Crocodile Fossils

Caption

Researchers uncovered fossils from seven different species of crocodiles that lived together about 13 million years ago in the Pebas Formation in what is now the Amazon Basin of northeastern Peru. Their skulls and jaws, shown here, are extremely diverse: (1) Gnatusuchus pebasensis, (2) Kuttanacaiman iquitosensis, (3) Caiman wannlangstoni, (4) Purussaurus neivensis, (5) Mourasuchus atopus, (6) Pebas Paleosuchus, and (7) Pebas gavialoid. The three new species (1-3) are shown in illustrations below the respective fossils. Reconstructions by Javier Herbozo.
