Harpetidae

Searched as Harpidae indet.. The Paleobiology Database treats Harpetidae as the accepted name.

No picture of Harpetidae was found. iDigBio and Smithsonian Open Access were searched and had none. Wikipedia and Wikidata have a picture filed under this name, but nothing tied it to Harpetidae 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 Harpetidae, or no answer at all. This entry cannot say which.

9 occurrences of Harpetidae on record, most of them in the Devonian. 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

9 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.

3,390 taxa

The Paleobiology Database records 379 sites for Harpetidae, and this reads 240 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

6 references

Each of the 9 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.

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.
