The recent discovery of two 210-million-year-old crocodile cousins offers an intriguing glimpse into the early diversification of these reptiles before the age of dinosaurs. Found in New Mexico, these fossils are part of a lineage that would eventually lead to modern crocodiles.
Researchers identified the two new species as Hesperosuchus agilis and Eosphorosuchus lacrimosa. Both creatures likely fell victim to a flash flood, preserving their remains in remarkable detail. This fossil discovery is particularly significant as it represents one of the few well-preserved early relatives of crocodiles.
Key insights from the discovery:
- The fossils date back to approximately 210 million years ago.
- They provide valuable information about the functional diversification in the lineage leading to modern crocodiles.
- This period marks a crucial point in the evolutionary history of reptiles.
Margulis-Ohnuma, a key researcher on this project, stated, “Eosphorosuchus is one of only a handful of well-preserved early crocodile relatives, and its coexistence with Hesperosuchus represents the ‘dawn’ of functional diversification in the lineage that would give rise to modern crocodiles.” This insight connects paleontology with broader themes in evolutionary biology.
