Bolbometopon

The green humphead parrotfish is the largest species of parrotfish, growing to lengths of 1.3 m (4.3 ft) and weighing up to 46 kg (101 lb), though some sources report a total length of 1.5 m and weight of 75 kg (165 lb). It is the only species in the monotypic genus Bolbometopon. Fossil remains of Bolbometopon sp. are known from the Late Miocene of Sri Lanka.

Time the record covers

At most 6.3 million years on record.

The one occurrence read is dated to somewhere between 11.63 Mya and 5.333 Mya, which is a dating window rather than a span.

1 occurrence of Bolbometopon on record, most of them in the Miocene. 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.
