Cheiloceratidae

Cheiloceratidae is a family of ammonoid cephalopods included in the goniatitid suborder Tornoceratina in which the suture has 4 to 12 lobes, the ventral one undivided and those in the lateral areas originating as subdivisions of internal and external lateral saddles.

Cheiloceras ovatum (Munster, 1832), a relative of Cheiloceratidae — not Cheiloceratidae itself

Not Cheiloceratidae. This is Cheiloceras ovatum (Munster, 1832), a relative — both are Cheiloceratidae.

Time the record covers

At most 14 million years on record.

Every occurrence read is dated to somewhere between 372.15 Mya and 358.86 Mya, and nothing in the dating separates them, so that window is what the record shows rather than a span.

160 occurrences of Cheiloceratidae 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

160 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 72 sites for Cheiloceratidae, 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.

Entered from

11 references

Each of the 160 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. Relayed as the Paleobiology Database holds them, not checked against what they resolve to.
