Neurankylus

Neurankylus is an extinct genus of turtles in the family Baenidae that lived between 112 and 61 million years ago in Canada and the United States. It was originally placed within the monotypic family Neurankylidae, but it has since been placed in the Neurankylinae, alongside Trinitichelys. The type species, Neurankylus eximius, was described by Lawrence Lambe in 1902. The species N. lithographicus was discovered in the Milk River Formation (Canada), alongside the holotype of the pachycephalosaurid dinosaur Acrotholus audeti.

Time the record covers

At least 22 million years on record.

The record covers at least 85.7 Mya to 63.4 Mya. No occurrence read is dated outside 89.8 Mya to 60.9 Mya.

70 occurrences of Neurankylus on record, most of them in the Late 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

70 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.
