En los acantilados entre las playas de Munielles y Bahínas aflora la Formación Areniscas de Furada (Formación Furada), la cual marca el tránsito entre el Silúrico y el Devónico. Estos depósitos se acumularon en un ambiente marino somero afectado por sedimentación episódica, en parte como resultado de tempestades. Sobre la base del estudio de material en colecciones y nuevo trabajo de campo, se identifican, describen e ilustran 36 icnotaxones distintos: Arenicolites isp., Asterosoma ludwigae, Bergaueria hemispherica, Bifungites munizi, Chondrites isp., Cruziana acacencis, Cruziana quadrata, Curvolithus multiplex, Davichnia cantabrica, Dimorphichnus isp., Gordia marina, Halopoa imbricata, Heimdallia chatwini, Helicodromites mobilis, Helminthoidichnites tenuis, Helminthopsis abeli, Imponoglyphus isp., Lockeia siliquaria, Monomorphichnus isp. A, Monomorphichnus? isp., Nereites isp., Palaeophycus tubularis, Phycodes circinatum, Planolites montanus, Protovirgularia dichotoma, Psammichnites implexus, Psammichnites plummeri, Ptychoplasma excelsum, Rusophycus pudicus, Rusophycus isp. A e isp. B, Rosselia socialis, Skolithos isp., Teichichnus rectus, Trichophycus isp., y huellas indeterminadas. Las asociaciones documentan una amplia variedad de categorías etológicas correspondientes a diversos tipos tróficos, aunque con dominio de depositívoros y detritívoros. La asociación en su conjunto registra una diversa comunidad bentónica, si bien las suites muestran individualmente una icnodiversidad moderada a baja. La icnofauna estudiada ilustra un ejemplo silúrico-devónico de la Icnofacies de Cruziana.

: We report the first Upper Cretaceous marine reptile fossil in Ecuador, identified as an incomplete right maxilla from the Mosasauridae family. The remains were unearthed from marine marlstones and limestones within a karstic cave in the Tamia Yura indigenous community, situated northeast of Tena in the central Subandean Zone of the Ecuadorian Amazon. Morphological analysis reveals seven preserved teeth conical in shape. Stratigraphic analysis suggests the remains belong to the Middle Napo Fm., Oriente basin, indicating a presence from the Turonian to the end of the Coniacian. This discovery offers new insights into the study of Cretaceous marine reptiles in South America.
:我们报告了厄瓜多尔的第一具上白垩世海洋爬行动物化石，经鉴定为沧龙科（Mosasauridae）不完整的右上颌骨。这具化石是从位于厄瓜多尔亚马逊中部苏班德安地区特纳东北部的塔米亚尤拉土著社区一个喀斯特洞穴中的海洋泥灰岩和石灰岩中发掘出来的。形态分析显示，保存下来的七颗牙齿呈圆锥形。地层分析表明，这些遗骸属于 Oriente 盆地的纳波地层中段，表明从图伦纪到科尼亚纪末期一直存在。这一发现为研究南美洲白垩纪海洋爬行动物提供了新的视角。

The Chinese early Cretaceous Confuciusornis sanctus is the most abundant Mesozoic bird and a model species for studies of early avian evolution. 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.

El yacimiento paleontológico de Quibas es un afloramiento kárstico con una edad comprendida entre 1,1 y 0,9 Ma (Pleistoceno Inferior final). 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).
