Fossils found 1,000 km inland show Spinosaurus mirabilis waded in freshwater rivers, challenging prior aquatic swimmer theories, researchers say.
- Fossils of a new Spinosaurus species, named Spinosaurus mirabilis, were discovered in Niger in 2022, dating back about 95 million years.
- Spinosaurus mirabilis was about 40 feet long, weighed 5-7 tonnes, and had a large, distinctive scimitar-shaped crest likely used for display.
- The species was adapted to stalking and catching large fish in shallow inland waterways and was not fully aquatic.
- The discovery provides new insights into Spinosaurus distribution and behavior, indicating a presence across North Africa, and was published by a team including University of Chicago paleontologist Paul Sereno.
