Aegoceras

Searched as Aegoceras (Aegoceras) lataecosta pyritosa. The Paleobiology Database treats Aegoceras as the accepted name.

Aegoceras is an evolutionary wound ammonite, with wide spaced ribs, from the Early Jurassic (England) included in the Liparoceratidae and superfamily Eoderoceratidae. Leparoceras is a related genus.

Time the record covers

At most 8.7 million years on record.

The one occurrence read is dated to somewhere between 192.9 Mya and 184.2 Mya, which is a dating window rather than a span.

1 occurrence of Aegoceras 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

1 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 150 sites for Aegoceras, 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

1 reference

Each of the 1 occurrence 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.
