Larus lacus is an extinct species of gull that lived in North America during the Late Pliocene.^[1]

Etymology

The genus name Larus derives from Ancient Greek, referring to a seabird. The species name lacus derives from Latin, meaning "lake or standing body of water, in reference to the lagoonal deposits at the type locality."^[1]

Description

Larus lacus specimens stem from Sarasota County, Florida.^[1] The humerus of Larus lacus most closely resembles the Hartlaub's gull (Chroicocephalus hartlaubii, formerly Larus hartlaubii), black-headed gull (Chroicocephalus ridibundus; formerly Larus ridibundus), brown-hooded gull (Chroicocephalus maculipennis; formerly Larus maculipennis), and Franklin's gull (Leucophaeus pipixcan; formerly Larus pipixcan).^[1]
