A new species of early-diverging Sauropodiformes from the Lower ...
2020年7月3日 · Sauropodomorpha were herbivorous saurischian dinosaurs that incorporate Sauropoda and early-diverging sauropodomorphs. The oldest sauropodomorph remains are known from Late Triassic deposits,...
A Spanish saltasauroid titanosaur reveals Europe as a melting pot …
2024年9月4日 · The discovery of a new sauropod dinosaur from the Upper Cretaceous of Spain sheds light on the phylogenetic relationships of European titanosaurs. It supports the existence of two separate Ibero...
A new Middle Jurassic diplodocoid suggests an earlier ... - Nature
2018年7月24日 · This ‘pushing back’ of the origination times of major sauropod clades reinforces recent suggestions that the Early Jurassic was a critical phase in dinosaur evolution, characterized by highly ...
Macronaria is a clade of gigantic body-sized sauropod dinosaurs widely distributed from the Late Jurassic to the Late Cretaceous globally. However, its origin, early diversification, and dispersal are still controversial. Here, we report a new macronarian Yuzhoulong qurenensis gen. et sp. nov. excavated from the Middle Jurassic (Bathonian) Lower
A new juvenile sauropod specimen from the Middle Jurassic
2022年9月16日 · The Tibetan sauropod bones reveal the presence of a short-necked early-diverging sauropod in the Middle Jurassic Dongdaqiao Formation of Chaya County, Qamdo District. Among previously described taxa, the specimen is most closely similar to early-diverging eusauropods from the Middle Jurassic, the resemblances including the shortness of the ...
A derived sauropodiform dinosaur and other ... - SpringerOpen
2020年7月1日 · The origin of sauropods from more basal sauropodomorphs—the group formerly known as “prosauropods”, which is now generally considered to be paraphyletic (see e.g. McPhee et al. 2015; Otero et al. 2015; Apaldetti et al. 2018)—has recently come into focus with the identification of several “prosauropod” taxa as close relatives of sauropods (e.g. Y...
New titanosauriform (Dinosauria: Sauropoda) specimens from the ... - PeerJ
2019年8月20日 · Here, we present the first detailed study of the anatomically informative sauropod bones from the Tianyuan site, and reconsider their probable affinities within Sauropoda. The bones in the sample are not all proportionate in size to one another (see Tables 1 – 3 ) and in any case came from multiple stratigraphic levels, so multiple ...
New macronarian from the Middle Jurassic of Chongqing, China ...
2022年11月2日 · Here we report a new sauropod specimen, Yuzhoulong qurenensis gen. et sp. nov., from this locality (figure 1). It presents a new early branching macronarian morphology and phylogeny. This discovery increases information for a better understanding of the origin, early evolution and paleogeographic distribution of neosauropods.
centroparapophyseal lamina; POCDF, postzygapophyseal centrodiapophyseal fossa; PODL, Table 1. Currently recognized sauropod genera and species in the Upper Jurassic Morrison Formation of North America. Dyslocosaurus polyonychius potentially represents an additional valid sauropod species from this formation, but its stratigraphic
