Isotope data from amino acids indicate Darwin’s ground sloth was not an herbivore
Abstract Fossil sloths are regarded as obligate herbivores for reasons including peculiarities of their craniodental morphology and that all living sloths feed exclusively on plants. We challenge this view based on isotopic analyses of nitrogen of specific amino acids, which show that Darwin’s groun...
