At least 20 million years on record.

The record covers at least 121.4 Mya to 100.5 Mya. No occurrence read is dated outside 125.77 Mya to 93.9 Mya.

27 occurrences of Kossmatella 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

27 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.
