Daurlong wangi

Daurlong is an extinct genus of dromaeosaurid dinosaur from the Lower Cretaceous (Aptian) Longjiang Formation of China. The genus contains a single species, D. wangi, known from a nearly complete skeleton. Daurlong represents the first described occurrence of a preserved intestinal region in a theropod closely related to birds.

Time the record covers

At most 1.9 million years on record.

The one occurrence read is dated to somewhere between 121.4 Mya and 119.57 Mya, which is a dating window rather than a span.

1 occurrence of Daurlong wangi 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

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.
