pterodactyly

a very rare, and very serious genetic condition involving the presence of webbed fingers, wing-like arms, an air-sac skeletal system for flight, an aerodynamic dorsal, colorful crest, and feathers. Although individuals develop the capacity for flight, they can be trained to forage on the ground if their symptoms are controlled. It may be necessary to refer for developmental consults, such as speech therapy to reduce the occurrence of persistent squawking noises, and occupational therapy since dinosaurs often suffer from discrimination in the workplace.
