Fossil bones and pollen samples were collected and further exploration continued in 2005, with a new trench dug to better access faunal and floral materials. The obtained pollen showed there had been a diverse vegetation cover of herbaceous and arboreal plants from different vegetation belts. There was a deciduous forest with a mixture of oak and hickory trees, along with hornbeam, elm, zelkova, and linden.
In 2005, additional research was conducted, focusing on the collection of fossil bones and plant samples. A new excavation site was established to improve access to animal and plant materials. The pollen analysis revealed a diverse range of vegetation, including herbaceous plants and tree species from various ecological regions. Specifically, a deciduous forest with oak, hickory, hornbeam, elm, zelkova, and linden trees was found.
