A new gavialid from the Upper Miocene (“Huayquerian”) of Urumaco (western Venezuela) is described as Hesperogavialis cruxenti n. gen., n. sp. It is the only known South American gavialid in which, as in the Gavialidae from the Indian region, the nasals do not come into contact with the premaxillae. This ressemblance with the gavials of India is interpreted as a result of convergent evolution.  相似文献
