- Melanosuchus niger Spix is distributed throughout the Amazon River basin today. The extinct Melanosuchus fisheri Medina from the late Miocene of Venezuela was erected based on two almost complete, but heavily deformed skulls (the holotype MCNC 243 and the referred specimen MCZ 4336), which show morphological differences from each other. The comparison indicates that only the holotype can be referred to Melanosuchus Gray. We propose MCZ 4336 is a representative of the caimanine Globidentosuchus brachyrostris Scheyer, Aguilera, Delfino, Fortier, Carlini, Sánchez, Carrillo-Briceño, Quiroz and Sánchez-Villagra. Although the taxonomy of M. fisheri is taken into question herein, the classification of the holotype still sustains the hypothesis that the genus is registered in South America since the late Miocene.
Melanosuchus niger Spix se distribuye actualmente por toda la cuenca del Río Amazonas. La especie extinta Melanosuchus fisheri Medina del Mioceno tardío de Venezuela se erigió sobre la base de dos cráneos casi completos pero muy deformados (el holotipo MCNC 243 y el material referido MCZ 4336), que muestran diferencias morfológicas entre sí. La comparación indica que solo el holotipo puede ser referido a Melanosuchus Gray. Aquí se propone que MCZ 4336 es un representante del caimanino Globidentosuchus brachyrostris Scheyer, Aguilera, Delfino, Fortier, Carlini, Sánchez, Carrillo-Briceño, Quiroz and Sánchez-Villagra. Si bien la taxonomía de M. fisheri es aquí discutida, la clasificación del holotipo aún sostiene la hipótesis de que el género se registra en América del Sur desde el Mioceno tardío.
