Supernova nucleosynthesis. Supernova nucleosynthesis is a theory of the production of many different chemical elements in supernova explosions, first advanced by Fred Hoyle in 1954. The nucleosynthesis, or fusion of lighter elements into heavier ones, occurs during explosive oxygen burning and silicon burning processes. Those fusion reactions create the elements silicon, sulfur, chlorine, argon, sodium, potassium, calcium, scandium, titanium and iron peak elements: vanadium, chromium, manganese, iron, cobalt, and nickel.
While the AKC requires poodles competing in the standard class to be over 15 inches at the shoulder, most average around 22 to 26 inches. Dogs marketed as royal or giant run from 25 to 31 inches tall at the shoulder. While some breeders charge a premium for larger dogs, they are registered with the AKC as a standard poodle. There is no advantage to their size in the show ring.
There is no royal or giant poodle. Anyone who refers to a poodle as royal or giant does not know what they are talking about. If it is a breeder, run far, far away! You are correct. The only AKC recognized sizes are Standard, Miniature and Toy.
