Darin Croft, chair of the Department of Anatomy at Case Western Reserve University School of Medicine, and Matías Armella, chair of paleontology at the National University of Tucumán, published a study, which was featured in Proceedings of the National Academy of Sciences’ journal club section.
In their study, Croft and Armella highlight the importance of testing morphological inferences with direct dietary evidence.
Their findings also reveal unexpected convergent ecological specialization in rodent-like notoungulates—extinct mammals that lived primarily in South America during the Paleocene and Pleistocene eras.
