Lithacoceras

Searched as Lithacoceras torquatiforme umbilicata. The Paleobiology Database treats Lithacoceras as the accepted name.

Lithacoceras is an extinct ammonite cephalopod genus included in the superfamily Perisphinctoidea. These fast-moving nektonic carnivores lived during the Jurassic period, from the Oxfordian age to the Tithonian age.

Time the record covers

At most 6.7 million years on record.

The one occurrence read is dated to somewhere between 161.5 Mya and 154.8 Mya, which is a dating window rather than a span.

1 occurrence of Lithacoceras 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

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.
