Ruixinia

Naam beteken: “Ruixin's, after Ruixin Zhang who helped the museum”1

Ruixinia was a long-necked, plant-eating dinosaur that lived in what is now China. It had a very long tail with at least 52 bones, and the last few tail bones were fused together into a rod-like tip.1

Prettige feite

Ruixinia's neck was over 4 meters long and had at least 15 neck bones, similar to other long-necked dinosaurs like Euhelopus and Mamenchisaurus.1

Its tail contained at least 52 vertebrae, and the last few were fused into a rod-like structure, a rare feature only seen in some Jurassic Asian sauropods.1

The chevron bone of the 20th tail vertebra had a pentagonal (five-sided) shape, which is unusual.1

Ruixinia lived alongside two other sauropods, Dongbeititan and Liaoningotitan, in the Jehol Biota ecosystem.1

Scientists disagree about whether Ruixinia was a titanosaur or a euhelopodid, because different studies place it in different groups.1

Vir dino-kenners

Wetenskaplike naam: Ruixinia
Benoem deur: Mo et al. 20234
Groep: Langnekke
Familie / klade: Euhelopodidae4
Klassifikasie: Sauropodomorpha > Sauropoda > Macronaria4
Ouderdom van die rotse: 126 tot 120 miljoen jaar (Barremian / Aptian)4
Rotsformasies: Yixian4
Lande: China4
Fossielrekords: 1 in The Paleobiology Database4
Ontdekking: Ruixinia was named in 2022 by Jinyou Mo and colleagues, based on a partial skeleton found in the Yixian Formation of Liaoning, China. The species name honors Ruixin Zhang, who helped the Erlianhaote Dinosaur Museum.1
Steeds omstrede: Scientists are still debating whether Ruixinia was a titanosaur or a euhelopodid, because different studies place it in different dinosaur family trees.1
