Neutron-based computed microtomography: Pliobates cataloniae and Barberapithecus huerzeleri as a test-case study.

abstract：:While hybridization has been reported for a large number of primate taxa, there is a general lack of data on hybrid morphology for wild individuals with known genetic ancestry. A confirmed hybrid zone for the closely related Neotropical primates Alouatta palliata and A. pigra has provided a unique opportunity to study...
