Osteohistology of the non-mammaliaform traversodontidsProtuberum cabralenseandExaeretodon riograndensisfrom southern Brazil

The current study presents a detailed analysis of the osteohistology of the Triassic non-mammaliaform traversodontid cynodonts Protuberum cabralense and Exaeretodon riograndesis. The data provided here adds new information on the growth patterns of South American traversodontids. A single subadult individual of P. cabralense revealed bone tissues comprising uninterrupted fibrolamellar bone. Patches of slower growing lamellar bone at the...
