Eugeneodontidae

The Eugeneodontidae is an extinct family of cartilaginous fish known from the Carboniferous, Permian, and potentially Devonian periods of the United States, Iran, and possibly Belgium, Poland and Russia. The eugeneodontids are known primarily from fossilized teeth, as well as the remains of the jaws, gills and in some species nearly complete skeletons with coatings of dermal denticles. The genera Bobbodus, Gilliodus and the type genus Eugeneodus are included within the family. Eugeneodontidae is considered the sister group to the family Caseodontidae, and the two are included together within the suborder Caseodontoidea and the order Eugeneodontiformes. The type genus, and by extension the family and the order Eugeneodontiformes are named in honor of Paleontologist Eugene S. Richardson Jr.

No picture of Eugeneodontidae was found. Wikipedia, Wikidata and iDigBio were searched and had none. 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 Eugeneodontidae, or no answer at all. This entry cannot say which.

11 occurrences of Eugeneodontidae on record, most of them in the Carboniferous. 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

11 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 8 sites for Eugeneodontidae, and this reads all of them. The number is how many of those sites it was catalogued from too.

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.

5 references

Each of the 11 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.
