: Middle Ordovician trilobites found in 11 fossil localities from the areas of Alpartir, Aladrén, Luesma and Fombuena (Zaragoza province), and south of Calamocha (Teruel province) are studied. Most records come from the Alpartir Member of the Castillejo Formation, which is dated as Dobrotivian in age (late Darriwilian according to the global scale), with the only exception of two localities that are slightly older, from late Oretanian
对萨拉戈萨省Alpartir、aladr、Luesma和Fombuena地区以及特鲁埃尔省Calamocha南部11个化石点发现的中奥陶世三叶虫进行了研究。大多数记录来自Castillejo组的Alpartir成员,其年代为Dobrotivian(根据全球尺度,为Darriwilian晚期),只有两个地方例外,它们的年代稍早,来自Oretanian晚期

"Carbonífero de Puertollano" Natural Monument (Puertollano basin, Spain): a window for the knowledge of Early Vertebrates “Carbonífero de Puertollano”自然纪念碑(Puertollano盆地,西班牙):早期脊椎动物知识的窗口

Coal mining at the Puertollano Carboniferous basin has led to the discovery and study of numerous fossiliferous layers, rich in chondrichthyan, actinopterigyan and tetrapod remains. The end of the mining operations and closure of the mines could also represent complete cease of palaeontological prospections and field work at the Puertollano basin. Fortunately, three quarries, called María Isabel, La Extranjera and La Tejera, have been declared a Natural Monument. Consequently, they are protected by law and reserved for geological and palaeontological scientific research. In this paper, we describe the geology of the Natural Monument and its vertebrate fossil record. The outcrops of the three quarries show the most superficial part of the stratigraphic series so that they inform about the latest stages of the sedimentological and palaeogeographical evolution of the Puertollano basin. The actual coal basin appears to represent a remnant of a much larger basin which opened eastward to the Palaeo-Tethys. The diverse chondrichthyan assemblage (acanthodians, xenacanths and euselachians) and euryhaline actinopterygians, and the presence of tidal rhythmites, indicate an estuarine-deltaic environment. Future sedimentological and palaeontological studies at the Natural Monument will inform about the degree of marine influence in the basin and the changes of the vertebrate communities. Resumen: La minería del carbón en la cuenca carbonífera de Puertollano, ha permitido el descubrimiento y estudio de numerosos niveles fosilíferos ricos en restos de condrictios, actinopterigios y tetrápodos. El final de la explotación del carbón y el cierre o restauración de las minas, pudo suponer la eliminación de toda posibilidad de futuras prospecciones paleontológicas. Afortunadamente, tres minas a cielo abierto, María Isabel, La Extranjera y La Tejera, han sido declaradas Monumento Natural y, por lo tanto, son áreas protegidas, reservadas para la investigación geológica y paleontológica. En este trabajo describimos la geología de las tres localidades del Monumento y estudiamos el contenido en vertebrados. En las tres minas afloran los niveles más superficiales de la cuenca, dando información de los momentos finales de sedimentación y evolución paleogeográfica de la cuenca de Puertollano. La cuenca carbonífera actual sería un resto de una cuenca mucho mayor conectada hacia el este con el Paleo-Tetis. La abundancia de condrictios (acantódidos, xenacántidos y euseláceos) y actinopterigios eurihalinos, y la existencia de ritmitas mareales, indica un ambiente de tipo estuarino-deltaico. Futuros estudios sedimentológicos y paleontológicos en el Monumento Natural informarán sobre el grado de influencia marina en la cuenca y los cambios de las comunidades de vertebrados.

Puertollano石炭纪盆地的煤炭开采导致发现和研究了许多富含软骨藻、放线菌和四足动物遗骸的化石层。采矿作业的结束和矿山的关闭也可能代表普尔托拉诺盆地古生物学勘探和实地工作的完全停止。幸运的是,三个名为玛丽亚·伊莎贝尔、外国人和织布工的采石场已被宣布为自然纪念碑。因此,它们受到法律的保护,并保留用于地质和古生物学科学研究。在这篇文章中,我们描述了这座自然古迹的地质及其脊椎动物化石记录。这三个采石场的露头显示了地层系列中最浅的部分,因此它们报告了普尔托拉诺盆地沉积学和古地理演变的最新阶段。实际的煤炭盆地似乎代表了一个更大的盆地的遗迹,该盆地向东向古特提斯开放。多样的软骨动物群(棘皮动物、异种动物和Euselachians)和Euryhaline actinopterygians,以及潮汐节律的存在,表明了河口三角洲环境。未来对自然古迹的沉积学和古生物学研究将报告盆地海洋影响的程度和脊椎动物群落的变化。摘要:普尔托拉诺石炭纪盆地的煤炭开采使人们能够发现和研究许多富含软骨病、放线菌和四足动物遗骸的化石水平。煤炭开采的结束和矿山的关闭或恢复可能意味着未来古生物学勘探的任何可能性都将被消除。幸运的是,三个露天矿,玛丽亚·伊莎贝尔、外国人和织布工,已被宣布为自然纪念碑,因此是保护区,专门用于地质和古生物学研究。在这篇文章中,我们描述了纪念碑的三个地点的地质情况,并研究了脊椎动物的含量。在这三个矿山中,盆地的最浅层浮出水面,提供了普尔托拉诺盆地沉积和古地理演变的最后时刻的信息。目前的石炭纪盆地将是一个更大的盆地的其余部分,该盆地向东与古特提斯盆地相连。软骨病(棘足动物、异种动物和真丛林动物)和宽鳍放线鸟的丰度以及潮汐节律的存在表明了河口三角洲类型的环境。未来对自然纪念碑的沉积学和古生物学研究将报告海洋对盆地的影响程度以及脊椎动物群落的变化。收到:2023年4月23日接受:2023年6月6日发布:2023年6月13日对应作者:

A new enantiornithine specimen from the Lower Cretaceous of Las Hoyas: avifaunal diversity and life-history of a wetland Mesozoic bird 来自Las Hoyas下白垩纪的一个新的反鸟目标本:湿地中生代鸟类的鸟类多样性和生活史

: The Lower Cretaceous fossil site of Las Hoyas (Cuenca, Spain) has yielded the richest Cretaceous avifauna of the European continent. We describe a new fossil (MUPA-LH-33333) of an enantiornithine bird from this locality. This specimen consists of a partially articulated skeleton preserving portions of the vertebral column, both girdles and limbs, ribs and sternum; it also preserves patches of soft tissues including remigial feathers and integumentary structures belonging to the postpatagium. MUPA-LH-33333 shares dimensions and some anatomical features with the holotype of Concornis lacustris , a species previously described from Las Hoyas. However, the new specimen shows differences especially in the coracoid and the sternum, suggesting the presence of a different morpho-type closely related to C. lacustris . Nevertheless, the poor preservation prevents asserting that it represents a new species. Histological evidence from its long bones indicates that is subadult or adult and that early fast rates followed by slower and protracted cyclical phases took place during its growth, a previously unnoticed pattern in Lower Cretaceous enantiornithines. This new finding supports the hypothesis that enantiornithines regularly inhabited the Las Hoyas wetland, making this site a hotspot for enhancing our understanding of the evolution and life history of these Cretaceous birds.
:Las Hoyas(西班牙昆卡)的下白垩纪化石遗址产生了欧洲大陆最丰富的白垩纪鸟类。我们描述了一个来自该地区的对硝基鸟的新化石(MUPA-LH-33333)。该标本由一个部分铰接的骨骼组成,保留了脊椎的部分,包括腰带和四肢、肋骨和胸骨;它还保留了软组织的斑块,包括胎体前羽毛和属于后片的珠被结构。MUPA-LH-33333与之前在Las Hoyas描述的湖螺的正模标本具有相同的尺寸和一些解剖特征。然而,新标本显示出差异,尤其是在喙和胸骨上,这表明存在一种与湖螈密切相关的不同形态类型。然而,由于保存不善,无法断言它代表了一个新物种。从其长骨中获得的组织学证据表明,它是亚成年或成年的,在其生长过程中发生了早期的快速生长,随后是缓慢而持久的周期性阶段,这是下白垩纪对生岩中以前未被注意到的模式。这一新发现支持了对映鸟纲动物经常栖息在Las Hoyas湿地的假设,使该地点成为加强我们对这些白垩纪鸟类进化和生活史了解的热点。

The dentition of Omalodontiformes, the order of unusual Devonian stem-chondrichthyans 泥盆纪不同寻常的茎软骨鱼目Omalodontiformes的牙列
Q4 Earth and Planetary Sciences Pub Date : 2023-05-09 DOI: 10.7203/sjp.26564

: The early chondrichthyan order Omalodontiformes from the late Early Devonian through to the Late Devonian is characterised by specific teeth. Unlike in most Devonian sharks, their bases are directed labially or are reduced and devoid of labial or lingual extensions. In this paper the complex history of investigation on the dermal skeleton of omalo-dontiforms is presented and the validity of the established taxa is revised. The dentition of an Emsian representative of this group , known from a single articulated specimen (NMBG 10127) and several isolated fin spines from Canada and previously, probably incorrectly, attributed to Doliodus , is distinctly heterodont. The nature of this heterodonty suggests that the two omalodontiform tooth-based genera described originally from the Middle–Upper Devonian Aztec Siltstone (Antarctica), viz . Portalodus and Anareodus , are in fact conge-neric as their teeth represent different parts of the same jaw. Because the teeth of the Canadian specimen differ in important aspects from those of typical Doliodus and are generally similar to those of Portalodus , it probably should be placed in a new genus. Also, the validity of the distinction between Portalodus bradshawae and P. mannoliniae is considered questionable.
早泥盆世晚期至晚泥盆世的早期软骨鱼目Omalodontiformes以特定的牙齿为特征。与大多数泥盆纪鲨鱼不同的是,它们的基部是唇形的,或者是缩小的,没有唇或舌的延伸。本文介绍了对齿形兽真皮骨骼的复杂研究历史,并对已建立的分类群的有效性进行了修正。这个群体的一个代表的emian的牙齿,从一个单一的铰接标本(NMBG 10127)和几个来自加拿大的孤立的鳍刺中得知,以前可能错误地认为是Doliodus,明显是异齿动物。这种异齿的性质表明,最初描述的两个以牙齿为基础的齿状异齿属来自泥盆纪中上阿兹特克粉砂岩(南极洲),即。Portalodus和Anareodus实际上是同源的,因为它们的牙齿代表了同一个颌骨的不同部位。由于加拿大标本的牙齿在重要方面与典型的Doliodus的牙齿不同,并且与Portalodus的牙齿大致相似,因此它可能应该被放在一个新的属中。此外,门门藻和甘露糖叶的区分的有效性也被认为是有问题的。
