Vieraella herbstii

Vieraella is an extinct genus of frogs from the Lower Jurassic Roca Blanca Formation of Argentina, and one of the oldest true frogs known. This genus is known by a single exceptionally well-preserved specimen, P.V.L. 2188, with at least eight presacrals vertebrae, free ribs, ulna and radius not fused, bony skull with some discoglossid characters.

Time the record covers

At most 14 million years on record.

The one occurrence read is dated to somewhere between 184.2 Mya and 170.9 Mya, which is a dating window rather than a span.

1 occurrence of Vieraella herbstii on record, most of them in the Early Jurassic. 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

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.
