Brontosaurus Beside a Prehistoric Waterfall
The scene places the huge, long-necked dinosaur near falling water and rocky valley walls. Brontosaurus walked on four sturdy legs and carried a long tail behind its massive body. The waterfall and rugged surroundings create a broad prehistoric habitat without showing the modern world.
Water in a Dinosaur’s Environment
Large plant-eating dinosaurs needed access to vegetation and water in their habitats. Waterfalls form where flowing water passes over a steep drop in resistant rock, and erosion gradually changes the surrounding valley. Fossil evidence helps scientists study ancient landscapes as well as the animals that lived in them.
Evidence-Based Colors for Brontosaurus and the Valley
- Brontosaurus skin: its exact color is unknown; natural browns, greens, or grays are plausible choices
- Dinosaur underside: could be shown in a lighter shade than the back
- Rocks: commonly gray, brown, tan, rust red, or nearly black
- Waterfall: clear water often appears white where it foams and pale blue where it reflects the sky
- Valley ground: may be brown, tan, reddish, or gray depending on the rock and soil
