Sphenodiscus lobatus

No picture of Sphenodiscus lobatus was found. Wikidata, iDigBio and Smithsonian Open Access were searched and had none. Wikipedia has a picture filed under this name, but nothing tied it to Sphenodiscus lobatus itself, so it was not used. GBIF was asked, and what came back is not recorded: nothing, or a picture this site could not tie to Sphenodiscus lobatus, or no answer at all. This entry cannot say which.

Time the record covers

At most 22 million years on record.

Every occurrence read is dated to somewhere between 83.6 Mya and 61.66 Mya, and nothing in the dating separates them, so that window is what the record shows rather than a span.

36 occurrences of Sphenodiscus lobatus 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

36 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.

The Paleobiology Database records 36 sites for Sphenodiscus lobatus, 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.

18 references

Each of the 36 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. 6 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.
