AI analysisThis discovery challenges the previously held belief that certain South American predators had gone extinct earlier than thought. It suggests that these animals may have survived longer, potentially interacting with new species arriving from North America.
Where this goesUncertain45%weeks
Further discoveries of ancient South American predators could challenge existing theories about the timing of their extinction.
What would confirm it
- Further excavations in the area might uncover more evidence of Pampaluctor or similar species.
- Additional studies on other fossil sites in South America could reveal more about the timeline and interactions between native and immigrant predators.
