Analytoceras

Analytoceras is an extinct genus of cephalopod belonging to the Ammonite subclass that lived during the early Jurassic. Analytoceras, named by Alpheus Hyatt in 1900, is a lytoceratid and only member of the pleuroacanthitid subfamily Analytoceratinae, which has the same characters as its genus.

Time the record covers

At most 31 million years on record.

Every occurrence read is dated to somewhere between 205.7 Mya and 174.7 Mya, and nothing in the dating separates them, so that window is what the record shows rather than a span.

7 occurrences of Analytoceras on record, most of them in the Early 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

7 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.

57 taxa

The Paleobiology Database records 4 sites for Analytoceras, 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

6 references

Each of the 7 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. Each entry links to the Paleobiology Database's own record for the work.
