Species
Monolophosaurus jiangi
Monolophosaurus jiangiMonolophosaurus was a bipedal carnivore distinguished by a prominent midline crest running from its snout to between its eyes, which likely functioned as a visual display structure for species recognition or courtship. Roaming lush floodplains and lake basins during the Middle Jurassic, it relied on serrated, blade-like teeth and grasping three-fingered forelimbs to secure prey. Preserved skeletal remains show a flexible neck and relatively lightweight frame, indicating an agile predator capable of navigating dense vegetation in pursuit of game.

- Why interaction risk is low
- Extinct species; known exclusively from fossilized skeletal remains.
Responsible observation
- Museum observation: Study mounted fossil casts to observe the delicate, hollow cranial crest structure.
- Fossil identification: Distinguish its skull by the single midline crest rather than paired ridges seen in other theropods.
