Plegagnathus

No picture of Plegagnathus was found. Wikipedia, Wikidata, iDigBio and Smithsonian Open Access were searched and had none. GBIF was asked, and what came back is not recorded: nothing, or a picture this site could not tie to Plegagnathus, or no answer at all. This entry cannot say which.

Time the record covers

At most 32 million years on record.

Every occurrence read is dated to somewhere between 458.2 Mya and 426.7 Mya, and nothing in the dating separates them, so that window is what the record shows rather than a span.

37 occurrences of Plegagnathus on record, most of them in the Ordovician. 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

37 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.

77 taxa

The Paleobiology Database records 20 sites for Plegagnathus, 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

8 references

Each of the 37 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 doi.org. Relayed as the Paleobiology Database holds them, not checked against what they resolve to.

No picture of Plegagnathus was found. Wikipedia, Wikidata, iDigBio and Smithsonian Open Access were searched and had none.

GBIF was asked, and what came back is not recorded: nothing, or a picture this site could not tie to Plegagnathus, or no answer at all. This entry cannot say which.

No 3D scan of Plegagnathus 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.
