Soroavisaurus australis

Soroavisaurus is an extinct genus of enantiornithine birds that lived in South America during the Late Cretaceous period, about 71–69 million years ago. The only known species, Soroavisaurus australis, was named in 1993; the generic name means "sister to Avisaurus" while the specific name means "southern". All specimens confidently assigned to this species are fossilised leg bones collected from the Lecho Formation of El Brete, a locality in the province of Salta, Argentina. Some authors have proposed that either Enantiornis or Martinavis, which are known from wing bones found at the same locality, may represent the same animal as Soroavisaurus. However it is difficult to confirm which of these truly is the same species.

Time the record covers

At most 6.2 million years on record.

The one occurrence read is dated to somewhere between 72.2 Mya and 66 Mya, which is a dating window rather than a span.

1 occurrence of Soroavisaurus australis on record, most of them in the Late 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.
