Neolissoceras

Neolissoceras is a genus of haploceratid ammonites with a smooth, compressed, flat-sided shell with a flatly rounded venter and distinct umbilical margin, from the Upper Jurassic (Tithonian) - Lower Cretaceous (Hauterivian) of southern Europe, Madagascar, and India.

Time the record covers

At least 10 million years on record.

The record covers at least 143.1 Mya to 132.6 Mya. No occurrence read is dated outside 149.2 Mya to 121.4 Mya.

519 occurrences of Neolissoceras 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

519 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.

38 references

Each of the 519 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. 26 further references are not listed. Entries link to doi.org where the Paleobiology Database holds an identifier, and to its own record where it does not. Relayed as the Paleobiology Database holds them, not checked against what they resolve to.
