Bochianites
Bochianites is a straight shelled ammonite which lived from the Upper Jurassic, Tithonian, to the Lower Cretaceous, Hauterivian in what is now Europe, Greenland, Africa, North America and Asia. The shell is long, narrow, moderately expanding; smooth or with weak to strong oblique annular ribs. Sutural elements are short and boxy. The umbilical lobe, which lies between the lateral lobe and dorsal lobe, on either side, is about the same size as the lobule dividing the first lateral saddle.

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 125.77 Mya.
268 occurrences of Bochianites 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
268 occurrencesThese 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 257 sites for Bochianites, 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.
