Lsmarus is a genus of large, herbivorous mammals known as giant ground sloths, which lived in South America during the Pleistocene epoch. These creatures are notable for their massive size and unique adaptations for a herbivorous diet, including strong limbs and large claws for foraging. Lsmarus is often cited in studies of extinct megafauna and their ecological roles, as well as understanding the impacts of climate change and human activity on species extinction.
