Leucophaeus scoresbii
The dolphin gull, sometimes erroneously called the red-billed gull, is a gull native to southern Chile and Argentina, and the Falkland Islands. It is a coastal bird inhabiting rocky, muddy and sandy shores and is often found around seabird colonies. They have greyish feathers, and the feathers on their wings are a darker shade. Dolphin gulls have a varied diet, eating many things ranging from mussels to carrion.

Time the record covers
At most 12 thousand years on record.
The one occurrence read is dated to somewhere between 11.7 ka and 0 Mya, which is a dating window rather than a span.
1 occurrence of Leucophaeus scoresbii on record, most of them in the Holocene. The Paleobiology Database records this as a living group. 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- Holocene100%
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.
