Spinosaurus: Shoreline Wader, Not Deep-Sea Diver?

Evidence from fossil distribution, anatomical features like the sail and tail, and calcium isotope analysis suggest that Spinosaurus was more likely a shoreline wader than a fully aquatic predator. Comparisons with modern waders and biomechanical models support this theory, while diving and pursuit predator ideas are questioned due to potential buoyancy and maneuverability limitations.

Possible Conflicts of Interest

None identified

Identified Weaknesses

Interpretative nature of evidence

The evidence for a wader lifestyle, while compelling, relies on interpretations of anatomical features and isotopes that could have other explanations, making it difficult to definitively conclude about the dinosaur's exact lifestyle.

Limited fossil evidence

The limited number of complete Spinosaurus skeletons hinders the study of its biomechanics and posture, leading to a reliance on models and comparisons with other animals that may not be entirely accurate.

Over-reliance on comparisons with extant species

While the comparison with modern organisms is helpful in understanding potential behaviors, it's crucial to remember that Spinosaurus was unique, and the behaviors of current species may not be fully applicable to this extinct animal.

Rating Explanation

This review presents a comprehensive overview of the current knowledge and debates surrounding Spinosaurus' lifestyle, combining various lines of evidence like fossil analysis, isotope studies, and biomechanical modeling. While some uncertainties remain, the study provides a strong case for the shoreline wader hypothesis. The authors also acknowledge alternative interpretations and limitations of the current data, enhancing the credibility of the analysis.
