 the Paleobiology Database's own record for the work.

No 3D scan of Cryptoclidus richardsoni was found in Sketchfab.
Smithsonian Open Access and MorphoSource were 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.
