Red and grey brocket deer and collared and white‐lipped peccary of the Peruvian Amazon are frugivores and consume many types of seeds. The ruminant stomach of brocket deer functions as a mechanism to digest the abundant hard palm seeds of Iriartea sp., Euterpe sp. and Mauritia flexuosa . The sympatric peccaries also consume hard palm seeds; however, peccaries crack these palms by using their strong jaws, thick skull bones and interlocking canines. The ruminant stomach might have evolved as a means to digest structural components of seeds, similar to that employed by extant brocket deer, since ancestral ruminants appear to have evolved as smallbodied, forest‐dwelling frugivores.
