Protoconodonta

Protoconodonts are an extinct group of Cambrian animals known from fossilized phosphatic tooth-like structures. They were originally described as an informal group of early conodonts, though more recent studies consider them to be more closely related to chaetognaths.

No picture of Protoconodonta 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 Protoconodonta, or no answer at all. This entry cannot say which.

Time the record covers

At least 30 million years on record.

The record covers at least 530.7 Mya to 500.5 Mya. No occurrence read is dated outside 538.8 Mya to 497 Mya.

253 occurrences of Protoconodonta on record, most of them in the Cambrian. 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

253 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.

458 taxa

The Paleobiology Database records 143 sites for Protoconodonta, 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

47 references

Each of the 253 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. 35 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.
