Castignovolucris
''Castignovolucris'' (meaning "Castigno valley bird") is an extinct genus of enantornithe bird from the Late Cretaceous "continental red clays" of the Argiles et Grès à Reptiles Formation of France. It contains a single species, ''C. sebei'', which was named and described in 2023. Discovery and naming The holotype, MC-VCZ2-6, a right coracoid, was discovered sometime around the 1990s near Villespassans by Stéphane Sèbe and was donated to the Musée de Cruzy. ''Castignovolucris sebei'' was named and described by Buffetaut ''et al.'' (2023). Description ''Castignovolucris'' was estimated to have a wingspan of around and may have been long when fully grown, making it one of the largest known enantiornitheans to date. Paleobiology ''Castignovolucris'' would have been found on the Ibero-Armorican island in what is today Occitania, France France, officially the French Republic, is a country located primarily in Western Europe.

Éric Buffetaut
Éric Buffetaut (born 19 November 1950) is a French paleontologist, author and researcher at the Centre national de la recherche scientifique since 1976 where he is a Doctor of Science and Director of Research. Buffetaut is a specialist of fossil archosaurs, mainly dinosaurs and pterosaurs, and has published many books on paleontology. He is one of the major paleontologists to support the thesis of the fall of a meteorite as the main cause of the Cretaceous–Paleogene extinction event The Cretaceous–Paleogene (K–Pg) extinction event, also known as the K–T extinction, was the extinction event, mass extinction of three-quarters of the plant and animal species on Earth approximately 66 million years ago. The event cau ....

Enantiornithes
The Enantiornithes, also known as enantiornithines or enantiornitheans in literature, are a group of extinct Avialae, avialans ("birds" in the broad sense), the most abundant and diverse group known from the Mesozoic era. Almost all retained teeth and clawed fingers on each wing, but otherwise looked much like modern birds externally. Over seventy species of Enantiornithes have been named, but some names represent only single bones, so it is likely that not all are valid. The Enantiornithes became extinct at the Cretaceous–Paleogene boundary, along with Hesperornithes and all other non-avian dinosaurs. Discovery and naming The first Enantiornithes to be discovered were incorrectly referred to modern bird groups. For example, the first known species of Enantiornithes, ''Gobipteryx minuta'', was originally considered a paleognath related to ostriches and tinamou. The Enantiornithes were first recognized as a distinct lineage, or "subclass" of birds, by Cyril A. Walker in 1981. W ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
