Gwyneddosaurus is a possibly invalid genus of extinct aquatic tanystropheid reptile. The type species, G. erici was described in 1945 by Wilhelm Bock, who identified it as a coelurosaurian dinosaur related to Podokesaurus (at the time, "podokesaurids" were thought to be coelurosaurians). Its remains were found in the Upper Triassic Lockatong Formation of Montgomery County, eastern Pennsylvania, and the holotype includes skull fragments, several vertebra, ribs, gastralia, partial shoulder and hip bones, and several forelimb and hindlimb elements found in soft shale, while the paratype includes a femur and a tibia. The type specimen is ANSP 15072 and it was discovered by Bock's four-year-old son while the paratype is only listed as ?(ASNP coll.). It was not a large animal; the type skeleton

- 格威內德龍（學名：Gwyneddosaurus）屬於原龍目長頸龍科，是種水生爬行動物。化石發現於美國賓州東部蒙哥馬利縣的一個頁岩層，屬於Lockatong組，年代為三疊紀晚期。 化石包含顱骨碎片、數節脊椎、肋骨、、部分肩帶與骨盆、以及數個四肢骨頭。正模標本（編號15072），是由Wilhelm Bock的四歲兒子所發現。股骨的長度只有2.3公分，Wilhelm Bock估計該標本的生前身長為23公分。 格威內德龍是在1945年由Wilhelm Bock命名，當時屬於虛骨龍類恐龍，是快足龍的近親。在1948年將牠們歸類到原龍類（Protorosauria），成為最小的原龍類，並是巨踝足龍的近親。在1970年，R. Steel將格威內德龍分類於獸腳亞目。在1986年，P.E. Olsen與D. Baird提出這些化石是個嵌合體，由腔棘魚類與的化石所構成。在1989年，P.E. Olsen與D. Baird修正原本的意見，大部分化石來自於塔尼龍，而其他化石可能屬於腔棘魚類。這將使得格威內德龍成為塔尼龍的次異名，雖然塔尼龍的命名年代較晚，但化石較為完整，所以成為保留名稱。 (zh)

No era un animal grande; Bock estimó que el esqueleto tipo era de 18 centímetros de largo, y su hueso del muslo tenía solo 23 milímetros de largo. Friedrich von Huene asignó el animal a Protorosauria en 1948 como el miembro más pequeño conocido del grupo, encontrándolo más parecido a Macrocnemus. Steel (1970) lo clasificó como un dinosaurio terópodo, mientras que Olsen y Baird (1986) lo identificaron como una quimera de restos mixtos de un celacanto y posiblemente del tanistroféido Tanytrachelos; Olsen y Flynn (1989) modificaron más tarde esta interpretación, describiendo el espécimen tipo de Gwyneddosaurus como una "eyección gástrica" (regurgitación) compuesta de huesos de Tanytrachelos y posiblemente restos de un celacanto. Señalaron que esto convertiría a Gwyneddosaurus en un sinónimo principal de Tanytrachelos y recomendaron conservar el género más joven pero mejor representado. (es)

It was not a large animal; the type skeleton was estimated by Bock as 18 centimetres (7.1 in) long, and its thigh bone was only 23 millimeters long (0.91 in). Friedrich von Huene assigned the animal to Protorosauria in 1948 as the smallest known member of the group, finding it to be most like Macrocnemus. Steel (1970) classified it as a theropod dinosaur, whereas Olsen and Baird (1986) identified it as a chimera of mixed remains from a coelacanth and possibly the tanystropheid Tanytrachelos; Olsen and Flynn (1989) later modified this interpretation, describing the type specimen of Gwyneddosaurus as a "gastric ejection" (regurgitation) composed of Tanytrachelos bones and possibly scraps of a coelacanth. They noted that this would make Gwyneddosaurus a senior synonym of Tanytrachelos, and recommended conserving the younger but better-represented genus. (en)
