Caulkicephalus trimicrodon
Caulkicephalus is a genus of anhanguerid pterosaur from the Isle of Wight off the coast of England. It lived during the Early Cretaceous period, about 125 million years ago.

Time the record covers
At most 4.4 million years on record.
Every occurrence read is dated to somewhere between 125.77 Mya and 121.4 Mya, and nothing in the dating separates them, so that window is what the record shows rather than a span.
2 occurrences of Caulkicephalus trimicrodon 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
2 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.
