摘要
Saratovia glickmani, gen. et sp. nov.基于俄罗斯萨拉托夫上白垩统(上Cenomanian) Melovatka组的一个齿状联合碎片进行了描述。该标本由L.S. Glickman于20世纪40年代末发现,以前被称为Ornithocheirus, anhananguera或Coloborhynchus。S. glickmani属于targaryendronia,因为其牙髓联合侧缘呈强烈扇贝状且近平行,横向狭窄,肺泡间隙宽度接近肺泡宽度。它与所有已知的坦格利安龙的不同之处在于它有一个齿状冠。该新分类群与所有有齿翼手类的不同之处在于在齿状联合上缺乏中间沟。相反,它有一个凸起的扁平平台,上面有许多相对较大的营养孔,这些孔由平台内的短管和中间管连接。S. glickmani是化石记录中已知的最新的有齿翼龙之一。
A new ornithocheiran pterosaur from the Upper Cretaceous (Cenomanian) of Saratov, Russia.
Saratovia glickmani, gen. et sp. nov., is described based on a dentary symphysis fragment from the Upper Cretaceous (upper Cenomanian) Melovatka Formation at Saratov, Russia. This specimen was found by L.S. Glickman in late 1940s and was referred previously to Ornithocheirus, Anhanguera, or Coloborhynchus. S. glickmani is attributed to Targaryendraconia because of strongly scalloped and subparallel lateral margins of dentary symphysis, which is transversely narrow, with the interalveolar width subequal to the alveolar width. It differs from all known targaryendraconians by having a dentary crest. The new taxon differs from all toothed pterodactyloids by lack of median groove on dentary symphysis. Instead, it has a raised flat platform pierced by numerous relatively large nutrient foramina, which are connected by short canals with a median canal within this platform. S. glickmani is one of the latest toothed pterosaurs known in the fossil record.
期刊介绍:
The Brazilian Academy of Sciences (BAS) publishes its journal, Annals of the Brazilian Academy of Sciences (AABC, in its Brazilianportuguese acronym ), every 3 months, being the oldest journal in Brazil with conkinuous distribukion, daking back to 1929. This scienkihic journal aims to publish the advances in scienkihic research from both Brazilian and foreigner scienkists, who work in the main research centers in the whole world, always looking for excellence.
Essenkially a mulkidisciplinary journal, the AABC cover, with both reviews and original researches, the diverse areas represented in the Academy, such as Biology, Physics, Biomedical Sciences, Chemistry, Agrarian Sciences, Engineering, Mathemakics, Social, Health and Earth Sciences.
