Tofangoceras

Tofangoceras is a genus of pseudorthoceroid cephalopods from the Middle Ordovician of the USA (NY) and Asia belonging to the Stereoplasmoceratidae and similar to Stereoplansmoceras.

No picture of Tofangoceras was found. Wikipedia, Wikidata, iDigBio and Smithsonian Open Access were searched and had none. GBIF was asked, and what came back is not recorded: nothing, or a picture this site could not tie to Tofangoceras, or no answer at all. This entry cannot say which.

25 occurrences of Tofangoceras 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

25 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.

The Paleobiology Database records 23 sites for Tofangoceras, and this reads all of them. The number is how many of those sites it was catalogued from too. The 24 sharing the most are listed.

This is not a list of everything alive at the time. It is only what has come out of the same ground as this animal and been written down.
