Phylloceras
Searched as Phylloceras (Hypophylloceras) tethys majoricense. The Paleobiology Database treats Phylloceras as the accepted name.
Phylloceras is an extinct genus of ammonoid cephalopods belonging to the family Phylloceratidae. These nektonic carnivores lived from Early Jurassic to Late Cretaceous.

Time the record covers
At most 3.8 million years on record.
The one occurrence read is dated to somewhere between 110.1 Mya and 106.3 Mya, which is a dating window rather than a span.
1 occurrence of Phylloceras 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
1 occurrences- Early Cretaceous100%
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 754 sites for Phylloceras, 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.
