Martinichthys

Searched as Martinichthys brevis. The Paleobiology Database treats Martinichthys as the accepted name.

Martinichthys is an extinct genus of plethodid fish from the Cretaceous of North America. It is known from the Niobrara Chalk, in which it is exceedingly rare. It is named after one H. T. Martin, who collected the most complete specimen at the time of description.

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

Time the record covers

At most 4.1 million years on record.

The one occurrence read is dated to somewhere between 89.8 Mya and 85.7 Mya, which is a dating window rather than a span.

1 occurrence of Martinichthys on record, most of them in the Late Cretaceous. 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.
