德克萨斯州拥有世界上最大的翼龙记录之一，在数量上超过了美国所有其他州和大多数国家。独特的是，这一记录涵盖了翼龙类的整个1.5亿+历史。对这一翼龙记录的回顾证实了至少有30种翼龙在13次出现中被发现，其中包括5个有效物种。其中两个种的全模已被描述过，并在此鉴定和建立为新种Radiodactylus langstoni，gen. et sp. nov.，以德克萨斯翼龙学之父小旺兰斯顿博士和拜地阿拉莫翼龙属新种命名。所有德克萨斯翼龙的系统发育分析，可以编码为一个以上的字符证实，这些物种是不同于其他物种，并占据系统发育位置接近其原始分类。Radiodactylus langstoni被确认为非无齿翼龙类的无齿翼龙，Quetzalcoatlus northropi被确认为无齿翼龙类，Alamodactylus byrdi被确认为非无齿翼龙类的无齿翼龙，Aetodactylus被确认为无齿翼龙类，Coloborhynchus wadleighi被确认为鸟手类。在德克萨斯州还发现了真双形翼龙、准噶尔翼龙以及其他无齿翼龙和翼龙。
The state of Texas has one of the greatest records of pterosaurs in the world, surpassing all other US states and most countries in the number of occurrences. Uniquely, this record extends over the entire 150+ million history of the Pterosauria. A review of this pterosaur record confirms at least 30 pterosaurs known from 13 occurrences, including five valid species. The holotypes of two of these species have been described before and are diagnosed and erected here as the new species Radiodactylus langstoni, gen. et sp. nov., named in honour of Dr. Wann Langston Jr, the father of Texas pterosaurology, and Alamodactylus byrdi, gen. et sp. nov.. Phylogenetic analysis of all Texas pterosaurs that can be coded for more than one character confirms that these species are distinct from others and occupy phylogenetic positions close to their original classifications. Radiodactylus langstoni is recovered as a non-azhdarchid azhdarchoid, Quetzalcoatlus northropi as an azhdarchid, Alamodactylus byrdi as a non-pteranodontoid pteranodontian, Aetodactylus as a pteranodontoid, and Coloborhynchus wadleighi as an ornithocheirid. The presence of eudimorphodontid, dsungaripterid, as well as other azhdarchid and pteranodontoid pterosaurs, is also confirmed in Texas.
