Time the record covers

At most 39 million years on record.

The one occurrence read is dated to somewhere between 66 Mya and 27.3 Mya, which is a dating window rather than a span.

1 occurrence of Eotrigonobalanus andreanszkyi on record, most of them in the Eocene. 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.
