Time the record covers
At most 1.9 million years on record.
The one occurrence read is dated to somewhere between 201.4 Mya and 199.5 Mya, which is a dating window rather than a span.
1 occurrence of Stratesaurus taylori 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- Early Jurassic100%
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.
