{# ═══════════════════════════════════════════════════════════════════════════ Key differences (from DinoComparison model) ═══════════════════════════════════════════════════════════════════════════ #}

主要差异

Spinosaurus (15 m, ~7,400 kg) was larger than Carcharodontosaurus (12 m, ~6,200 kg).
Both lived in North Africa during the Cretaceous and may have coexisted in the same ecosystem.
Spinosaurus was semi-aquatic and primarily piscivorous; Carcharodontosaurus was a terrestrial apex predator hunting large dinosaurs.
Carcharodontosaurus had serrated, shark-like cutting teeth; Spinosaurus had conical, unserrated teeth adapted for gripping fish.
Their coexistence in the Kem Kem Beds suggests niche partitioning — one dominated water, the other land.
