Figure 1. A, geographical context. B, local Oligocene and Miocene sedimentary units. In A, distribution data for Abronia are from GBIF.org (2021). Distribution data were filtered manually to remove selected outliers using the study by GutiérrezRodríguez et al. (2021) as a reference. Grey shading in A indicates elevation (i.e. mountainous areas). Geological data in B are based on the studies by Hoyt et al. (2018) and Jennings (2010). The location of the UCMP V-5847 fossiliferous site was obtained from the study by James (1963).
