592:. The paleosol type is similar to modern vertisols forming in semi-arid areas with seasonal precipitation, commonly with dry periods lasting 4–8 months. The presence of root traces suggests that the floodplain was covered with small trees and bushes, vegetation suitable for herbivorous animals living on the alluvial plain.
