ArtistMasterpiece, highly detailed traditional ink and watercolor dinosaur illustration, expressive natural-history artwork, non-photorealistic. Subject: Dilophosaurus wetherilli, a slender, agile Early Jurassic theropod with two distinctive curved crests atop its skull, long narrow snout, sharp teeth, three-fingered hands, powerful hind legs, and a long balancing tail. Naturalistic muted olive-green and sandy-brown skin with subtle darker markings, alert predatory posture. Environment: ancient North American floodplain with ferns, cycads, conifers, damp ground, scattered stones, and distant mist beneath soft morning light. Dynamic three-quarter view, head raised slightly to display both crests clearly. Art style: intricate organic ink linework, delicate cross-hatching, fine anatomical contours, selective scale details, translucent watercolor washes, visible brushstrokes, natural pigment granulation, preserved white-paper highlights, earthy greens and ochres, handcrafted archival paper texture, museum-quality prehistoric natural-history illustration. Add a small, elegant, swooping cursive black signature “RY” in the bottom-right corner. Negative prompt: text, captions, labels, numbers, watermark, logo, border, frame, neck frill, venom-spitting effects, oversized crests, inaccurate anatomy, extra limbs, duplicated body parts, blurry details, photorealism, CGI, 3D render, cartoon style.
📚 Dinosaur Information — #07
🦖 Dilophosaurus (Dilophosaurus wetherilli)
"Two-Crested Lizard"
📌 Quick Facts
* 🔬 Scientific Name: Dilophosaurus wetherilli
* 🏷️ Group: Theropoda — Dilophosauridae
* 💡 Name Meaning: Two-Crested Lizard
* ⏳ Geological Period: Early Jurassic (approximately 186–183 million years ago)
* 📍 Discovery Location: Arizona, Southwestern United States (Kayenta Formation)
📏 Size & Characteristics
* 📏 Length: Approximately 6–7 metres
* 📐 Height: Roughly 1.5–2 metres at the hips
* ⚖️ Weight: Around 300–500 kg (commonly cited range)
* 🥩 Diet: Carnivore (likely preyed on smaller animals and fish)
📖 Overview
Dilophosaurus was one of the earliest large predatory dinosaurs, dominating the landscapes of Early Jurassic North America long before famous theropods like Allosaurus or T. rex evolved.
* 👑 Bony Crests:
Its most recognizable feature was a pair of thin, parallel, bony crests running along the top of its skull. These crests were likely used for species identification or visual display.
* 💀 Unique Skull Shape:
It possessed a lightweight skull with a narrow snout and a distinct notch located just behind the first row of teeth in its upper jaw.
* 🏃 Agile Anatomy:
Built with a slender body, long hind legs, and long forelimbs with four clawed fingers, Dilophosaurus was an agile hunter.
💡 Interesting Fact
🎬 Movie Myths vs. Reality:
Unlike its famous portrayal in Jurassic Park, there is no scientific evidence that Dilophosaurus spat venom or had a expandable neck frill! Furthermore, the real dinosaur was much larger—measuring around 6 to 7 metres long—than the small frilled creature seen in the film.
🔬 Scientific Note
While fossilized bones confirm the presence of its double crest, the exact soft-tissue covering, skin texture, and color patterns of the crests in life remain open to scientific interpretation.
