“…A previous paleodietary study of Plagiolophus using three dietary proxies (hypsodonty, mesowear, and dental microwear texture analysis) showed that there are no dietary differences between the middle Eocene species Plagiolophus mazateronensis and the early Oligocene species Plagiolophus minor and Plagiolophus ministri (Perales-Gogenola et al, 2022b). However, the genus Plagiolophus seems to have been a highly selective and invariable feeder that fed on vegetation with the same features irrespective of age or location (Perales-Gogenola et al, 2022b). Future studies of the paleodiet of the endemic Iberian taxa will hopefully shed light on the influence of paleoecology and paleodiet on the peculiar dental series of these genera and species, especially the species belonging to Leptolophus , Iberolophus , and Idiodontherium .…”

“…These different dietary strategies could even be a result of the climatic cooling that began at the end of the middle Eocene and culminated in the Eocene--Oligocene-transition (e.g., Blondel, 2001;Franzen, 2003;Remy, 2004;Badiola & Cuesta, 2008;Perales-Gogenola et al, 2021;Badiola et al, 2009aBadiola et al, , 2022.

Equoid perissodactyls were diverse in the Eocene of the Iberian Peninsula, and those from the central and western Iberian basins (Mondego, Oviedo, Almazán, Duero, and Miranda-Treviño) and the eastern Ebro Basin (Ulldemolins area) were endemic, with the presence of six genera and 19 species (mainly Palaeotheriidae sensu stricto) that are unknown in the rest of western Europe. In this paper, a new endemic Eocene paleotheriid genus, Idiodontherium, gen. nov., is reported. The new genus includes two species: I. martindejesusi, from the upper middle Eocene (Bartonian) of Mazaterón (Almazán Basin, Soria, Spain) and I. astibiai, from the upper Eocene (Priabonian) site of Zambrana (Miranda-Treviño Basin, Álava/Araba, Spain). Idiodontherium exhibits an unusual dental pattern, which is characterized by an extreme shortening of the jugal series due to a great reduction of the premolar series, in combination with a long post-canine diastema. It is a small to medium-sized plagiolophine with thick enamel in comparison with other plagiolophine equoids of the same size. These new taxa exhibit peculiar dental features that could be associated with greater specialization of the diet.

New mammal and bird tracks from the Lower Oligocene of the Ebro Basin (NE Spain): implications for the Palaeogene ichnological record

et al. 2022

The Ebro Basin (Spain) is one of the few worldwide areas where Paleogene avian and mammal tracksites have been found. A new unpublished tracksite known as La Sagarreta is here described. The tracksite is located in a sandstone-dominated outcrop from the Early Oligocene Peralta Fm. in the northern-central sector of the basin. Six different ichnotaxa have been identified. Four belong to mammals, including perissodactyl (cf.Plagiolophustipus isp), artiodactyl (Megapecoripeda isp. and cf. Pecoripeda isp.) and carnivoramorph tracks (cf. Canipeda isp.), and the other two to avian tracks (Aviadactyla vialovi and Gruipeda dominguensis). La Sagarreta presents a high ichnodiversity with the presence of a medium size member (or relative) of the genus Plagiolophus, one medium and one small sized artiodactyl that probably belong to the family Entelodontidae, one medium size unidentified carnivorous mammal and two types of birds. La Sagarreta tracksite is the most diverse Early Oligocene tracksite at Ebro Basin and one of the few palaeontologic vertebrate records at the central area of the basin.
