Norellraptor is a microraptorian dinosaur known from a specimen with exceptionally well-preserved feathers. Its discovery supports evidence that gliding and flight-related traits evolved independently in multiple dinosaur groups. Norellraptor had long feathers on its arms and legs, typical of microraptorians, resulting in a four-winged body plan.

Various fossils pertaining to the holotype of the Triassic ichthyosaur Toretocnemus californicus. This image is derived from plate 24 in Merriam (1903), done by an uncredited artist. The arrangement of the individual figures has been modified from the original. Original description: Toretocnemus californicus n. gen. and sp. Figures reproduced natural size from the type specimen. Fig. 1. — Inferior side of right posterior limb. t, tibia. Fig. 2. — Right anterior limb. r, radius. Fig. 3.— Pelvic arch. Fig. 4. — Middle dorsal vertebrae and a rib from the same region.
