While previous investigations were largely focused on aspects of the anatomy, taxonomy and systematics, and life history and ecology of this bird, there has been minimal research on its flight properties. Our study centers on a well-preserved specimen with exquisite details of its plumage. NHMW 1997z0112/0001 affords novel information on aspects of its skeletal morphology, particularly from the axial and appendicular skeletons, and its plumage provides the opportunity to quantify key flight-related variables including, wingtip, wing chord, body mass, wingspan, and wing area. We use these parameters to provide a quantitative assessment of the flight properties of C. sanctus . Most previous studies have suggested that this species was unable to achieve prolonged flights. However, our results indicate that the capacity for this bird to perform prolonged flights cannot be discarded, given that our data shows it might have been able to combine periods of flapping with periods of efficient low-speed gliding. Specifically, our results indicate that while having slightly less capacity than modern gliding birds, the gliding capacity of C. sanctus would have been significantly higher than that of modern short-term fliers such as land fowl. On the basis of these inferences, we conclude that C. sanctus could fly efficiently for prolonged periods of time when used a combination of flapping and gliding periods.","PeriodicalId":21954,"journal":{"name":"Spanish Journal of Palaeontology","volume":"16 9","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135934278","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Representa la única secuencia continua de vertebrados terrestres de edad pre-Jaramillo a Jaramillo de Europa. Está formado por dos estructuras principales: Quibas-Sima (dividida en las unidades QS-1 a QS-7) y Quibas-Cueva (QC-1–QC-6). En este trabajo se estudia la composición mineralógica de los sedimentos que conforman las unidades estratigráficas de Quibas-Sima, a través de análisis de difracción de rayos X, conductividad eléctrica, cromatografía iónica y espectrometría de emisión óptica por plasma de argón, con el objetivo de evaluar tendencias paleoclimáticas en la secuencia. Los resultados preliminares indican que hay un aumento en las proporciones de carbonatos, yesos y halita desde QS-2 hacia QS-4 y QS-5 (1,07–0,99 Ma), lo que sugiere una progresiva disminución de las precipitaciones en el sureste peninsular hace un millón de años. Los datos son consistentes con el inicio de una fase glaciar, lo cual viene apoyado por la desaparición progresiva en Quibas-Sima de taxones afines a bosques y cursos de agua estables como la ardilla voladora Hylopetes sp. y el musgaño Neomys sp., en favor de la aparición de taxones ligados a espacios abiertos como la culebra bastarda (Malpolon monspessulanus) y la víbora hocicuda (Vipera latastei).","PeriodicalId":21954,"journal":{"name":"Spanish Journal of Palaeontology","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136133211","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
