Exempel på hur man kan använda SAUROPODOMORPHS i en mening

• The early sauropodomorphs were most likely omnivores as their shared common ancestor with the other saurischian lineage (the theropods) was a carnivore.
• However, these definitions also take in many other former "prosauropods", and Adam Yates has proposed a definition of Sauropoda that will specifically exclude Melanorosaurus (Sauropoda as all sauropodomorphs closer to Saltasaurus than Melanorosaurus).
• Sauropods descend from basal sauropodomorphs (informally called "prosauropods"), which were primitively bipedal (two-legged).
• Yunnanosaurus huangi and Yunnanosaurus robustus shared their paleoenvironment with the ornithischians Bienosaurus, and Tatisaurus, the sauropodomorphs Gyposaurus, Lufengosaurus, and Jingshanosaurus, and the theropods Sinosaurus triassicus and Eshanosaurus.
• Despite being a true sauropod, the long bone development of Antetonitrus was more characteristic of basal sauropodomorphs, with subadults possessing, as derived sauropods do, highly vascularised fibrolamellar bone throughout their cortices, but with intermittent growth lines as seen in more basal sauropodomorphs instead of the absence of growth lines or presence of growth lines exclusively in the outer circumferential layer.
• The beginning of the Toarcian was a time of significant faunal turnover for sauropodomorphs, as all sauropodomorph lineages except for sauropods died out and eusauropods, which became the dominant sauropod group in the Middle Jurassic, began to diversify.
• Lydekker (1888) synonymized Gresslyosaurus with Zanclodon, but von Huene (1908) removed sauropodomorph material assigned to Zanclodon (which he assigned to Theropoda) and Gresslyosaurus along with Plateosaurus as sauropodomorphs.
• Its fossils were originally believed to belong to "prosauropods" (basal sauropodomorphs), but its original description and numerous subsequent papers argued that it was a herrerasaurid or herrerasaurian.
• Bonaparte and colleagues (2007) found that guaibasaurids have more characteristics in common with theropods than they do with early sauropodomorphs (or "prosauropods").
• Massospondylids have been recovered as the sister group (most closely related group) to more derived sauropodomorphs, including Sauropoda itself, and are more derived than groups like Plateosauridae.
• However, Quebrada del Barro is more abundant in sphenodontians (Sphenotitan), tritheledontid cynodonts, and coelophysoid dinosaurs (Lucianovenator), while sauropodomorphs are somewhat less common and aetosaurs are completely absent, in contrast to the Los Colorados Formation.
• A lamina connecting the diapophysis to the prezygapophysis on all dorsals, but not in no-sauropod sauropodomorphs, is present in the posterior dorsals.
• The size of the posterodorsal process is more in line with Herrerasaurus and ornithischians than with traditional theropods or sauropodomorphs.
• In 2022, Aureliano and colleagues performed a mirco-computed tomography scan on the postcranial skeletons of some of the earliest saurischian dinosaurs that lived during the late Carnian including Gnathovorax with sauropodomorphs Pampadromaeus and Buriolestes, which showed that the invasive air sac system was absent and that their bones were not pneumatised.
• A facultively quadrupedal prosauropod which displays transitional characters connecting more primitive obligate bipedal forms with the more derived obligative quadrupedal sauropodomorphs.
• However, by the middle Norian faunal assemblages were becoming disparate, particularly evident between high-latitude locations in Europe (including sauropodomorphs, phytosaurs, aetosaurs and turtles) and the lower-latitude southern United States (including dinosauromorphs, metoposaurs, phytosaurs, aetosaurs and non-archosaur archosauromorphs).
• In 2022, Aureliano and colleagues performed a mirco-computed tomography scan on the postcranial skeletons of some of the earliest saurischian dinosaurs that lived during the late Carnian including Gnathovorax with sauropodomorphs Pampadromaeus and Buriolestes, which showed that the invasive air sac system was absent and that their bones were not pneumatised.
• "Fendusaurus", according to Fedak, can be distinguished from all closely related sauropodomorphs by the extreme elongation of the cervical vertebrae; a four vertebrae sacrum that includes a dorsosacral and caudosacral; the elongate postacetabular process of the ilium; and an expanded anterior distal process of the tibia.
• Macrocollum itaquii differs from all other known sauropodomorphs based on a unique combination of characters such as those found on the skull, which include an antorbital fossa perforated by a promaxillary fenestra, and a medial margin of the supratemporal fossa with a simple smooth curve at the frontal/parietal suture.
• In 2022, Aureliano and colleagues performed a mirco-computed tomography scan on the postcranial skeletons of some of the earliest saurischian dinosaurs that lived during the late Carnian including Gnathovorax with sauropodomorphs Pampadromaeus and Buriolestes, which showed that the invasive air sac system was absent and that their bones were not pneumatised.
