Flamingos appear especially awkward when they are hard at work feeding because their filtering bristles are in the upper jaw and their head must be upside down to perform its function in the water. (realistic dinosaur)Bristle-toothed pterodactyls didn’t have to perform head-stands, because their filtering apparatus was located in the lower jaw, so the head could be lowered right side up into the water. (realistic dinosaur costume)Curiously enough, flamingos and bristle-toothed pterodactyls aren’t the only examples of algae-straining aerialists to evolve in the history of life. Forty-five million years ago a long-legged duck with flamingolike bristles in its lower jaw waded through the salty lakes of Wyoming, Colorado, and Utah. Fossil beds laid down in these briny lakes preserve the skulls, skeletons, footprints, and even some mound-type nests and the eggshells of the bristle-beaked duck. These three filter feeders are an extraordinary example of how evolutionary processes can shape unrelated clans into one and the same specialized ecological mode.
While on the subject of color, Dimorphodons snout deserves comment. (dinosaur factory)Seeley reconstructed this animal with a dark snout. But more likely Dimorphodon’s face was positively gaudy. Its high-snouted profile was more like a puffin’s than that of any other bird, and puffins employ their tall beaks to advertise their social status. Juvenile puffins start out quite drab in the snout, but adults are marked by faces run riot with white, red, and orange stripes and splotches. (big size dinosaur for sale)Dimorphodon deep snout cannot be explained by any hypothesis involving its jaw muscles or teeth. It’s quite likely that Dimorphodon snout evolved its unique high contours to advertise its owner’s rank in pterodactyl society. Since pterodactyls were highly visual creatures, with large eyes and bulbous optic hemi-spheres in their brain, it’s very probable in fact that colorful devices evolved many times among the various branches of the family tree. (life like dinosaur)Of course there is no direct evidence allowing reconstruction of the color pattern for any particular species of pterodactyl, but their color must have evolved to brighten Jurassic and Cretaceous skies in many ways.
