Ptychodictyon americanum

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

Time the record covers

At most 18 million years on record.

Every occurrence read is dated to somewhere between 410.62 Mya and 393.47 Mya, and nothing in the dating separates them, so that window is what the record shows rather than a span.

6 occurrences of Ptychodictyon americanum on record, most of them in the Devonian. 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

6 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.
