Desmoceras

Searched as Desmoceras inflatum. The Paleobiology Database treats Desmoceras as the accepted name.

Desmoceras is a genus of ammonites belonging to the family Desmoceratidae. These cephalopods were fast-moving nektonic carnivores. They lived in the Early Cretaceous; Albian epoch.

Time the record covers

At most 6.9 million years on record.

Every occurrence read is dated to somewhere between 113.2 Mya and 106.3 Mya, and nothing in the dating separates them, so that window is what the record shows rather than a span.

5 occurrences of Desmoceras on record, most of them in the Early Cretaceous. 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

5 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 271 sites for Desmoceras, and this reads 240 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.
