Hadronector donbairdi

Hadronector is an extinct genus of prehistoric marine coelacanth which lived during the mid-Carboniferous of North America. It contains a single species, H. donbairdi, known from well-preserved remains recovered from the Serpukhovian -aged Bear Gulch Limestone lagerstätte of Montana, US. It is the type genus of the family Hadronectoridae, which contains only one other known genus, the co-occurring Polyosteorhynchus.

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

Time the record covers

At most 3.3 million years on record.

Every occurrence read is dated to somewhere between 326.9 Mya and 323.6 Mya, and nothing in the dating separates them, so that window is what the record shows rather than a span.

2 occurrences of Hadronector donbairdi 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

2 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.
