Why It Matters
🔬 Scientific Significance:
-
Demonstrates gigantism in tropical wetlands
-
Extreme bite force suggests bone-crushing capability
🌎 Modern Parallel: Climate change could favor new crocodylian giants
Visual Reconstruction Tips
-
Scales: Dorsal osteoderms like armored plates
-
Color: Dark with algae-green patches (swamp camouflage)
-
Scene: Ambushing a Stupendemys turtle herd
Rating: 9.5/10 (Would benefit from fossil site map)
