Laguna La Yeguada is an elliptical lake situated in the Veraguas Province within the Isthmus of Panama (8°27' N, 80°51' W). The data were collected to investigate the Late Quaternary megafaunal extinction in Panama and establish the first detailed record of megafaunal presence/absence, vegetation dynamics, and fire activity, respectively, spanning the Late Pleistocene to the Holocene. The data was collected for the PhD research titled: Ecological consequences of Pleistocene megafaunal declines in the Neotropics (https://gtr.ukri.org/projects?ref=studentship-2859430), funded by https://gtr.ukri.org/projects?ref=NE/S007504/1. The data is to be published in the Quaternary Science Reviews Journal: Pym, F., Franco-Gaviria, F., Raczka, M., Adediran, G.A., Sitch, S. and Urrego, D.H.

The age-depth model was produced using the Bacon Package v.2.3.9.1 (Blaauw and Christen, 2013). SCF samples were prepared following a modification of Fægri et al. (1989). This modification removed acetolysis (Pym et al., 2023). Pollen and charcoal samples were prepared following standard protocols (Fægri et al., 1989; Whitlock and Larsen, 2002). SCF and pollen were identified using a Zeiss Axioskop light microscope at 400×, 600× 1000× magnification. Macroscopic charcoal particles were manually separated and photographed using a Zeiss Stemi stereo microscope at 50x magnification. Radiocarbon dates were collected at the Beta Analytic Carbon laboratory (2010 data) and Queen's University Belfast (2024 data). Felix Pym collected the palynological data in the Geography laboratory at the University of Exeter.
