Laricola remains have been reported from localities in France including the Early Miocene of Saint-Gérand-le-Puy and from the Late Oligocene Billy-Créchy locale (Milne-Edwards, 1863; Mourer-Chauviré et al., 2004; De Pietri et al., 2011). The vertebrate fauna from Créchy, France, corresponds with Paleogene mammalian zones MP25-MP30 and are considered to bracket the Miocene-Oligocene boundary with an age estimated between 24.1-23.6 Ma (Hugueney et al., 2003).

Material referred to Laricola elegans was included in a combined phylogenetic analysis by Smith (2011a) and the morphology based analysis of De Pietri et al. (2011). Laricola elegans was placed in a polytomy with the extant species Larus marinus and Larus argentatus in the results of Smith (2011a, figure 8.5) and was recovered in an unresolved position at the base of Laromorphae (the clade including Laridae, Sternidae, Rynchopidae, Gygis and Anous) in the results of De Pietri et al. (2011). The relative systematic positions of Laridae, Sternidae and Rynchopidae to one another, Larus relative to other Laridae, and the positions of Gygis and Anous relative to other Laromorphae differ in the results of recent phylogenetic analyses (e.g., Baker et al., 2007; Smith, 2011b; De Pietri et al., 2011). Moreover, because the systematic position of Laricola was unresolved in the results of De Pietri et al. (2011), Laricola elegans is suggested as a calibration for the basal divergence among Laromorphae.
