Aulacosphinctoides

Aulacosphinctoides is an extinct ammonoid cephalopod that lived during the Late Jurassic, included in the ammonitid family Perisphinctidae.

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

Time the record covers

At least 4.1 million years on record.

The record covers at least 149.2 Mya to 145.06 Mya. No occurrence read is dated outside 154.8 Mya to 137.05 Mya.

31 occurrences of Aulacosphinctoides on record, most of them in the Late Jurassic. 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

31 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.

Each of the 31 occurrences read was entered from one of these publications, ordered by how many each accounts for. This is not a search for papers mentioning the name. Entries link to doi.org where the Paleobiology Database holds an identifier, and to its own record where it does not.
