Chalmys sp.
Smithsonian Institution · CC0 · via Smithsonian. May be a photograph of a specimen, or an artist’s reconstruction — an interpretation of a skeleton, since colour and soft tissue are almost never preserved.
Time the record covers
At least 127 million years on record.
The record covers at least 211.18 Mya to 83.6 Mya. No occurrence read is dated outside 215.38 Mya to 72.2 Mya.
2 occurrences of Chalmys sp. on record, most of them in the Late Triassic. 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
2 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 2 sites for Chalmys sp., 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.
Entered from
2 references- Short-necked plesiosaurs of the Family Polycotylidae from the Campanian of the Saratov Region1
- [Sections of the Trias from the upper River Kolym and northern Priochotya]1
Each of the 2 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. 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.

No 3D scan of Chalmys sp. was found in Smithsonian Open Access and Sketchfab.
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.
