Echmatemys

No picture of Echmatemys was found. iDigBio was searched and had none. Wikipedia has a picture filed under this name, but nothing tied it to Echmatemys itself, so it was not used. Wikidata and 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 Echmatemys, 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 51.1 Mya to 37 Mya. No occurrence read is dated outside 56 Mya to 33.9 Mya.

117 occurrences of Echmatemys on record, most of them in the Eocene. 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

117 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.

582 taxa

The Paleobiology Database records 90 sites for Echmatemys, 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

39 references

Each of the 117 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. 27 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.
