Originally named Stereocephalus before it was discovered that that genus was already occupied, has also been referred to the nomen dubium Paleoscincus as well as to Ankylosaurus [68] [69] Skull of the holotype with an accompanying diagram: Europelta carbonensis: AR-1/10 [70] Museo Aragonés de Paleontología [70] Mid-Albian [70] Escucha ...
English: Size comparison of the ankylosaurid dinosaur Ankylosaurus magniventrus.The silhouette is based on a skeletal by GetAwayTrike. [1] The bone measurements used to scale the specimens come from Carpenter (2004). [2]
As some analyses, like that of Carpenter from 2001 or David B. Norman in 2021 find Scelidosaurus and possibly other early forms like Emausaurus and Scutellosaurus to fall closer to Ankylosaurus than Stegosaurus, Carpenter and later Norman suggested redefining Ankylosauria to limit it to the two subclades Nodosauridae and Ankylosauridae ...
Tarchia was a medium-sized ankylosaur, measuring around 5.5–6 metres (18–20 ft) long and weighing up to 2.5–3 metric tons (2.8–3.3 short tons). [9] [10] If ZPAL MgD I/113 indeed belongs to the genus, it would have belonged to an individual measuring 5.8–6.7 metres (19–22 ft) long.
Skull diagram of Kunbarrasaurus. Parankylosaurs, compared to the more well studied euankylosaurs, retain more traits seen in more primitive thyreophorans and stegosaurs. This is most applicable in the body, most distinctively seen in the possession of rather long and slender limbs.
Skeletal diagram of MPC 700/17. Tsagantegia was a medium to large-sized ankyosaur, with an estimated length of 6 to 7 m (20 to 23 ft) [2] [3] and weighing about 1 to 4 t (2,200 to 8,800 lb).
