Nematogenys cuivi

Nematogenys cuivi is a Miocene species of fossil ray-finned fish belonging to the family Nematogenyidae, the mountain catfishes. This species was described from a fossil found in the fluviolacustrine, i.e. sediments deposited by both rivers and lakes, in the upper Cura–Mallín Formation between 37°S and 39°S in Chile. The only other member of this family is the extant Nematogenys inermis of Central Chile.

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

Time the record covers

At most 2.2 million years on record.

The one occurrence read is dated to somewhere between 13.82 Mya and 11.63 Mya, which is a dating window rather than a span.

1 occurrence of Nematogenys cuivi on record, most of them in the Miocene. The Paleobiology Database records this as a living group, and the chart stops with its fossils rather than at the present. 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

1 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.
