Marasmius Rotula is a common species of Agaric fungus in the family Marasmiaceae. Widespread in the Northern Hemisphere, it is commonly known variously as the Pinwheel Mushroom, the Pinwheel Marasmius, the Little Wheel, the Collared Parachute, or the Horse Hair Fungus. The type species of the genus Marasmius, M. rotula was first described scientifically in 1772 by mycologist Giovanni Antonio Scopoli and assigned its current name in 1838 by Elias Fries.
Caudipteryx (which means "tail feather") is a genus of peacock-sized theropoddinosaurs that lived in the Aptian age of the early Cretaceous Period (about 124.6 million years ago). They were feathered and remarkably birdlike in their overall appearance. Two species have been described; C. zoui (the type species), in 1998, and C. dongi, in 2000
