Cruralispennia is an extinct genus of enantiornithean bird. The only known specimen of Cruralispennia was discovered in the Early Cretaceous Huajiying Formation of China and formally described in 2017. The type species of Cruralispennia is Cruralispennia multidonta. The generic name is Latin for "shin feather", while the specific name means "many-toothed". The holotype of Cruralispennia is IVPP 21711, a semi-articulated partial skeleton surrounded by the remains of carbonized feathers.

| - Cruralispennia ist eine ausgestorbene Gattung der Enantiornithes. Der Gattungsname leitet sich vom lateinischen crus "Unterschenkel" und penna "Stiftfeder" ab. Die Artenbezeichnung bedeutet "mehrzahnig" und bezieht sich auf die hohe Anzahl von Zähnen im Vergleich zu anderen Enantiornithes. Die Benennung und Beschreibung erfolgte 2017 durch Min Wang, Jingmai K O’Connor, Pan Yanhong und Zhonghe Zhou. (de)

- Cruralispennia es un género extinto de ave enantiornite, que vivió durante el Cretácico Inferior en China. La especie tipo y única conocida es Cruralispennia multidonta, cuyos restos fósiles se encontraron la Formación Huanjiying en la cuenca de Sichakou, en la provincia de Hebei al noreste de China, la cual data de hace 130,7 millones de años, durante la época del Barremiense del Cretácico. Los restos fósiles fueron catalogados como IVPP 21711 y son alojados en el Instituto de Paleontología de Vertebrados y Paleoantropología, constando de un esqueleto parcial completamente articulado con varias plumas asociadas, preservados en una única losa. El nombre del género deriva de las palabras latinas cruralis y penna, en referencia a las plumas crurales del tibiotarso, mientras que el nombre de (es)

- Cruralispennia is an extinct genus of enantiornithean bird. The only known specimen of Cruralispennia was discovered in the Early Cretaceous Huajiying Formation of China and formally described in 2017. The type species of Cruralispennia is Cruralispennia multidonta. The generic name is Latin for "shin feather", while the specific name means "many-toothed". The holotype of Cruralispennia is IVPP 21711, a semi-articulated partial skeleton surrounded by the remains of carbonized feathers. Cruralispennia lived alongside several other species of enantiornitheans, such as Protopteryx, in the Sichakou Basin of the Huajiying Formation, approximately 130.7 million years ago. Despite being one of the earliest known ornithothoraces, this genus possessed several features of derived enantiornitheans as well as some unusual traits convergent with ornithuromorphs, a group containing modern birds. Cruralispennia is also notable for having crural feathers originally described as possessing a unique form unknown in any other feathered animal. However, it has also been hypothesized that the holotype specimen had recently molted, and that the unusual feathers were simply new feathers which had yet to lose the thick sheath around the rachis.
