As penas são crescimentos epidérmicos que formam uma cobertura externa distinta, ou plumagem, em dinossauros, tanto avianos (Aves) quanto alguns não-avianos (que não são aves) e possivelmente outros Archosauromorpha. Elas são consideradas as mais complexas estruturas tegumentárias encontradas nos vertebrados e um exemplo importante de uma novidade evolucionária complexa. Elas estão entre as características que distinguem as aves vivas de outros grupos vivos. Embora as penas cubram a maior parte do corpo das aves, elas surgem apenas de certos tratos bem definidos na pele. Eles auxiliam no vôo, no isolamento térmico e na impermeabilização. Além disso, a coloração ajuda na comunicação e proteção.
