The fossil was identified as belonging to a fish-eating marine crocodile, measuring about 3 meters in length. This was a juvenile individual, not yet reaching its maximum size when it died.
The fossil was discovered in late 2023 in near-perfect condition in the Ocucaje Desert, about 350 kilometers south of Peru's capital Lima.
According to paleontologist Mario Gamarra, who led the research team, this is the first time scientists have found a fossil of a young individual of this species. What is special is that the skull and jaw of this marine crocodile have a different structure compared to today's crocodiles and alligators.
This ancient marine crocodile is believed to have had a longer snout and a diet entirely of fish. Gamarra also said that it is most closely related to the modern Indian gharial, a species known for its distinctive long snout.
This important fossil discovery is the result of a collaboration between the Institute of Geology, Mining and Metallurgy of Peru and the University of La Union. The study and reconstruction of the fossil has provided valuable information about the marine ecosystem during the Miocene period, about 5-23 million years ago.
The Ocucaje Desert, where the fossil was found, is known for its rich paleontological heritage. In the past, the area has yielded fossils of quadrupedal dwarf whales, dolphins, sharks and other Miocene creatures.
The discovery not only sheds light on the evolution of marine crocodiles, but also cements Ocucaje's place as an important site for global paleontological research.
