Promegalaspides (Borogothus)

Searched as Borogothus. The Paleobiology Database treats Promegalaspides (Borogothus) as the accepted name.

Borogothus is an extinct genus of trilobite arthropod. It lived during the Arenig stage of the Ordovician Period, approximately 478 to 471 million years ago.

No picture of Promegalaspides (Borogothus) 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 Promegalaspides (Borogothus), or no answer at all. This entry cannot say which.

14 occurrences of Promegalaspides (Borogothus) on record, most of them in the Ordovician. 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

14 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.
