A New Omomyid Primate from the Earliest Eocene of Southern England: First Phase of Microchoerine Evolution

New material of Pseudoloris parvulus (Microchoerinae, Omomyidae, Primates) from the Late Eocene of Sossís (northeastern Spain) and its implications for the evolution of Pseudoloris

“…Several previous works have analyzed the phylogenetic affinities of the genus Pseudoloris within the subfamily Microchoerinae (Hooker, 1986(Hooker, , 2012Hooker and Harrison, 2008). According to Hooker (1986), the large number of characters separating Pseudoloris from the rest of the microchoerine genera known at that time (Nannopithex, Necrolemur and Microchoerus) indicate a more distant relationship.…”

“…Recent studies carried out by the research team of the ICP have involved the discovery of new fossil sites, as well as the detailed analysis of the material from the classical collections housed at the ICP (Marig o et al, , 2011(Marig o et al, , 2013(Marig o et al, , 2014. Specifically, several works have been focused on the study of omomyids from some Spanish localities such as Sant Jaume de Frontany a, Mazater on, Sant Cugat de Gavadons and Zambrana , 2012, 2013a, 2013b.…”

“…It is particularly well represented in France, but is also found in Spain, England and Germany. The recent description of relatively rich samples from the Iberian Peninsula has notably increased our knowledge of its dental morphology, including a description of the anterior dentition , 2012, which was previously nearly unknown. Here we describe new material of Pseudoloris from Sossís, one of the most important Eocene sites from the Iberian Peninsula.…”

New dental material and redescription of Agerinia roselli (Primates, Adapiformes) from Les Saleres (early Eocene, NE Iberian Peninsula)

“…The early Eocene recorded an important step in the early diversification of primates. The primate record in Europe at this time is not very abundant, although rather diverse and geographically widespread (e.g., Russell et al, 1967;Godinot, 1978Godinot, , 1981Franzen, 1987Franzen, , 2000aMarandat, 1991;Estravís, 2000;Smith et al, 2006;Franzen et al, 2009;Gebo et al, 2012Gebo et al, , 2015Hooker, 2012;Marigó et al, 2012Marigó et al, , 2014. In the Iberian Peninsula, the first studies of Eocene primates were undertaken in the 1960s (Crusafont-Pairó, 1967).…”

Necrolemur anadoni, a new species of Microchoerinae (Omomyidae, Primates) from the Middle Eocene of Sant Jaume de Frontanyà (Pyrenees, Northeastern Spain)

“…Within the Omomyidae, the subfamily Microchoerinae, exclusively recorded from Europe, ranged primarily from the Early to Late Eocene, with some genera ( Pseudoloris, Microchoerus ) lasting into the Early Oligocene in Spain (Köhler and Moyà‐Solà, ; Peláez‐Campomanes, ). Knowledge about microchoerines considerably increased in recent years due to the description of new taxa (Hooker, ; Hooker and Harrison, ). In the Iberian Peninsula, late studies about this group were focused on the description of new material of the genera Pseudoloris (Minwer‐Barakat et al, ) and Microchoerus (Minwer‐Barakat et al, ).…”
